# OpenAssistant LLaMA 30B RLHF 2

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-rlhf-2-llama-30b-7k-steps` model. The same process can be applied to other models in future, but the checksums will be different..

**This process is tested only on Linux (specifically Ubuntu). Some users have reported that the process does not work on Windows. We recommend using WSL if you only have a Windows machine.**

**Some users have also had problems with line endings causing JSON XORs not to work. Please ensure your JSON files have LF (not CR/LF) line endings.**

To use OpenAssistant LLaMA-Based Models, you should have a copy of the original LLaMA model weights and add them to a `llama` subdirectory here. If you cannot obtain the original LLaMA, see the note in italic below for a possible alternative.

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
```

*If you do not have a copy of the original LLaMA weights and cannot obtain one, you may still be able to complete this process. Some users have reported that [this model](https://huggingface.co/elinas/llama-30b-hf-transformers-4.29) can be used as a base for the XOR conversion. This will also allow you to skip to Step 7. However, we only support conversion starting from LLaMA original checkpoint and cannot provide support if you experience issues with this alternative approach.*

**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.**

1. Create a clean Python **3.10** virtual environment & activate it:

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

2. Clone transformers repo and switch to tested version:

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

3. Install **exactly** these dependency versions:

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

4. 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
regex==2023.3.23
requests==2.28.2
sentencepiece==0.1.98
tokenizers==0.13.3
torch==1.13.1
tqdm==4.65.0
transformers @ file:///mnt/data/koepf/transformers
typing_extensions==4.5.0
urllib3==1.26.15
```

5. 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
```

6. 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

eeec4125e9c7560836b4873b6f8e3025  ./tokenizer.model
99762d59efa6b96599e863893cf2da02  ./pytorch_model-00006-of-00007.bin

6b2e0a735969660e720c27061ef3f3d3  ./special_tokens_map.json
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.**

7. Once you have LLaMA weights in the correct format, you can apply the XOR decoding:

```
python xor_codec.py oasst-rlhf-2-llama-30b-7k-steps/ oasst-rlhf-2-llama-30b-7k-steps-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**.

8. Now run `find . -type f -exec md5sum "{}" +` in the output directory (here `oasst-rlhf-2-llama-30b-7k-steps`). You should get a file with exactly these checksums:

```
d08594778f00abe70b93899628e41246  ./pytorch_model-00007-of-00007.bin
f11acc069334434d68c45a80ee899fe5  ./pytorch_model-00003-of-00007.bin
9f41bd4d5720d28567b3e7820b4a8023  ./pytorch_model-00001-of-00007.bin
27b0dc092f99aa2efaf467b2d8026c3f  ./added_tokens.json

9a4d2468ecf85bf07420b200faefb4af  ./config.json
deb33dd4ffc3d2baddcce275a00b7c1b  ./tokenizer.json
13a3641423840eb89f9a86507a90b2bf  ./pytorch_model.bin.index.json
ed59bfee4e87b9193fea5897d610ab24  ./tokenizer_config.json
704373f0c0d62be75e5f7d41d39a7e57  ./special_tokens_map.json
ed991042b2a449123824f689bb94b29e  ./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.**
