# Koala: A Dialogue Model for Academic Research |
|
This repo contains the weights of the Koala 7B model produced at Berkeley. It is the result of combining the diffs from https://huggingface.co/young-geng/koala with the original Llama 7B model. |
|
|
|
This version has then been quantized to 4-bit using [GPTQ-for-LLaMa](https://github.com/qwopqwop200/GPTQ-for-LLaMa). |
|
|
|
## Other Koala repos |
|
|
|
I have also made these other Koala models available: |
|
* [GPTQ quantized 4bit 13B model in `pt` and `safetensors` formats](https://huggingface.co/TheBloke/koala-13B-GPTQ-4bit-128g) |
|
* [Unquantized 13B model in HF format](https://huggingface.co/TheBloke/koala-13B-HF) |
|
* [Unquantized 7B model in HF format](https://huggingface.co/TheBloke/koala-7B-HF) |
|
* [Unquantized 7B model in GGML format for llama.cpp](https://huggingface.co/TheBloke/koala-7b-ggml-unquantized) |
|
|
|
## Quantization method |
|
|
|
This GPTQ model was quantized using [GPTQ-for-LLaMa](https://github.com/qwopqwop200/GPTQ-for-LLaMa) with the following command: |
|
``` |
|
python3 llama.py /content/koala-7B-HF c4 --wbits 4 --true-sequential --act-order --groupsize 128 --save /content/koala-7B-4bit-128g.pt |
|
python3 llama.py /content/koala-7B-HF c4 --wbits 4 --true-sequential --act-order --groupsize 128 --save_safetensors /content/koala-7B-4bit-128g.safetensors |
|
``` |
|
|
|
I created this model using the latest Triton branch of GPTQ-for-LLaMa but it can be loaded with the CUDA branch also. |
|
|
|
## Provided files |
|
|
|
I have provided both a `pt` and `safetensors` file. Either should work. |
|
|
|
If both are present in the model directory for text-generation-webui I am not sure which it chooses, so you may want to place only one in the models folder. |
|
|
|
The `olderFormat` file was created with the aim of then converting it to GGML for use with [llama.cpp](https://github.com/ggerganov/llama.cpp). At present this file does not work. |
|
|
|
## How to run with `text-generation-webui` |
|
|
|
GPTQ model files provided will not load as-is with [oobaboogas text-generation-webui](https://github.com/oobabooga/text-generation-webui). |
|
|
|
These model files require the latest version of the GPTQ code. |
|
|
|
Here are the commands I used to clone the Triton branch of GPTQ-for-LLaMa, clone text-generation-webui, and install GPTQ into the UI: |
|
``` |
|
git clone https://github.com/qwopqwop200/GPTQ-for-LLaMa |
|
git clone https://github.com/oobabooga/text-generation-webui |
|
mkdir -p text-generation-webui/repositories |
|
ln -s GPTQ-for-LLaMa text-generation-webui/repositories/GPTQ-for-LLaMa |
|
``` |
|
|
|
Then install this model into `text-generation-webui/models` and launch the UI as follows: |
|
``` |
|
cd text-generation-webui |
|
python server.py --model koala-7B-4bit-128g --wbits 4 --groupsize 128 --model_type Llama # add any other command line args you want |
|
``` |
|
|
|
The above commands assume you have installed all dependencies for GPTQ-for-LLaMa and text-generation-webui. Please see their respective repositories for further information. |
|
|
|
If you cannot use the Triton branch of GPTQ for any reason, you can alternatively use the CUDA branch instead: |
|
``` |
|
git clone https://github.com/qwopqwop200/GPTQ-for-LLaMa -b cuda |
|
cd GPTQ-for-LLaMa |
|
python setup_cuda.py install |
|
``` |
|
Then link that into `text-generation-webui/repositories` as described above. |
|
|
|
## How the Koala delta weights were merged |
|
|
|
The Koala delta weights were originally merged using the following commands, producing [koala-7B-HF](https://huggingface.co/TheBloke/koala-7B-HF): |
|
``` |
|
git clone https://github.com/young-geng/EasyLM |
|
|
|
git clone https://huggingface.co/nyanko7/LLaMA-7B |
|
|
|
mkdir koala_diffs && cd koala_diffs && wget https://huggingface.co/young-geng/koala/resolve/main/koala_7b_diff_v2 |
|
|
|
cd EasyLM |
|
|
|
PYTHON_PATH="${PWD}:$PYTHONPATH" python \ |
|
-m EasyLM.models.llama.convert_torch_to_easylm \ |
|
--checkpoint_dir=/content/LLaMA-7B \ |
|
--output_file=/content/llama-7B-LM \ |
|
--streaming=True |
|
|
|
PYTHON_PATH="${PWD}:$PYTHONPATH" python \ |
|
-m EasyLM.scripts.diff_checkpoint --recover_diff=True \ |
|
--load_base_checkpoint='params::/content/llama-7B-LM' \ |
|
--load_target_checkpoint='params::/content/koala_diffs/koala_7b_diff_v2' \ |
|
--output_file=/content/koala_7b.diff.weights \ |
|
--streaming=True |
|
|
|
PYTHON_PATH="${PWD}:$PYTHONPATH" python \ |
|
-m EasyLM.models.llama.convert_easylm_to_hf --model_size=7b \ |
|
--output_dir=/content/koala-7B-HF \ |
|
--load_checkpoint='params::/content/koala_7b.diff.weights' \ |
|
--tokenizer_path=/content/LLaMA-7B/tokenizer.model |
|
