My personal repo to convert models from Lora to huggingface/ggml/gptq 4bit so I can run them in normal text-webui and llama.cpp

How do we do this?

1. lora -> hf
   • tloen/alpaca-lora/export_hf_checkpoint.py
2. hf -> 4bit
   • using GPTQ-for-LLaMa/llama.py CUDA_VISIBLE_DEVICES=0 python llama.py ./llama-hf/llama-7b c4 --wbits 4 --true-sequential --act-order --groupsize 128 --save llama7b-4bit-128g.pt

3. and to ggml
   • llama.cpp/convert-pth-to-ggml.py

TODO

• lora -> hf
• hf -> 4bit
• hf -> ggml

setup env

conda create -n textgen4 python=3.10.9 -y
conda activate textgen4
mamba install pytorch torchvision torchaudio pytorch-cuda=11.7 cudatoolkit-dev==11.7  cudatoolkit=11.7 -c pytorch -c nvidia  -c conda-forge  -y
pip install -r requirements.txt
pip install git+https://github.com/sterlind/GPTQ-for-LLaMa.git@lora_4bit

OK I need lots more mem... copy to ec2

rsync -a . alpaca:/home/ubuntu/alpaca_convert_mjc --exclude=models
