Fine-Tuning Meta's Llama 3 8B for IMPRESSIVE Deployment on Edge Devices - OUTSTANDING Results! 

I'm still struggling. There is a lot of advertisements and explanations, tutorials of other tools which I don't care at all. I want to learn about fine tuning, it should be all about some python code and whatever libraries used. People can use all kinds of other tools to support the development, if they cannot open an excel file or know where to write their python code, they shouldn't be in the AI business at all.

Thanks for your question and for watching the video. I'm glad you found it informative! Your approach largely depends on your use case and the kind of insights you're looking to derive from your data. Generally, you're going to want to follow these steps to train a model with complex data: Decide how you plan to interact with the model. For instance, maybe you're doing text generation; or natural language understanding tasks like sentiment analysis, named entity recognition and question answering; or text summarization; or domain-specific queries like legal, medical or corporate. Choose a model that has high benchmarks for the specific requirements of your task, the nature of your data and the desired output format. A model is more likely to train well if the base model's capabilities are already very strong for the task you intend to use it for. Consider factors like model performance, computational resources, and the availability of pre-trained weights for your specific domain or language. Prepare and preprocess your dataframes, removing/filling missing values, encoding variables numerically and normalizing the data. The cleaner the data, the better the training will be. Split the data into a training set and validation set. The validation set will be data you haven't trained the model on to see how the model performs with unseen data. Fine-tune with your dataset, test the model out, then iterate on the process by tweaking data, adding more data, trying different training parameters, even trying different models. Hope this helps guide you in your endeavor!

Thank you so much for the kind words and for subscribing, I really appreciate it! I'm so glad you found the video helpful in explaining how to fine-tune LLaMA 3 and run it on your own device. It's a fascinating topic and technology with a lot of potential. I'm looking forward to sharing more content on large language models and AI that you'll hopefully find just as valuable. Stay tuned!

Except for the download, which I sped up significantly, everything in terminal was shown in real time. The demo was done on a MacBook Pro M3 Pro Max. YMMV with other hardware.

Thanks for your question! When scaling up from just 30 records to 1000 question-answer pairs, you'll likely need to adjust several parameters to accommodate the increased dataset size and try to improve the fine-tuning. Here are some key parameters to consider updating: * Batch size: With a larger dataset, you may want to increase the batch size to process more examples per iteration. This can help improve training efficiency. * Learning rate: You might need to adjust the learning rate. With more data, you could potentially use a slightly higher learning rate, but be careful not to set it too high. * Number of epochs: With more data, you might need fewer epochs to reach convergence. Monitor the training and validation loss to determine the optimal number of epochs. * LoRA rank: You might consider increasing the LoRA rank to allow for more capacity in the adapted layers, given the larger dataset. * Warmup steps: Adjust the number of warmup steps proportionally to the increased dataset size. Weight decay: You might need to adjust the weight decay to prevent overfitting on the larger dataset. * Gradient accumulation steps: If memory is a constraint, you might need to use gradient accumulation to effectively increase the batch size. * Evaluation strategy: Consider evaluating more frequently with the larger dataset. As for specific values, it's hard to provide exact numbers, as they're going to differ between use cases, actual data, hardware, and desired outcomes. But, here are some general guidelines: * Batch size: Try increasing to 16 or 32, depending on your GPU memory. * Learning rate: Start with 2e-4 to 5e-4 and adjust based on training performance. * Number of epochs: Start with 3-5 epochs and adjust based on convergence. * LoRA rank: Consider increasing to 16 or 32. * Warmup steps: 10% of the total training steps is a good starting point. * Weight decay: Start with 0.01 and adjust as needed. * Gradient accumulation steps: Start with 4 or 8 and adjust based on your hardware capabilities. * Evaluation strategy: Consider evaluating every 500 or 1000 steps. These are just starting points. Every use case is different. You'll need to experiment. You might be able to use techniques like learning rate finders or hyperparameter tuning to optimize for your specific case. Good luck! Scott

