Creating a local LLM Cluster Server using Apple Silicon GPU

Today, we’re going to discuss creating a local LLM server and then utilizing it to execute various popular LLM models. We will club the local Apple GPUs together via a new framework that binds all the available Apple Silicon devices into one big LLM server. This enables people to run many large models, which was otherwise not possible due to the lack of GPUs.

This is certainly a new way; One can create virtual computation layers by adding nodes to the resource pool, increasing the computation capacity.

Why not witness a small demo to energize ourselves –

Let us understand the scenario. I’ve one Mac Book Pro M4 & 2 Mac Mini Pro M4 (Base models). So, I want to add them & expose them as a cluster as follows –

As you can see, I’ve connected my MacBook Pro with both the Mac Mini using high-speed thunderbolt cables for better data transmissions. And, I’ll be using an open-source framework called “Exo” to create it.

Also, you can see that my total computing capacity is 53.11 TFlops, which is slightly more than the last category.

“Exo” is an open-source framework that helps you merge all your available devices into a large cluster of available resources. This extracts all the computing juice needed to handle complex tasks, including the big LLMs, which require very expensive GPU-based servers.

For more information on “Exo”, please refer to the following link.

In our previous diagram, we can see that the framework also offers endpoints.

  • One option is a local ChatGPT interface, where any question you ask will receive a response from models by combining all available computing power.
  • The other endpoint offers users a choice of any standard LLM API endpoint, which helps them integrate it into their solutions.

Let us see, how the devices are connected together –


To proceed with this, you need to have at least Python 3.12, Anaconda or Miniconda & Xcode installed in all of your machines. Also, you need to install some Apple-specific MLX packages or libraries to get the best performance.

Depending on your choice, you need to use the following link to download Anaconda or Miniconda.

You can download the following link to download the Python 3.12. However, I’ve used Python 3.13 on some machines & some machines, I’ve used Python 3.12. And it worked without any problem.

Sometimes, after installing Anaconda or Miniconda, the environment may not implicitly be activated after successful installation. In that case, you may need to use the following commands in the terminal -> source ~/.bash_profile

To verify, whether the conda has been successfully installed & activated, you need to type the following command –

(base) satyaki_de@Satyakis-MacBook-Pro-Max Pandas % conda --version
conda 24.11.3
(base) satyaki_de@Satyakis-MacBook-Pro-Max Pandas % 
(base) satyaki_de@Satyakis-MacBook-Pro-Max Pandas % 

Once you verify it. Now, we need to install the following supplemental packages in all the machines as –

satyaki_de@Satyakis-MacBook-Pro-Max Pandas % 
satyaki_de@Satyakis-MacBook-Pro-Max Pandas % 
satyaki_de@Satyakis-MacBook-Pro-Max Pandas % conda install anaconda::m4

Till now, we’ve installed all the important packages. Now, we need to setup the final “eco” framework in all the machines like our previous steps.

Now, we’ll first clone the “eco” framework by the following commands –

At the beginning, if we trigger the main MacBook Pro Max, the “Exo” screen should looks like this –

And if you open the URL, you will see the following ChatGPT-like interface –

Connecting without the Thunderbolt bridge with the relevant port or a hub may cause performance degradation. Hence, how you connect will play a major role in the success of this intention. However, this is certainly a great idea to proceed with.


So, we’ve done it.

We’ll cover the detailed performance testing, Optimized configurations & many other useful details in our next post.

Till then, Happy Avenging! 🙂

Monitoring & evaluating the leading LLMs (both the established & new) by Python-based evaluator

As we’re leaping more & more into the field of Generative AI, one of the frequent questions or challenges people are getting more & more is the performance & other evaluation factors. These factors will eventually bring the fruit of this technology; otherwise, you will end up in technical debt.

This post will discuss the key snippets of the monitoring app based on the Python-based AI app. But before that, let us first view the demo.

Isn’t it exciting?


Let us deep dive into it. But, here is the flow this solution will follow.

So, the current application will invoke the industry bigshots and some relatively unknown or new LLMs.

In this case, we’ll evaluate Anthropic, Open AI, DeepSeek, and Bharat GPT’s various models. However, Bharat GPT is open source, so we’ll use the Huggingface library and execute it locally against my MacBook Pro M4 Max.

    @retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=4, max=10))
    def get_claude_response(self, prompt: str) -> str:
        response = self.anthropic_client.messages.create(
            model=anthropic_model,
            max_tokens=maxToken,
            messages=[{"role": "user", "content": prompt}]
        )
        return response.content[0].text
  1. The Retry Mechanism
    • The @retry line means this function will automatically try again if it fails.
    • It will stop retrying after 3 attempts (stop_after_attempt(3)).
    • It will wait longer between retries, starting at 4 seconds and increasing up to 10 seconds (wait_exponential(multiplier=1, min=4, max=10)).
  2. The Function Purpose
    • The function takes a message, called prompt, as input (a string of text).
    • It uses a service (likely an AI system like Claude) to generate a response to this prompt.
  3. Sending the Message
    • Inside the function, the code self.anthropic_client.messages.create is the part that actually sends the prompt to the AI.
    • It specifies:Which AI model to use (e.g., anthropic_model).
    • The maximum length of the response (controlled by maxToken).
    • The input message for the AI has a “role” (user), as well as the content of the prompt.
  4. Getting the Response
    • Once the AI generates a response, it’s saved as response.
    • The code retrieves the first part of the response (response.content[0].text) and sends it back to whoever called the function.

Similarly, it will work for Open AI as well.

    def get_deepseek_response(self, prompt: str) -> tuple:
        deepseek_api_key = self.deepseek_api_key

        headers = {
            "Authorization": f"Bearer {deepseek_api_key}",
            "Content-Type": "application/json"
            }
        
        payload = {
            "model": deepseek_model,  
            "messages": [{"role": "user", "content": prompt}],
            "max_tokens": maxToken
            }
        
        response = requests.post(DEEPSEEK_API_URL, headers=headers, json=payload)

        if response.status_code == 200:
            res = response.json()["choices"][0]["message"]["content"]
        else:
            res = "API request failed with status code " + str(response.status_code) + ":" + str(response.text)

        return res
  1. Retry Mechanism:
    • The @retry line ensures the function will try again if it fails.
    • It will stop retrying after 3 attempts (stop_after_attempt(3)).
    • It waits between retries, starting at 4 seconds and increasing up to 10 seconds (wait_exponential(multiplier=1, min=4, max=10)).

