## How to Fine-tune DeepSeek-Coder
We provide script `finetune_deepseekcoder.py` for users to finetune our models on downstream tasks.
The script supports the training with [DeepSpeed](https://github.com/microsoft/DeepSpeed). You need install required packages by:
```bash
pip install -r requirements.txt
```
Please follow [Sample Dataset Format](https://huggingface.co/datasets/nickrosh/Evol-Instruct-Code-80k-v1) to prepare your training data.
Each line is a json-serialized string with two required fields `instruction` and `output`.
After data preparation, you can use the sample shell script to finetune `deepseek-ai/deepseek-coder-6.7b-instruct`.
Remember to specify `DATA_PATH`, `OUTPUT_PATH`.
And please choose appropriate hyper-parameters(e.g., `learning_rate`, `per_device_train_batch_size`) according to your scenario.
```bash
DATA_PATH="<your_data_path>"
OUTPUT_PATH="<your_output_path>"
MODEL_PATH="deepseek-ai/deepseek-coder-6.7b-instruct"
