Mimo-1B 0.1.2

Fine-tuning toolkit for the `deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B` model using QLoRA on macOS systems with limited RAM (~8GB). Includes conversion to GGUF format for usage with Ollama and LM Studio.

Mimo LLM Project - Fine-tuning and GGUF Export

This project provides the necessary scripts and instructions to fine-tune the deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B model using QLoRA on a macOS system with limited RAM (~8GB), convert it to the GGUF format, and make it ready for use with Ollama and LM Studio.

Objective

• Base Model: deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B from Hugging Face.
• Fine-tuning Method: QLoRA for efficient adaptation on low-resource hardware.
• Dataset: yahma/alpaca-cleaned (public text dataset).
• RAM Optimization: Tuned for ~8GB RAM.
• Output Format: GGUF (quantized 4-bit or 8-bit).
• Final Model Name: Mimo
• Attribution: "Créé par ABDESSEMED Mohamed Redha"
• Compatibility: Ollama and LM Studio.

Setup Instructions

1. Create a Python virtual environment (recommended):

   python3 -m venv venv
   source venv/bin/activate
   

2. Install dependencies:

   pip install -r requirements.txt
   

   Note: Ensure you have the correct PyTorch version installed for your macOS system (CPU or Metal/MPS for Apple Silicon). Refer to the official PyTorch website for installation instructions. Or ```pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu

For Apple Silicon (MPS) : ```pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu

Fine-tuning (QLoRA)

The train_qlora.py script handles the fine-tuning process. It loads the base model, applies 4-bit quantization and QLoRA, and trains on the specified dataset.

• To start training:

  python train_qlora.py
  

• Output: The fine-tuned model adapters will be saved in the outputs/mimo-qlora directory.
• RAM Optimization: The script is configured with per_device_train_batch_size=1 and gradient_accumulation_steps=8 to manage memory usage. max_steps is set to 100 for a quick example; adjust as needed for longer training. gradient_checkpointing=True is also enabled for further memory savings.

Conversion to GGUF

The export_to_gguf.py script first merges the QLoRA adapters into the base model and saves it in Hugging Face format. It then provides instructions on how to convert this merged model into the GGUF format using the llama.cpp conversion tools.

1. Run the export script:

   python export_to_gguf.py
   

   This will save the merged Hugging Face model in gguf_model/merged_hf_model/ and print instructions for the GGUF conversion.

2. Convert to GGUF using llama.cpp: Follow these steps after running export_to_gguf.py:

   • Ensure you have llama-cpp-python installed:

     pip install llama-cpp-python
     

   • Navigate to your llama.cpp directory (you might need to clone it from GitHub if you don't have it).
   • Run the convert.py script from llama.cpp, pointing it to your saved Hugging Face model directory and specifying the desired quantization type.

   Example command:

   # Assuming you are in the llama.cpp directory and your merged model is at /Users/mohamed/Downloads/mac_ai_project/gguf_model/merged_hf_model
   # And you want to quantize to 4-bit (q4_0)
   python convert.py /Users/mohamed/Downloads/mac_ai_project/gguf_model/merged_hf_model --outfile /Users/mohamed/Downloads/mac_ai_project/gguf_model/Mimo.gguf --outtype q4_0
   

   • You can choose different quantization types like q8_0 for 8-bit, f16 for float16, etc. q4_0 is a good balance for 4-bit.

• Output: The final GGUF model will be saved as gguf_model/Mimo.gguf.

Usage

Ollama

1. Create a Modelfile: Create a file named Modelfile (no extension) in the same directory as your Mimo.gguf file with the following content:

   FROM ./Mimo.gguf
   
   TEMPLATE """{{ .System }}
   {{- if .Prompt }}
   USER: {{ .Prompt }}
   ASSISTANT: {{ .Response }}
   {{- end }}"""
   
   PARAMETER stop "USER:"
   PARAMETER stop "ASSISTANT:"
   PARAMETER temperature 0.7
   PARAMETER top_k 40
   PARAMETER top_p 0.9
   PARAMETER num_ctx 2048
   PARAMETER repeat_penalty 1.1
   

   Adjust num_ctx and other parameters as needed.

2. Import into Ollama: Navigate to the directory containing Mimo.gguf and your Modelfile in your terminal, then run:

   ollama create mimo -f ./Modelfile
   

   You can then interact with the model using ollama run mimo.

LM Studio

1. Open LM Studio.
2. Go to the "Local Server" tab or the "AI Models" tab.
3. Click the folder icon to browse for models.
4. Navigate to the gguf_model/ directory and select Mimo.gguf.
5. The model should load, and you can start chatting.