  1. What the Function Does:
    • The function takes one input, prompt, which is the message or question you want to send to the AI.
    • It returns the AI’s response or an error message.

  1. Preparing to Communicate with the API:
    • API Key: It gets the API key for the DeepSeek service from self.deepseek_api_key.
    • Headers: These tell the API that the request will use the API key (for security) and that the data format is JSON (structured text).
    • Payload: This is the information sent to the AI. It includes:
      • Model: Specifies which version of the AI to use (deepseek_model).
      • Messages: The input message with the role “user” and your prompt.
      • Max Tokens: Defines the maximum size of the AI’s response (maxToken).

  1. Sending the Request:
    • It uses the requests.post() method to send the payload and headers to the DeepSeek API using the URL DEEPSEEK_API_URL.

  1. Processing the Response:
    • If the API responds successfully (status_code == 200):
      • It extracts the AI’s reply from the response data.
      • Specifically, it gets the first choice’s message content: response.json()["choices"][0]["message"]["content"].
    • If there’s an error:
      • It constructs an error message with the status code and detailed error text from the API.

  1. Returning the Result:
    • The function outputs either the AI’s response or the error message.

            # Extract 'content' field safely
            res = next((entry.get("content", "")
                        for entry in response[0][0].get("generated_text", [])
                        if isinstance(entry, dict) and entry.get("role") == "assistant"
                        ),
                        None,
                        )
            
            return res
        except Exception as e:
            x = str(e)
            print('Error: ', x)

            return ""
  1. Retry Mechanism:The @retry ensures the function will try again if it fails.
    • It will stop retrying after 3 attempts (stop_after_attempt(3)).
    • The waiting time between retries starts at 4 seconds and increases exponentially up to 10 seconds (wait_exponential(multiplier=1, min=4, max=10)).
  2. What the Function Does:The function takes one input, prompt, which is the message or question you want to send to BharatGPT.
    • It returns the AI’s response or an empty string if something goes wrong.
  3. Sending the Prompt:Messages Structure: The function wraps the user’s prompt in a format that the BharatGPT AI understands:
    • messages = [[{"role": "user", "content": prompt}]]
    • This tells the AI that the prompt is coming from the “user.”
  4. Pipe Function: It uses a pipe() method to send the messages to the AI system.
    • max_new_tokens=maxToken: Limits how long the AI’s response can be.
  5. Extracting the Response:The response from the AI is in a structured format. The code looks for the first piece of text where:
    • The role is “assistant” (meaning it’s the AI’s reply).
    • The text is in the “content” field.
    • The next() function safely extracts this “content” field or returns None if it can’t find it.
  6. Error Handling:If something goes wrong (e.g., the AI doesn’t respond or there’s a technical issue), the code:
    • Captures the error message in e.
    • Prints the error message: print('Error: ', x).
    • Returns an empty string ("") instead of crashing.
  7. Returning the Result:If everything works, the function gives you the AI’s response as plain text.
    • If there’s an error, it gives you an empty string, indicating no response was received.

                memory_usage=0,
                error=str(e)
            )

Start Tracking Time and Memory:

    • The function starts a timer (start_time) to measure how long it takes to get a response.
    • It also checks how much memory is being used at the beginning (start_memory).

    Choose the AI Model:

    • Based on the model_name provided, the function selects the appropriate method to get a response:
      • "claude-3" → Calls get_claude_response(prompt).
      • "gpt4" → Calls get_gpt4_response(prompt).
      • "deepseek-chat" → Calls get_deepseek_response(prompt).
      • "bharat-gpt" → Calls get_bharatgpt_response(prompt).

    Process the Response:

    • Once the response is received, the function calculates:
      • Token Count: The number of tokens (small chunks of text) in the response using a tokenizer.
      • Memory Usage: The difference between memory usage after the response (end_memory) and before it (start_memory).

    Return the Results:

    • The function bundles all the information into a ModelResponse object:
      • The AI’s reply (content).
      • How long the response took (response_time).
      • The number of tokens in the reply (token_count).
      • How much memory was used (memory_usage).

    Handle Errors:

    • If something goes wrong (e.g., the AI doesn’t respond), the function:
      • Logs the error message.
      • Returns an empty response with default values and the error message.

                'meteor_score': meteor
            }

    Inputs:

    • generated: The text produced by the AI.
    • reference: The correct or expected version of the text.

    Calculating BERTScore:

    • Converts the generated and reference texts into numerical embeddings (mathematical representations) using a pre-trained model (self.sentence_model.encode).
    • Measures the similarity between the two embeddings using cosine similarity. This gives the bert_score, which ranges from -1 (completely different) to 1 (very similar).

    Calculating BLEU Score:

    • Breaks the generated and reference texts into individual words (tokens) using word_tokenize.
    • Converts both texts to lowercase for consistent comparison.
    • Calculates the BLEU Score (sentence_bleu), which checks how many words or phrases in the generated text overlap with the reference. BLEU values range from 0 (no match) to 1 (perfect match).

    Calculating METEOR Score:

    • Also uses the tokenized versions of generated and reference texts.
    • Calculates the METEOR Score (meteor_score), which considers exact matches, synonyms, and word order. Scores range from 0 (no match) to 1 (perfect match).

    Returning the Results:

    • Combines the three scores into a dictionary with the keys 'bert_score''bleu_score', and 'meteor_score'.

    Similarly, other functions are developed.

    • Handle Errors:
      • If a response has an error, log the issue and skip further evaluation for that model.

