LLaMA is a Large Language Model developed by Meta AI. It was trained on more tokens than previous models. The result is that the smallest version with 7 billion parameters has similar performance to GPT-3 with 175 billion parameters. This guide will cover usage through the official `transformers` implementation. For 4-bit mode, head over to [GPTQ models (4 bit mode) ](GPTQ-models-(4-bit-mode).md). ## Getting the weights ### Option 1: pre-converted weights * Torrent: https://github.com/oobabooga/text-generation-webui/pull/530#issuecomment-1484235789 * Direct download: https://huggingface.co/Neko-Institute-of-Science ⚠️ The tokenizers for the Torrent source above and also for many LLaMA fine-tunes available on Hugging Face may be outdated, so I recommend downloading the following universal LLaMA tokenizer: ``` python download-model.py oobabooga/llama-tokenizer ``` Once downloaded, it will be automatically applied to **every** `LlamaForCausalLM` model that you try to load. ### Option 2: convert the weights yourself 1. Install the `protobuf` library: ``` pip install protobuf==3.20.1 ``` 2. Use the script below to convert the model in `.pth` format that you, a fellow academic, downloaded using Meta's official link. If you have `transformers` installed in place: ``` python -m transformers.models.llama.convert_llama_weights_to_hf --input_dir /path/to/LLaMA --model_size 7B --output_dir /tmp/outputs/llama-7b ``` Otherwise download [convert_llama_weights_to_hf.py](https://github.com/huggingface/transformers/blob/main/src/transformers/models/llama/convert_llama_weights_to_hf.py) first and run: ``` python convert_llama_weights_to_hf.py --input_dir /path/to/LLaMA --model_size 7B --output_dir /tmp/outputs/llama-7b ``` 3. Move the `llama-7b` folder inside your `text-generation-webui/models` folder. ## Starting the web UI ```python python server.py --model llama-7b ```
