+ # OpenAssistant LLaMa-Based Models
6
+
7
+ 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.
8
+
9
+ Thanks to Mick for writing the `xor_codec.py` script which enables this process
10
+
11
+ ## The Process
12
+
13
+ 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..
14
+
15
+ 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.
16
+
17
+ Ensure your LLaMa 30B checkpoint matches the correct md5sums:
18
+
19
+ ```

24
+ 4babdbd05b8923226a9e9622492054b6 params.json
25
+ ```
26
+
27
+ These can be converted to HuggingFace Transformers-compatible weights using the script available [here](https://github.com/huggingface/transformers/blob/28f26c107b4a1c5c7e32ed4d9575622da0627a40/src/transformers/models/llama/convert_llama_weights_to_hf.py).
28
+
29
+ **Important**: It was tested with git version transformers 4.28.0.dev0 (git hash: **28f26c107b4a1c5c7e32ed4d9575622da0627a40**). Make sure the package tokenizers 0.13.3 is installed. Use of different versions may result in broken outputs.

+ PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python python convert_llama_weights_to_hf.py --input_dir ~/llama/ --output_dir ~/llama30b_hf/ --model_size 30B
33
+ ```
34
+
35
+ Run `find -type f -exec md5sum "{}" + > checklist.chk` in the conversion target directory. This should produce a `checklist.chk` with exactly the following content if your files are correct:

+

52
+ ```
53
+
54
+ Once you have LLaMa weights in the correct format, you can apply the XOR decoding:
55
+
56
+ ```
57
+ python xor_codec.py oasst-sft-6-llama-30b/ oasst-sft-6-llama-30b-xor/ llama30b_hf/
58
+ ```
59
+
60
+ You should expect to see one warning message during execution:
61
+
62
+ `Exception when processing 'added_tokens.json'`
63
+
64
+ This is normal. If similar messages appear for other files, something has gone wrong.
65
+
66
+ Now run `find -type f -exec md5sum "{}" + > checklist.chk` in the output directory (here `oasst-sft-6-llama-30b`). You should get a file with exactly these contents:
67
+
68
+ ```

85
+
86
+ If so you have successfully decoded the weights and should be able to use the model with HuggingFace Transformers.