      • Using the best_response, calculate a variety of metrics, including:
        • Text Quality: How similar the response is to the reference.
        • Factual Accuracy: Whether the response is factually correct.
        • Task Performance: How well it meets task-specific criteria.
        • Technical Performance: Evaluate time, memory, or other system-related metrics.
        • Reliability: Check consistency across multiple responses.
        • Safety: Ensure the response is safe and appropriate.
    • Evaluate Business Impact:
      • Add metrics for business impact (e.g., how well the task was completed, using task_completion as a key factor).
    • Store Results:
      • Add the calculated metrics for this model and prompt to the results list.
    • Return Results as a DataFrame:
      • Convert the results list into a structured table (a pandas DataFrame) for easy analysis and visualization.

    Great! So, now, we’ve explained the code.

    Let us understand the final outcome of this run & what we can conclude from that.

    1. BERT Score (Semantic Understanding):
      • GPT4 leads slightly at 0.8322 (83.22%)
      • Bharat-GPT close second at 0.8118 (81.18%)
      • Claude-3 at 0.8019 (80.19%)
      • DeepSeek-Chat at 0.7819 (78.19%) Think of this like a “comprehension score” – how well the models understand the context. All models show strong understanding, with only a 5% difference between best and worst.
    2. BLEU Score (Word-for-Word Accuracy):
      • Bharat-GPT leads at 0.0567 (5.67%)
      • Claude-3 at 0.0344 (3.44%)
      • GPT4 at 0.0306 (3.06%)
      • DeepSeek-Chat lowest at 0.0189 (1.89%) These low scores suggest models use different wording than references, which isn’t necessarily bad.
    3. METEOR Score (Meaning Preservation):
      • Bharat-GPT leads at 0.4684 (46.84%)
      • Claude-3 close second at 0.4507 (45.07%)
      • GPT4 at 0.2960 (29.60%)
      • DeepSeek-Chat at 0.2652 (26.52%) This shows how well models maintain meaning while using different words.
    4. Response Time (Speed):
      • Claude-3 fastest: 4.40 seconds
      • Bharat-GPT: 6.35 seconds
      • GPT4: 6.43 seconds
      • DeepSeek-Chat slowest: 8.52 seconds
    5. Safety and Reliability:
      • Error Rate: Perfect 0.0 for all models
      • Toxicity: All very safe (below 0.15%) 
        • Claude-3 safest at 0.0007GPT4 at 0.0008Bharat-GPT at 0.0012
        • DeepSeek-Chat at 0.0014
    6. Cost Efficiency:
      • Claude-3 most economical: $0.0019 per response
      • Bharat-GPT close: $0.0021
      • GPT4: $0.0038
      • DeepSeek-Chat highest: $0.0050

    Key Takeaways by Model:

    1. Claude-3: ✓ Fastest responses ✓ Most cost-effective ✓ Excellent meaning preservation ✓ Lowest toxicity
    2. Bharat-GPT: ✓ Best BLEU and METEOR scores ✓ Strong semantic understanding ✓ Cost-effective ✗ Moderate response time
    3. GPT4: ✓ Best semantic understanding ✓ Good safety metrics ✗ Higher cost ✗ Moderate response time
    4. DeepSeek-Chat: ✗ Generally lower performance ✗ Slowest responses ✗ Highest cost ✗ Slightly higher toxicity

    Reliability of These Statistics:

    Strong Points:

    • Comprehensive metric coverage
    • Consistent patterns across evaluations
    • Zero error rates show reliability
    • Clear differentiation between models

    Limitations:

    • BLEU scores are quite low across all models
    • Doesn’t measure creative or innovative responses
    • May not reflect specific use case performance
    • Single snapshot rather than long-term performance

    Final Observation:

    1. Best Overall Value: Claude-3
      • Fast, cost-effective, safe, good performance
    2. Best for Accuracy: Bharat-GPT
      • Highest meaning preservation and precision
    3. Best for Understanding: GPT4
      • Strongest semantic comprehension
    4. Consider Your Priorities: 
      • Speed → Choose Claude-3
      • Cost → Choose Claude-3 or Bharat-GPT
      • Accuracy → Choose Bharat-GPT
      • Understanding → Choose GPT4

    These statistics provide reliable comparative data but should be part of a broader decision-making process that includes your specific needs, budget, and use cases.


    For the Bharat GPT model, we’ve tested this locally on my MacBook Pro 4 Max. And, the configuration is as follows –

    I’ve tried the API version locally, & it provided a similar performance against the stats that we received by running locally. Unfortunately, they haven’t made the API version public yet.

    So, apart from the Anthropic & Open AI, I’ll watch this new LLM (Bharat GPT) for overall stats in the coming days.


    So, we’ve done it.

    You can find the detailed code at the GitHub link.

    I’ll bring some more exciting topics in the coming days from the Python verse.

    Till then, Happy Avenging! 🙂

    For, reference, we’ll share the demo before deep dive into the actual follow-up analysis in the below section –


    Now, let us continue our discussions from where we left.

    This is the initialization method for the clsText2Image class:

    • Takes a pre-configured pipe (text-to-image pipeline), an output_path, and a filename.
    • Enables more aggressive memory optimization by setting “attention slicing.”
    • Prepares the full file path for saving generated images.
    • Calls a _warmup method to pre-load the pipeline and optimize memory allocation.

    This private method warms up the pipeline:

    • Sends a dummy “warmup” request with basic parameters to allocate memory efficiently.
    • Clears any cached memory (torch.mps.empty_cache()) and performs garbage collection (gc.collect()).
    • Ensures smoother operation for future image generation tasks.

    This method generates an image from a text prompt:

    • Clears memory cache and performs garbage collection before starting.
    • Uses the text-to-image pipeline (pipe) to generate an image:
      • Takes the prompt, number of inference steps, and guidance scale as input.
      • Outputs an image at 1024×1024 resolution.
    • Saves the generated image to the specified output path.
    • Returns 0 on success or 1 on failure.
    • Ensures cleanup by clearing memory and collecting garbage, even in case of errors.

