Practical overview
When it fits
Use Opendialog when you need a self-managed toolkit for Chinese open-domain dialogue and can provide the Linux, Python, GPU, data and supporting-service environment its workflows require.
Who it is for
- Developers building Chinese open-domain conversational systems.
- Researchers or practitioners training and evaluating generative or retrieval dialogue models.
- Teams preparing a Flask-based service around a trained dialogue model.
Documented uses
- Train GPT-2-based generative dialogue models or BERT-based retrieval models on prepared datasets.
- Prepare and load dialogue datasets and evaluate generated test results with the included utilities.
- Use Elasticsearch for coarse retrieval in retrieval-based dialogue workflows.
- Serve a dialogue model through the included Flask interface.
Requirements & limits
The repository is public and identifies the project as MIT-licensed.
- The documented target environment is Linux/Ubuntu 16.04+, Python 3.6+ and a GPU.
- Retrieval-based dialogue requires Elasticsearch and the IK Chinese tokenizer.
- MongoDB is used to store conversation history and related data.
- Dataset preparation and placement in the expected
datapaths are part of the workflow.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Prepare the documented Linux environment
Set up the prerequisites described for training and serving Opendialog models.
Before you start
- Linux/Ubuntu 16.04 or later
- Python 3.6 or later and a GPU
- The repository and its requirements file
Steps
Install the Python dependencies with the command below.
pip install -r requirements.txtFor retrieval-based dialogue, install Elasticsearch and its IK Chinese tokenizer.
Install MongoDB and start the service for conversation-history and related data storage.
Expected outcome
The documented system, Python and supporting-service prerequisites are prepared.
Guide limitations
- This covers environment preparation only; it does not confirm that a model runs successfully.
- Training and serving also require the appropriate data and model workflow.
Prepare datasets for model training
Place dataset and vector files in the locations the README describes before training.
Before you start
- The OpenDialog repository
- A dataset and its preparation details
- The
datadirectory
Steps
Review
data/README.mdfor dataset details and preprocessing.Place dataset files in the corresponding subdirectory under
data.Place
chinese_w2v.txtandenglish_w2v.binin thedatadirectory when using those vector files.
Expected outcome
The expected dataset and vector-file locations are populated for the later training stage.
Guide limitations
- The README points to a Baidu Cloud dataset link; this guide does not establish access to that download.
- Training itself is a separate stage and requires the prepared environment and selected model.
