Overview

Easy Dataset is an application specifically designed for creating fine-tuning datasets for Large Language Models (LLMs). It provides an intuitive interface for uploading domain-specific files, intelligently splitting content, generating questions, and producing high-quality training data for model fine-tuning.

With Easy Dataset, you can transform domain knowledge into structured datasets, compatible with all LLM APIs that follow the OpenAI format, making the fine-tuning process simple and efficient.

Features

• Intelligent Document Processing: Supports intelligent recognition and processing of multiple formats including PDF, Markdown, DOCX, etc.
• Intelligent Text Splitting: Supports multiple intelligent text splitting algorithms and customizable visual segmentation
• Intelligent Question Generation: Extracts relevant questions from each text segment
• Domain Labels: Intelligently builds global domain labels for datasets, with global understanding capabilities
• Answer Generation: Uses LLM API to generate comprehensive answers and Chain of Thought (COT)
• Flexible Editing: Edit questions, answers, and datasets at any stage of the process
• Multiple Export Formats: Export datasets in various formats (Alpaca, ShareGPT, multilingual-thinking) and file types (JSON, JSONL)
• Wide Model Support: Compatible with all LLM APIs that follow the OpenAI format
• User-Friendly Interface: Intuitive UI designed for both technical and non-technical users
• Custom System Prompts: Add custom system prompts to guide model responses

Install with NPM

1. Clone the repository:

   git clone https://github.com/ConardLi/easy-dataset.git
   cd easy-dataset

2. Install dependencies:

   npm install

3. Start the development server:

   npm run build

   npm run start

4. Open your browser and visit http://localhost:1717

Using the Official Docker Image

1. Clone the repository:

git clone https://github.com/ConardLi/easy-dataset.git
cd easy-dataset

2. Modify the docker-compose.yml file:

services:
  easy-dataset:
    image: ghcr.io/conardli/easy-dataset
    container_name: easy-dataset
    ports:
      - '1717:1717'
    volumes:
      - ./local-db:/app/local-db
      # - ./prisma:/app/prisma  If mounting is required, please manually initialize the database file first.
    restart: unless-stopped

Note: Replace {YOUR_LOCAL_DB_PATH} and {LOCAL_PRISMA_PATH} with the actual paths where you want to store the local database. It is recommended to use the local-db and prisma folders in the current code repository directory to maintain consistency with the database paths when starting via NPM.

Note: If you need to mount the database file (PRISMA), you need to run npm run db:push in advance to initialize the database file.

3. Start with docker-compose:

docker-compose up -d

4. Open a browser and visit http://localhost:1717

Building with a Local Dockerfile

If you want to build the image yourself, use the Dockerfile in the project root directory:

1. Clone the repository:

git clone https://github.com/ConardLi/easy-dataset.git
cd easy-dataset

2. Build the Docker image:

docker build -t easy-dataset .

3. Run the container:

docker run -d \
  -p 1717:1717 \
  -v {YOUR_LOCAL_DB_PATH}:/app/local-db \
  -v {LOCAL_PRISMA_PATH}:/app/prisma \
  --name easy-dataset \
  easy-dataset

Note: Replace {YOUR_LOCAL_DB_PATH} and {LOCAL_PRISMA_PATH} with the actual paths where you want to store the local database. It is recommended to use the local-db and prisma folders in the current code repository directory to maintain consistency with the database paths when starting via NPM.

4. Open a browser and visit http://localhost:1717