    This method simplifies image generation:

    • Calls the generate method with the given prompt.
    • Prints a success message if the image is generated (0 return value).
    • On failure, logs the error and raises an exception.
    • Returns 0 on success or 1 on failure.
    class clsImage2Video:
        def __init__(self, pipeline):

            try:
                print("Starting animation generation...")
                
                init_image_path = inputImage
                output_path = targetVideo
                fps = fps
                
                frames = self.generate_frames(
                    pipeline=self.pipeline,
                    init_image=init_image_path,
                    prompt=prompt,
                    duration_seconds=20
                )
                
                imageio.mimsave(output_path, frames, fps=30)
    
                print("Animation completed successfully!")
    
                return 0
            except Exception as e:
                x = str(e)
                print('Error: ', x)
    
                return 1

    This initializes the clsImage2Video class:

    • Clears the GPU cache to optimize memory before loading.
    • Sets up the pipeline for generating frames, which uses an image-to-video transformation model.

    This function generates frames for a video:

    • Starts by clearing GPU memory and running garbage collection.
    • Loads the init_image, resizes it to 1024×1024 pixels, and converts it to RGB format.
    • Iteratively applies the pipeline to transform the image:
      • Uses the prompt and specified parameters like strengthguidance_scale, and num_inference_steps.
      • Stores the resulting frames in a list.
    • Interpolates between consecutive frames to create smooth transitions:
      • Uses linear blending for smooth animation across a specified duration and frame rate (24 fps for 10 segments).
    • Returns the final list of generated frames or an empty list if an error occurs.
    • Always clears memory after execution.

    This is the main function for creating a video from an image and text prompt:

    • Logs the start of the animation generation process.
    • Calls generate_frames() with the given pipelineinputImage, and prompt to create frames.
    • Saves the generated frames as a video using the imageio library, setting the specified frame rate (fps).
    • Logs a success message and returns 0 if the process is successful.
    • On error, logs the issue and returns 1.

    Now, let us understand the performance. But, before that let us explore the device on which we’ve performed these stress test that involves GPU & CPUs as well.

    And, here is the performance stats –

    From the above snapshot, we can clearly communicate that the GPU is 100% utilized. However, the CPU has shown a significant % of availability.

    As you can see, the first pass converts the input prompt to intermediate images within 1 min 30 sec. However, the second pass constitutes multiple hops (11 hops) on an avg 22 seconds. Overall, the application will finish in 5 minutes 36 seconds for a 10-second video clip.


    So, we’ve done it.

    You can find the detailed code at the GitHub link.

    I’ll bring some more exciting topics in the coming days from the Python verse.

    Till then, Happy Avenging! 🙂

    Enabling & Exploring Stable Defussion – Part 2

    As we’ve started explaining, the importance & usage of Stable Defussion in our previous post:

    Enabling & Exploring Stable Defussion – Part 1

    In today’s post, we’ll discuss another approach, where we built the custom Python-based SDK solution that consumes HuggingFace Library, which generates video out of the supplied prompt.

    But, before that, let us view the demo generated from a custom solution.

    Isn’t it exciting? Let us dive deep into the details.


    Let us understand basic flow of events for the custom solution –

    So, the application will interact with the python-sdk like “stable-diffusion-3.5-large” & “dreamshaper-xl-1-0”, which is available in HuggingFace. As part of the process, these libraries will load all the large models inside the local laptop that require some time depend upon the bandwidth of your internet.

    Before we even deep dive into the code, let us understand the flow of Python scripts as shown below:

    From the above diagram, we can understand that the main application will be triggered by “generateText2Video.py”. As you can see that “clsConfigClient.py” has all the necessary parameter information that will be supplied to all the scripts.

    “generateText2Video.py” will trigger the main class named “clsText2Video.py”, which then calls all the subsequent classes.

    Great! Since we now have better visibility of the script flow, let’s examine the key snippets individually.


    class clsText2Video:
        def __init__(self, model_id_1, model_id_2, output_path, filename, vidfilename, fps, force_cpu=False):
            self.model_id_1 = model_id_1
            self.model_id_2 = model_id_2
            self.output_path = output_path
            self.filename = filename
            self.vidfilename = vidfilename
            self.force_cpu = force_cpu
            self.fps = fps
    
            # Initialize in main process
            os.environ["TOKENIZERS_PARALLELISM"] = "true"
            self.r1 = cm.clsMaster(force_cpu)
            self.torch_type = self.r1.getTorchType()
            
            torch.mps.empty_cache()
            self.pipe = self.r1.getText2ImagePipe(self.model_id_1, self.torch_type)
            self.pipeline = self.r1.getImage2VideoPipe(self.model_id_2, self.torch_type)
    
            self.text2img = cti.clsText2Image(self.pipe, self.output_path, self.filename)
            self.img2vid = civ.clsImage2Video(self.pipeline)
    
        def getPrompt2Video(self, prompt):
            try:
                input_image = self.output_path + self.filename
                target_video = self.output_path + self.vidfilename
    
                if self.text2img.genImage(prompt) == 0:
                    print('Pass 1: Text to intermediate images generated!')
                    
                    if self.img2vid.genVideo(prompt, input_image, target_video, self.fps) == 0:
                        print('Pass 2: Successfully generated!')
                        return 0
                return 1
            except Exception as e:
                print(f"\nAn unexpected error occurred: {str(e)}")
                return 1

    Now, let us interpret:

    This is the initialization method for the class. It does the following:

    • Sets up configurations like model IDs, output paths, filenames, video filename, frames per second (fps), and whether to use the CPU (force_cpu).
    • Configures an environment variable for tokenizer parallelism.
    • Initializes helper classes (clsMaster) to manage system resources and retrieve appropriate PyTorch settings.
    • Creates two pipelines:
      • pipe: For converting text to images using the first model.
      • pipeline: For converting images to video using the second model.
    • Initializes text2img and img2vid objects:
      • text2img handles text-to-image conversions.
      • img2vid handles image-to-video conversions.

    This method generates a video from a text prompt in two steps:

    1. Text-to-Image Conversion:
      • Calls genImage(prompt) using the text2img object to create an intermediate image file.
      • If successful, it prints confirmation.
    2. Image-to-Video Conversion:
      • Uses the img2vid object to convert the intermediate image into a video file.
      • Includes the input image path, target video path, and frames per second (fps).
      • If successful, it prints confirmation.
    • If either step fails, the method returns 1.
    • Logs any unexpected errors and returns 1 in such cases.

                return self.pipeline

    Let us interpret:

    This function determines whether to use the Apple Silicon GPU (MPS) or the CPU:

    • If force_cpu is False and the MPS GPU is available, it sets the device to “mps” (Apple GPU) and prints a message.
    • Otherwise, it defaults to the CPU.

