alpaca_convert/README.md

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. 4bit -> ggml
   • llama.cpp/convert-pth-to-ggml.py

TODO

• lora -> hf
  • test this
• hf -> 4bit
• 4bit to -> ggml
• test perplexity on llama and alpaca type prompts too! maybe use eluther evals
