## Changelog
|
|
|
|
[23/06/22] Now we align the [demo API](src/api_demo.py) with the [OpenAI's](https://platform.openai.com/docs/api-reference/chat) format where you can insert the fine-tuned model in arbitrary ChatGPT-based applications.
|
|
|
|
[23/06/15] Now we support training the baichuan-7B model in this repo. Try `--model_name_or_path baichuan-inc/baichuan-7B` and `--lora_target W_pack` arguments to use the baichuan-7B model. If you want to train with RTX3090, use `git checkout baichuan-7b-rtx3090` to switch to the `baichuan-7b-rtx3090` branch and try the `--baichuan_rtx_gpu true` argument. (Other RTX series GPUs can also be tried)
|
|
|
|
[23/06/03] Now we support quantized training and inference (aka [QLoRA](https://github.com/artidoro/qlora)). Try `--quantization_bit 4/8` argument to work with quantized model. (experimental feature)
|
|
|
|
[23/05/31] Now we support training the BLOOM & BLOOMZ models in this repo. Try `--model_name_or_path bigscience/bloomz-7b1-mt` and `--lora_target query_key_value` arguments to use the BLOOMZ model.

## Getting Started
|
|
|
|
### Data Preparation (optional)
|
|
|
|
Please refer to `data/example_dataset` for checking the details about the format of dataset files. You can either use a single `.json` file or a [dataset loading script](https://huggingface.co/docs/datasets/dataset_script) with multiple files to create a custom dataset.
|
|
|
|
Note: please update `data/dataset_info.json` to use your custom dataset. About the format of this file, please refer to `data/README.md`.
|
|
|
|
### Dependence Installation (optional)
|
|
|
|
```bash
|
|
git clone https://github.com/hiyouga/LLaMA-Efficient-Tuning.git

|
|
--max_samples 50 \
|
|
--predict_with_generate
|
|
```
|
|
|
|
We recommend using `--per_device_eval_batch_size=1` and `--max_target_length 128` at 4/8-bit evaluation.
|
|
|
|
### API / CLI / Web Demo
|
|

|
```
|
|
|
|
### Export model

|
|
--output_dir path_to_export
|
|
```