    This is the initializer for the clsMaster class:

    • It sets the device to either GPU or CPU using the setup_gpu function (mentioned above) based on the force_cpu flag.

    This method determines the PyTorch data type to use:

    • Checks if MPS GPU is available:
      • If available, uses torch.float16 for optimized performance.
      • If unavailable, defaults to torch.float32 and raises a warning.
    • Handles errors gracefully by defaulting to torch.float16 and printing the error.

    This method initializes a text-to-image pipeline:

    • Loads the Stable Diffusion model with the given model_id and torchType.
    • Configures it for MPS GPU or CPU, based on the device.
    • Clears the GPU cache before loading the model to optimize memory usage.
    • If an error occurs, attempts to reload the pipeline without safetensors.

    This method initializes an image-to-video pipeline:

    • Similar to getText2ImagePipe, it loads the Stable Diffusion XL Img2Img pipeline with the specified model_id and torchType.
    • Configures it for MPS GPU or CPU and clears the cache before loading.
    • On error, reloads the pipeline without additional optimization settings and prints the error.

    Let us continue this in the next post:

    Till then, Happy Avenging! 🙂

    Building solutions using LLM AutoGen in Python – Part 3

    Before we dive into the details of this post, let us provide the previous two links that precede it.

    Building solutions using LLM AutoGen in Python – Part 1

    Building solutions using LLM AutoGen in Python – Part 2

    For, reference, we’ll share the demo before deep dive into the actual follow-up analysis in the below section –


    In this post, we will understand the initial code generated & then the revised code to compare them for a better understanding of the impact of revised prompts.

    But, before that let us broadly understand the communication types between the agents.

    • Agents InvolvedAgent1Agent2
    • Flow:
      • Agent1 sends a request directly to Agent2.
      • Agent2 processes the request and sends the response back to Agent1.
    • Use Case: Simple query-response interactions without intermediaries.
    • Agents InvolvedUserAgentMediatorSpecialistAgent1SpecialistAgent2
    • Flow:
      • UserAgent sends input to Mediator.
      • Mediator delegates tasks to SpecialistAgent1 and SpecialistAgent2.
      • Specialists process tasks and return results to Mediator.
      • Mediator consolidates results and sends them back to UserAgent.
    • Agents InvolvedBroadcasterAgentAAgentBAgentC
    • Flow:
      • Broadcaster sends a message to multiple agents simultaneously.
      • Agents that find the message relevant (AgentAAgentC) acknowledge or respond.
    • Use Case: System-wide notifications or alerts.
    • Agents InvolvedSupervisorWorker1Worker2
    • Flow:
      • Supervisor assigns tasks to Worker1 and Worker2.
      • Workers execute tasks and report progress back to Supervisor.
    • Use Case: Task delegation in structured organizations.
    • Agents InvolvedPublisherSubscriber1Topic
    • Flow:
      • Publisher publishes an event or message to a Topic.
      • Subscriber1, who is subscribed to the Topic, receives the event.
    • Use Case: Decoupled systems where publishers and subscribers do not need direct knowledge of each other.
    • Agents InvolvedTriggerEventReactiveAgentNextStep
    • Flow:
      • An event occurs (TriggerEvent).
      • ReactiveAgent detects the event and acts.
      • The action leads to the NextStep in the process.
    • Use Case: Systems that need to respond to asynchronous events or changes in the environment.

    Now, let us remember the prompt refinement that we’ve done (We’ve already posted that in our last post as well) –

    I want to place the snake within the boundary of the visual wall & it should bounce each wall & then hit the target. And, it should increase the size. And, every time when it hits the target it will increase the score by 10. And, the application will run for 2 minutes, which will be displayed on the screen. This will exit once 2 minute is over.

    gameLoop()
    

    Now, let us understand the difference here –

    The first program is a snake game controlled by arrow keys that end if the Snake hits a wall or itself. The second game uses mouse clicks for control, bounces off walls instead of ending, includes a 2-minute timer, and displays the remaining time.

    So, we’ve done it. 🙂

    You can find the detailed code in the following Github link.


    I’ll bring some more exciting topics in the coming days from the Python verse.

    Till then, Happy Avenging! 🙂

    Building & deploying a RAG architecture rapidly using Langflow & Python

    I’ve been looking for a solution that can help deploy any RAG solution involving Python faster. It would be more effective if an available UI helped deliver the solution faster. And, here comes the solution that does exactly what I needed – “LangFlow.”

    Before delving into the details, I strongly recommend taking a look at the demo. It’s a great way to get a comprehensive understanding of LangFlow and its capabilities in deploying RAG architecture rapidly.

    Demo

    This describes the entire architecture; hence, I’ll share the architecture components I used to build the solution.

    To know more about RAG-Architecture, please refer to the following link.

    As we all know, we can parse the data from the source website URL (in this case, I’m referring to my photography website to extract the text of one of my blogs) and then embed it into the newly created Astra DB & new collection, where I will be storing the vector embeddings.

    As you can see from the above diagram, the flow that I configured within 5 minutes and the full functionality of writing a complete solution (underlying Python application) within no time that extracts chunks, converts them into embeddings, and finally stores them inside the Astra DB.

    Now, let us understand the next phase, where, based on the ask from a chatbot, I need to convert that question into Vector DB & then find the similarity search to bring the relevant vectors as shown below –

    You need to configure this entire flow by dragging the necessary widgets from the left-side panel as marked in the Blue-Box shown below –

    For this specific use case, we’ve created an instance of Astra DB & then created an empty vector collection. Also, we need to ensure that we generate the API-Key & and provide the right roles assigned with the token. After successfully creating the token, you need to copy the endpoint, token & collection details & paste them into the desired fields of the Astra-DB components inside the LangFlow. Think of it as a framework where one needs to provide all the necessary information to build & run the entire flow successfully.

