# Open-Chinese-LLaMA |
|
|
|
This project is a **Chinese large language model base** generated through **incremental pre-training on Chinese datasets** based on [LLaMA](https://github.com/facebookresearch/llama)-7B. |
|
|
|
## Features |
|
|
|
* This project provides a Chinese pre-trained model obtained through full-tuning, including Huggingface version weights. |
|
* Compared to the original LLaMA, this model has significantly improved Chinese understanding and generation capabilities, achieving outstanding results in various downstream tasks. See [Evaluation](##Evaluation) for details. |
|
* This project provides tools for converting Huggingface version weights and Meta version weights. |
|
* Supports [🤗transformers](https://github.com/huggingface/transformers), and provides command-line tools for easy model testing. |

### Usage Notes |
|
|
|
|
|
|
|
Meta officially released [LLaMA](https://github.com/facebookresearch/llama) does not open-source weights. To comply with relevant licenses, the model released this time is of the **patch** type, and must be used in conjunction with the official original weights. |
|
|
|
We provide a [script](https://github.com/OpenLMLab/OpenChineseLLaMA) for installing the **patch**. After obtaining the official weights through regular channels, you can install the patch as follows: |
|
|
|
```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> |
|
``` |
|
|
|
Note: The installation method of this patch is inplace installation, that is, the installed patch is the complete Huggingface version of this model weight, and you can use transformers to load the model. |
|
|
|
Note: This script depends on [OpenLMLab/collie](https://github.com/OpenLMLab/collie), please install this framework using the following command: |
|
|
|
```bash |
|
pip install git+https://github.com/OpenLMLab/collie.git |
|
``` |
|
|
|
## Local Demo |
|
|
|
For quick and easy model testing, we provide a command-line version of the demo. After successfully installing the patch according to [Usage Notes](###Usage%20Notes), you can use the script to start an interactive interface: |
|
|
|
```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 |
|
``` |

## Model Format Conversion |
|
|
|
The model generated by [`patch_model.py`]((https://github.com/OpenLMLab/OpenChineseLLaMA)) in this project is **hf** format which can be loaded by [🤗transformers](https://github.com/huggingface/transformers). For convenience, we also provide a [conversion tool]((https://github.com/OpenLMLab/OpenChineseLLaMA)) between the official version model (raw) and hf: |
|
|
|
```bash |
|
python convert_model.py --model_path <path_or_name_to_your_hf_or_raw_model> |
|
--source_format hf |
|
--target_format raw |
|
--target_path <path_you_want_to_save_the_converted_model> |
|
--raw_parallel_degree 2 |
|
--raw_parallel_devices 0,1 |
|
``` |
|
|
|
Tip: When converting a model in raw format, you need to specify the tensor parallel size and corresponding device, and it can only be converted on a machine with a corresponding number of graphics cards. |
