Technical Architecture and Implementation

The architecture of LLaMA-Factory is designed to facilitate easy integration and management of datasets. The core component is the dataset_info.json file, which contains all necessary configurations for dataset usage. Below is a sample structure of this file:

{
  "数据集名称": {
    "hf_hub_url": "Hugging Face 的数据集仓库地址",
    "file_name": "data.json",
    "formatting": "alpaca",
    "columns": {
      "prompt": "instruction",
      "query": "input",
      "response": "output"
    }
  }
}

This structure allows users to define various parameters such as dataset names, file names, and column mappings, ensuring flexibility in dataset management.