    Following are some of the important snapshots from the Astra-DB –

    Step – 1

    Step – 2

    Once you run the vector DB population, this will insert extracted text & then convert it into vectors, which will show in the following screenshot –

    You can see the sample vectors along with the text chunks inside the Astra DB data explorer as shown below –

    Some of the critical components are highlighted in the Blue-box which is important for us to monitor the vector embeddings.

    Now, here is how you can modify the current Python code of any available widgets or build your own widget by using the custom widget.

    The first step is to click the code button highlighted in the Red-box as shown below –

    The next step is when you click that button, which will open the detailed Python code representing the entire widget build & its functionality. This button is the place where you can add, modify, or keep it as it is depending upon your need, which will shown below –

    Once one builds the entire solution, you must click the final compile button (shown in the red box), which will eventually compile all the individual widgets. However, you can build the compile button for the individual widgets as soon as you make the solution. So you can pinpoint any potential problems at that very step.

    Let us understand one sample code of a widget. In this case, we will take vector embedding insertion into the Astra DB. Let us see the code –

    Method: build_config:

    • This method defines the configuration options for the component.
    • Each configuration option includes a display_name and info, which provides details about the option.
    • Some options are marked as advanced, indicating they are optional and more complex.

    Method: build:

    • This method is used to create an instance of the Astra DB Vector Store.
    • It takes several parameters, including embedding, token, api_endpoint, collection_name, and various optional parameters.
    • It converts the setup_mode string to an enum value.
    • If inputs are provided, they are converted to a format suitable for storing in the vector store.
    • Depending on whether inputs are provided, a new vector store from documents can be created, or an empty vector store can be initialized with the given configurations.
    • Finally, it returns the created vector store instance.

    Building a real-time Gen AI Improvement Matrices (GAIIM) using Python, UpTrain, Open AI & React

    How does the RAG work better for various enterprise-level Gen AI use cases? What needs to be there to make the LLM model work more efficiently & able to check the response & validate their response, including the bias, hallucination & many more?

    This is my post (after a slight GAP), which will capture and discuss some of the burning issues that many AI architects are trying to explore. In this post, I’ve considered a newly formed AI start-up from India, which developed an open-source framework that can easily evaluate all the challenges that one is facing with their LLMs & easily integrate with your existing models for better understanding including its limitations. You will get plenty of insights about it.

    But, before we dig deep, why not see the demo first –

    Isn’t it exciting? Let’s deep dive into the flow of events.


    Let’s explore the broad-level architecture/flow –

    Let us understand the steps of the above architecture. First, our Python application needs to trigger and enable the API, which will interact with the Open AI and UpTrain AI to fetch all the LLM KPIs based on the input from the React app named “Evaluation.”

    Once the response is received from UpTrain AI, the Python application then organizes the results in a better readable manner without changing the core details coming out from their APIs & then shares that back with the react interface.

    Let’s examine the react app’s sample inputs to better understand the input that will be passed to the Python-based API solution, which is wrapper capability to call multiple APIs from the UpTrain & then accumulate them under one response by parsing the data & reorganizing the data with the help of Open AI & sharing that back.

    Highlighted in RED are some of the critical inputs you need to provide to get most of the KPIs. And, here are the sample text inputs for your reference –

    Q. Enter input question.
    A. What are the four largest moons of Jupiter?
    Q. Enter the context document.
    A. Jupiter, the largest planet in our solar system, boasts a fascinating array of moons. Among these, the four largest are collectively known as the Galilean moons, named after the renowned astronomer Galileo Galilei, who first observed them in 1610. These four moons, Io, Europa, Ganymede, and Callisto, hold significant scientific interest due to their unique characteristics and diverse geological features.
    Q. Enter LLM response.
    A. The four largest moons of Jupiter, known as the Galilean moons, are Io, Europa, Ganymede, and Marshmello.
    Q. Enter the persona response.
    A. strict and methodical teacher
    Q. Enter the guideline.
    A. Response shouldn’t contain any specific numbers
    Q. Enter the ground truth.
    A. The Jupiter is the largest & gaseous planet in the solar system.
    Q. Choose the evaluation method.
    A. llm

    Once you fill in the App should look like this –

    Once you fill in, the app should look like the below screenshot –


    Let us understand the sample packages that are required for this task.

    pip install Flask==3.0.3
    pip install Flask-Cors==4.0.0
    pip install numpy==1.26.4
    pip install openai==1.17.0
    pip install pandas==2.2.2
    pip install uptrain==0.6.13

    Note that, we’re not going to discuss the entire script here. Only those parts are relevant. However, you can get the complete scripts in the GitHub repository.

    def askFeluda(context, question):
        try:

            conversation_history = []
    
            # Add the new message to the conversation history
            conversation_history.append(prompt_text)

                temperature=0.3,  # Adjust for creativity. Lower values make responses more focused and deterministic

            chat_response = response.choices[0].message.content
    
            # Print the generated response text
            return chat_response.strip()
        except Exception as e:
            return f"An error occurred: {str(e)}"

    This function will ask the supplied questions with contexts or it will supply the UpTrain results to summarize the JSON into more easily readable plain texts. For our test, we’ve used “gpt-3.5-turbo”.

    def evalContextRelevance(question, context, resFeluda, personaResponse):
        try:
            data = [{
                'question': question,
                'context': context,
                'response': resFeluda
            }]
    
            results = eval_llm.evaluate(
                data=data,
                checks=[Evals.CONTEXT_RELEVANCE, Evals.FACTUAL_ACCURACY, Evals.RESPONSE_COMPLETENESS, Evals.RESPONSE_RELEVANCE, CritiqueTone(llm_persona=personaResponse), Evals.CRITIQUE_LANGUAGE, Evals.VALID_RESPONSE, Evals.RESPONSE_CONCISENESS]
            )

        except Exception as e:
            x = str(e)
    
            return x

    The above methods initiate the model from UpTrain to get all the stats, which will be helpful for your LLM response. In this post, we’ve captured the following KPIs –

    - Factual Accuracy Explanation
    - Guideline Adherence Explanation

    Let us see some of the screenshots of the test run –


    So, we’ve done it.

    I’ll bring some more exciting topics in the coming days from the Python verse.

