# **Llama 2 7B Chat 4-bit** |
|
|
|
Llama 2 is a collection of pretrained and fine-tuned generative text models ranging in scale from 7 billion to 70 billion parameters. This is the repository for the 7B fine-tuned model, in `npz` format suitable for use in Apple's MLX framework. |
|
|
|
Weights have been converted to `float16` from the original `bfloat16` type, because `numpy` is not compatible with `bfloat16` out of the box. |
|
|
|
How to use with [MLX](https://github.com/ml-explore/mlx). |

```bash |
|
# Install mlx, mlx-examples, huggingface-cli |
|
pip install mlx |
|
pip install huggingface_hub hf_transfer |
|
git clone https://github.com/ml-explore/mlx-examples.git |
|
|
|
# Download model |
|
export HF_HUB_ENABLE_HF_TRANSFER=1 |
|
huggingface-cli download --local-dir Llama-2-7b-chat-mlx/ mlx-community/Llama-2-7b-chat-4-bit |
|
|
|
# Run example |
|
python mlx-examples/llms/llama/llama.py --prompt "My name is " --model-path Llama-2-7b-chat-mlx/ |
|
``` |