Hi! Thanks for your question. When working with a 4-bit quantized version of Llama 3 7B using LoRA adaptation layers and PEFT, it's not uncommon to see performance changes as you add more data. This is especially true given the constraints of training in Colab on an A100. The issue you're experiencing could be due to several factors: Quantization effects: 4-bit quantization, while efficient, can sometimes lead to loss of precision, which might become more apparent with more diverse data. LoRA adaptation: The low-rank adaptation might need adjustment as your dataset grows. The rank or alpha parameters might need tuning. PEFT limitations: While PEFT is great for efficient fine-tuning, it might struggle to capture more complex patterns as your dataset expands. Data quality and consistency: Ensure the new data aligns well with your original dataset and task objective. Limited model capacity: Despite Llama 3 7B being a large model, the quantization and adaptation techniques might limit its capacity to absorb significant new information without losing previous learning. To address this: Try adjusting your LoRA parameters (rank, alpha) to allow for more capacity. Experiment with different learning rates or training durations. Consider using a higher bit quantization if possible, though this might be constrained by Colab's resources. Ensure your new data is well-preprocessed and consistent with your original dataset. You might need to balance between the amount of new data added and the model's capacity to learn from it given the constraints. Remember, fine-tuning large language models, especially with techniques like quantization and PEFT, often requires iterative experimentation to find the right balance. Keep monitoring your performance metrics and adjusting your approach accordingly. Good luck! Scott

@@scott_ingram are you intrested to colab with my company? Regarding this Fine tuning

Great suggestion! I will look into that.

I haven't personally fine-tuned models for languages other than English, but Llama 3 is one of the best available multilingual open source models.

Good question. I am about to try that. I think you need an Ampere architecture on the GPU - (A100 or RTX 3090). Scott, thanks for a great video.

Ampere architecture for BF16 as opposed to F16 as per Scott's explanation in the video.

Thanks for your question! The notebook is designed to do the training on Colab, but you can run it locally for training if you have compatible hardware; I haven't tested it locally though. The RTX3090 does support brain float. Install python, then set up a virtual environment: python3 -m venv venv source venv/bin/activate Next, install and start the Jupyter notebook service: pip install jupyter jupyter notebook --kernel_name=python3 That will run a local jupyter notebook service and connect to a Python 3 kernel. Then, test GPU availability: import torch print(torch.cuda.is_available()) device = torch.device("cuda" if torch.cuda.is_available() else "cpu") print(f"Using device: {device}") Here's how you would create a tensor with pytorch on the RTX 3090 and tell it to use brain float: tensor = torch.randn(1024, 1024, dtype=torch.bfloat16) Some cells in the notebook won't run correctly, such as the first cell that sets up text wrapping (this cell is not relevant for training); that's designed for Colab specifically. There may be other compatibility issues, but I haven't tested it running locally. This should get you started to see whether your GPU could potentially work. Let me know how it works out!

@@scott_ingram Id really like to get some ai agents running locally on a self hosted model. Im hoping two rtx 3090 can combine just via PCI and load a full 70b model.

Search für Google colab. U Clan use there gpu

Thanks for your question! It sounds like you want to clean the dataset and then use it to fine-tune a model before you use it for inference. This is because if you use grammatically bad data for training, you're going to get a model that dutifully responds with bad grammar. Fixing the grammar from a model's response means that you may already have lost some context before you even get to post-processing, although it can be done programmatically. That approach has many problems. Instead, I would suggest using a large language model to clean the dataset: Preprocess the Dataset: Go through each question-answer pair in the dataset. Use a model like GPT-3.5 or GPT-4 to correct the grammar of each answer. Design a prompt for grammar correction: Create a prompt that instructs the model to correct grammar while preserving meaning. Run batch cleaning: Process the dataset in batches to speed up the cleaning process. Here's a short example of how you might implement this using the OpenAI API (with API key): ```python import openai import pandas as pd openai.api_key = 'your-api-key' def correct_grammar(text): response = openai.ChatCompletion.create( model="gpt-3.5-turbo", messages=[ {"role": "system", "content": "You are a helpful assistant that corrects grammar while preserving the original meaning."}, {"role": "user", "content": f"Correct the grammar of the following text, maintaining its original meaning: '{text}'"} ] ) return response.choices[0].message['content'] # Load your dataset df = pd.read_csv('your_dataset.csv') # Apply grammar correction to the 'answer' column df['corrected_answer'] = df['answer'].apply(correct_grammar) # Save the corrected dataset df.to_csv('corrected_dataset.csv', index=False) ``` Here are the advantages to this approach: * Consistency: It ensures a uniform level of grammatical correctness across the dataset. * Meaning Preservation: By instructing the model to maintain the original meaning, you reduce the risk of altering the content. * Efficiency: You can process a large number of entries quickly. * Flexibility: You can adjust the prompt to focus on specific aspects of grammar or style as needed. After cleaning the dataset this way, you can then use it with a fine-tuning process on the grammatically correct data (or whatever your use case prescribes). You should end up with a model that produces more grammatically correct output so you can avoid post-processing steps. Hope this helps! Scott