    Till then, Happy Avenging! 🙂

    Enabling & Exploring Stable Defussion – Part 1

    This new solution will evaluate the power of Stable Defussion, which is created solutions as we progress & refine our prompt from scratch by using Stable Defussion & Python. This post opens new opportunities for IT companies & business start-ups looking to deliver solutions & have better performance compared to the paid version of Stable Defussion AI’s API performance. This project is for the advanced Python, Stable Defussion for data Science Newbies & AI evangelists.

    In a series of posts, I’ll explain and focus on the Stable Defussion API and custom solution using the Python-based SDK of Stable Defussion.

    But, before that, let us view the video that it generates from the prompt by using the third-party API:

    Prompt to Video

    And, let us understand the prompt that we supplied to create the above video –

    Isn’t it exciting?

    However, I want to stress this point: the video generated by the Stable Defusion (Stability AI) API was able to partially apply the animation effect. Even though the animation applies to the cloud, It doesn’t apply the animation to the wave. But, I must admit, the quality of the video is quite good.


    Let us understand the code and how we run the solution, and then we can try to understand its performance along with the other solutions later in the subsequent series.

    As you know, we’re exploring the code base of the third-party API, which will actually execute a series of API calls that create a video out of the prompt.

    Let us understand some of the important snippet –

    class clsStabilityAIAPI:
        def __init__(self, STABLE_DIFF_API_KEY, OUT_DIR_PATH, FILE_NM, VID_FILE_NM):
            self.STABLE_DIFF_API_KEY = STABLE_DIFF_API_KEY
            self.OUT_DIR_PATH = OUT_DIR_PATH
            self.FILE_NM = FILE_NM
            self.VID_FILE_NM = VID_FILE_NM
    
        def delFile(self, fileName):
            try:
                # Deleting the intermediate image
                os.remove(fileName)
    
                return 0 
            except Exception as e:
                x = str(e)
                print('Error: ', x)
    
                return 1
    
        def generateText2Image(self, inputDescription):
            try:
                STABLE_DIFF_API_KEY = self.STABLE_DIFF_API_KEY
                fullFileName = self.OUT_DIR_PATH + self.FILE_NM
                
                if STABLE_DIFF_API_KEY is None:
                    raise Exception("Missing Stability API key.")

                else:
                    raise Exception(str(response.json()))
                
            except Exception as e:
                x = str(e)
                print('Error: ', x)
    
                return 1

    Now, let us understand the code –

    This function is called when an object of the class is created. It initializes four properties:

    • STABLE_DIFF_API_KEY: the API key for Stability AI services.
    • OUT_DIR_PATH: the folder path to save files.
    • FILE_NM: the name of the generated image file.
    • VID_FILE_NM: the name of the generated video file.

    This function deletes a file specified by fileName.

    • If successful, it returns 0.
    • If an error occurs, it logs the error and returns 1.

    This function generates an image based on a text description:

    • Sends a request to the Stability AI text-to-image endpoint using the API key.
    • Saves the resulting image to a file.
    • Returns the file’s path on success or 'N/A' if an error occurs.

    This function uploads an image to create a video in its first phase:

    • Sends the image to Stability AI’s image-to-video endpoint.
    • Logs the response and extracts the id (generation ID) for the next phase.
    • Returns the id if successful or 'N/A' on failure.

    This function retrieves the video created in the second phase using the genId:

    • Checks the video generation status from the Stability AI endpoint.
    • If complete, saves the video file and returns 0.
    • If still processing, returns 5.
    • Logs and returns 1 for any errors.

    As you can see, the code is pretty simple to understand & we’ve taken all the necessary actions in case of any unforeseen network issues or even if the video is not ready after our job submission in the following lines of the main calling script (generateText2VideoAPI.py) –

    waitTime = 10
    time.sleep(waitTime)
    
    # Failed case retry
    retries = 1
    success = False
    
    try:
        while not success:
            try:
                z = r1.image2VideoPassTwo(gID)
            except Exception as e:
                success = False
    
            if z == 0:
                success = True
            else:
                wait = retries * 2 * 15
                str_R1 = "retries Fail! Waiting " + str(wait) + " seconds and retrying!"
    
                print(str_R1)
    
                time.sleep(wait)
                retries += 1
    
            # Checking maximum retries
            if retries >= maxRetryNo:
                success = True
                raise  Exception
    except:
        print()

    And, let us see how the run looks like –

    Let us understand the CPU utilization –

    As you can see, CPU utilization is minimal since most tasks are at the API end.


    So, we’ve done it. 🙂

    We’ll continue to discuss this topic in the upcoming post.

    I’ll bring some more exciting topics in the coming days from the Python verse.

    Till then, Happy Avenging! 🙂

    Building a real-time streamlit app by consuming events from Ably channels

    I’ll bring an exciting streamlit app that will reflect the real-time dashboard by consuming all the events from the Ably channel.

    One more time, I’ll be utilizing my IoT emulator that will feed the real-time events based on the user inputs to the Ably channel, which will be subscribed to by the Streamlit-based app.

    However, I would like to share the run before we dig deep into this.


    Demo

    Isn’t this exciting? How we can use our custom-built IoT emulator & capture real-time events to Ably Queue, then transform those raw events into more meaningful KPIs? Let’s deep dive then.

    Let’s explore the broad-level architecture/flow –

    As you can see, the green box is a demo IoT application that generates events & pushes them into the Ably Queue. At the same time, the streamlit-based Dashboard app consumes the events & transforms them into more meaningful metrics.

    Let us understand the sample packages that are required for this task.

    pip install ably==2.0.3
    pip install numpy==1.26.3
    pip install pandas==2.2.0
    pip install plotly==5.19.0
    pip install requests==2.31.0
    pip install streamlit==1.30.0
    pip install streamlit-autorefresh==1.0.1
    pip install streamlit-echarts==0.4.0

    Since this is an extension to our previous post, we’re not going to discuss other scripts, which we’ve already discussed over there. Instead, we will talk about the enhanced scripts & the new scripts that are required for this use case.

    1. app.py (This script will consume real-time streaming data coming out from a hosted API source using another popular third-party service named Ably. Ably mimics the pub sub-streaming concept, which might be extremely useful for any start-up. This will then translate into many meaningful KPIs in a streamlit-based dashboard app.)

