OpenAssistant LLaMa-Based Models

Due to the license attached to LLaMa models by Meta AI it is not possible to directly distribute LLaMa-based models. Instead we provide XOR weights for the OA models.

Thanks to Mick for writing the xor_codec.py script which enables this process

The Process

Note: This process applies to oasst-sft-6-llama-30b model. The same process can be applied to other models in future, but the checksums will be different..

To use OpenAssistant LLaMa-Based Models, you need to have a copy of the original LLaMa model weights and add them to a llama subdirectory here.

Ensure your LLaMa 30B checkpoint matches the correct md5sums:

f856e9d99c30855d6ead4d00cc3a5573  consolidated.00.pth
d9dbfbea61309dc1e087f5081e98331a  consolidated.01.pth
2b2bed47912ceb828c0a37aac4b99073  consolidated.02.pth
ea0405cdb5bc638fee12de614f729ebc  consolidated.03.pth
4babdbd05b8923226a9e9622492054b6  params.json

Important: Follow these exact steps to convert your original LLaMa checkpoint to a HuggingFace Transformers-compatible format. If you use the wrong versions of any dependency, you risk ending up with weights which are not compatible with the XOR files.

Create a clean Python 3.10 virtual environment & activate it:

python3.10 -m venv xor_venv
source xor_venv/bin/activate

Clone transformers repo and switch to tested version:

git clone https://github.com/huggingface/transformers.git
cd transformers
git checkout d04ec99bec8a0b432fc03ed60cea9a1a20ebaf3c
pip install .

Install exactly these dependency versions:

pip install torch==1.13.1 accelerate==0.18.0 sentencepiece==0.1.98 protobuf==3.20.1

Check pip freeze output:

accelerate==0.18.0
certifi==2022.12.7
charset-normalizer==3.1.0
filelock==3.12.0
huggingface-hub==0.13.4
idna==3.4
numpy==1.24.2
nvidia-cublas-cu11==11.10.3.66
nvidia-cuda-nvrtc-cu11==11.7.99
nvidia-cuda-runtime-cu11==11.7.99
nvidia-cudnn-cu11==8.5.0.96
packaging==23.1
protobuf==3.20.1
psutil==5.9.5
PyYAML==6.0

While in transformers repo root, run HF LLaMA conversion script:

python src/transformers/models/llama/convert_llama_weights_to_hf.py --input_dir <input_path_llama_base>  --output_dir <output_path_llama30b_hf> --model_size 30B

Run find . -type f -exec md5sum "{}" + in the conversion target directory (output_dir). This should produce exactly the following checksums if your files are correct:

462a2d07f65776f27c0facfa2affb9f9  ./pytorch_model-00007-of-00007.bin
e1dc8c48a65279fb1fbccff14562e6a3  ./pytorch_model-00003-of-00007.bin

5cfcb78b908ffa02e681cce69dbe4303  ./pytorch_model-00002-of-00007.bin

Important: You should now have the correct LLaMa weights and be ready to apply the XORs. If the checksums above do not match yours, there is a problem.

Once you have LLaMa weights in the correct format, you can apply the XOR decoding:

python xor_codec.py oasst-sft-6-llama-30b/ oasst-sft-6-llama-30b-xor/ llama30b_hf/

You should expect to see one warning message during execution:

Exception when processing 'added_tokens.json'

This is normal. If similar messages appear for other files, something has gone wrong.

Now run find . -type f -exec md5sum "{}" + in the output directory (here oasst-sft-6-llama-30b). You should get a file with exactly these checksums:

970e99665d66ba3fad6fdf9b4910acc5  ./pytorch_model-00007-of-00007.bin
659fcb7598dcd22e7d008189ecb2bb42  ./pytorch_model-00003-of-00007.bin

ae48c4c68e4e171d502dd0896aa19a84  ./pytorch_model-00002-of-00007.bin

If so you have successfully decoded the weights and should be able to use the model with HuggingFace Transformers. If your checksums do not match those above, there is a problem.
