# Open-Chinese-LLaMA-7B-Patch

This model is a **Chinese large language model base** generated from the [LLaMA](https://github.com/facebookresearch/llama)-7B model after **secondary pre-training** on Chinese datasets.

This model is a **patch** model and must be used in conjunction with the official weights. For the installation of the patch and related tutorials, please refer to [OpenLMLab/OpenChineseLLaMA](https://github.com/OpenLMLab/OpenChineseLLaMA).

## Usage

Since the official weights for [LLaMA](https://github.com/facebookresearch/llama)-7B have not been open-sourced, the model released this time is of the **patch** type, which needs to be used in combination with the original official weights.

You can install the **patch** using `tools/patch_model.py`, for example:

```bash

python tools/patch_model.py --base_model <path_or_name_to_original_model>
                            --patch_model openlmlab/open-chinese-llama-7b-patch
                            --base_model_format <hf_or_raw>

```

The **patch** is installed in place, which means that the installed **patch** is the complete `hf` format weight. You can use `transformers` to load the model.

## Quick Experience via Command Line

The **patched** model can be easily loaded by `transformers`. For a quick experience, we provide a console Demo:

```bash

python cli_demo.py --model openlmlab/open-chinese-llama-7b-patch
                   --devices 0
                   --max_length 1024
                   --do_sample true
                   --top_k 40
                   --top_p 0.8
                   --temperature 0.7
                   --penalty 1.02

```