    Note that, we’re not going to discuss the entire script here. Only those parts are relevant. However, you can get the complete scripts in the GitHub repository.

    def createHumidityGauge(humidity_value):
        fig = go.Figure(go.Indicator(
            mode = "gauge+number",
            value = humidity_value,
            domain = {'x': [0, 1], 'y': [0, 1]},
            title = {'text': "Humidity", 'font': {'size': 24}},
            gauge = {
                'axis': {'range': [None, 100], 'tickwidth': 1, 'tickcolor': "darkblue"},
                'bar': {'color': "darkblue"},
                'bgcolor': "white",
                'borderwidth': 2,
                'bordercolor': "gray",
                'steps': [
                    {'range': [0, 50], 'color': 'cyan'},
                    {'range': [50, 100], 'color': 'royalblue'}],
                'threshold': {
                    'line': {'color': "red", 'width': 4},
                    'thickness': 0.75,
                    'value': humidity_value}
            }
        ))
    
        fig.update_layout(height=220, paper_bgcolor = "white", font = {'color': "darkblue", 'family': "Arial"}, margin=dict(t=0, l=5, r=5, b=0))
    
        return fig

    The above function creates a customized humidity gauge that visually represents a given humidity value, making it easy to read and understand at a glance.

    This code defines a function createHumidityGauge that creates a visual gauge (like a meter) to display a humidity value. Here’s a simple breakdown of what it does:

    1. Function Definition: It starts by defining a function named createHumidityGauge that takes one parameter, humidity_value, which is the humidity level you want to display on the gauge.
    2. Creating the Gauge: Inside the function, it creates a figure using Plotly (a plotting library) with a specific type of chart called an Indicator. This Indicator is set to display in “gauge+number” mode, meaning it shows both a gauge visual and the numeric value of the humidity.
    3. Setting Gauge Properties:
      • The value is set to the humidity_value parameter, so the gauge shows this humidity level.
      • The domain sets the position of the gauge on the plot, which is set to fill the available space ([0, 1] for both x and y axes).
      • The title is set to “Humidity” with a font size of 24, labeling the gauge.
      • The gauge section defines the appearance and behavior of the gauge, including:
        • An axis that goes from 0 to 100 (assuming humidity is measured as a percentage from 0% to 100%).
        • The color and style of the gauge’s bar and background.
        • Colored steps indicating different ranges of humidity (cyan for 0-50% and royal blue for 50-100%).
        • A threshold line that appears at the value of the humidity, marked in red to stand out.
    4. Finalizing the Gauge Appearance: The function then updates the layout of the figure to set its height, background color, font style, and margins to make sure the gauge looks nice and is visible.
    5. Returning the Figure: Finally, the function returns the fig object, which is the fully configured gauge, ready to be displayed.

    Other similar functions will repeat the same steps.

    def createTemperatureLineChart(data):
        # Assuming 'data' is a DataFrame with a 'Timestamp' index and a 'Temperature' column
        fig = px.line(data, x=data.index, y='Temperature', title='Temperature Vs Time')
        fig.update_layout(height=270)  # Specify the desired height here
        return fig

    The above function takes a set of temperature data indexed by timestamp and creates a line chart that visually represents how the temperature changes over time.

    This code defines a function “createTemperatureLineChart” that creates a line chart to display temperature data over time. Here’s a simple summary of what it does:

    1. Function Definition: It starts with defining a function named createTemperatureLineChart that takes one parameter, data, which is expected to be a DataFrame (a type of data structure used in pandas, a Python data analysis library). This data frame should have a ‘Timestamp’ as its index (meaning each row represents a different point in time) and a ‘Temperature’ column containing temperature values.
    2. Creating the Line Chart: The function uses Plotly Express (a plotting library) to create a line chart with the following characteristics:
      • The x-axis represents time, taken from the DataFrame’s index (‘Timestamp’).
      • The y-axis represents temperature, taken from the ‘Temperature’ column in the DataFrame.
      • The chart is titled ‘Temperature Vs Time’, clearly indicating what the chart represents.
    3. Customizing the Chart: It then updates the layout of the chart to set a specific height (270 pixels) for the chart, making it easier to view.
    4. Returning the Chart: Finally, the function returns the fig object, which is the fully prepared line chart, ready to be displayed.

    Similar functions will repeat for other KPIs.

        st.sidebar.header("KPIs")
        selected_kpis = st.sidebar.multiselect(
            "Select KPIs", options=["Temperature", "Humidity", "Pressure"], default=["Temperature"]
        )

    The above code will create a sidebar with drop-down lists, which will show the KPIs (“Temperature”, “Humidity”, “Pressure”).

    # Split the layout into columns for KPIs and graphs
        gauge_col, kpi_col, graph_col = st.columns(3)

    1. The code begins by splitting the Streamlit web page layout into three columns to separately display Key Performance Indicators (KPIs), gauges, and graphs.
    2. It sets up an auto-refresh feature with a 7-second interval, ensuring the data displayed is regularly updated without manual refreshes.
    3. Real-time data is fetched using a function called getData, which takes unspecified parameters var1 and DInd.
    4. A CSS style is injected into the Streamlit page to adjust the margin of Echarts elements, which may be used to improve the visual layout of the page.
    5. A container for gauges is created at the top of the page, with three columns inside it dedicated to displaying humidity, temperature, and pressure gauges.
    6. Each gauge (humidity, temperature, and pressure) is created by rounding the last value from the fetched data to two decimal places and then visualized using respective functions that create Plotly gauge charts.
    7. Below the gauges, another container is set up for displaying the latest readings and their corresponding graphs in a side-by-side layout, using two columns.
    8. The left column under “Latest Readings” displays the latest values for selected KPIs (temperature, humidity, pressure) as metrics.
    9. In the right column, for each selected KPI, a line chart is created using data with timestamps as indices and displayed using Plotly charts, allowing for a visual trend analysis.
    10. This structured approach enables a dynamic and interactive dashboard within Streamlit, offering real-time insights into temperature, humidity, and pressure with both numeric metrics and graphical trends, optimized for regular data refreshes and user interactivity.
