Ludwig documentation

Website: ludwig.ai

Ludwig's documentation is built using MkDocs and the beautiful Material for MkDocs theme, deployed using Mike.

Edit-refresh development

  1. Install requirements.

    pip install -r requirements.txt

  2. If the content of contributing guide in the Ludwig code repository has changed, then run

    python code_doc_autogen.py

    in order to download it into docs/developer_guide/contributing.md in this repository (since all documentation content is served from local files). Be sure to commit the new version of the contributor guide into the repository.

    If the contributor guide source did not change, then skip this step.

  3. In terminal, keep a window running:

    mkdocs serve

  4. Navigate to http://localhost:8000 to view your changes.

💡 No need to return to your terminal -- changes will be automatically reflected as you save changes to files.

Versioned docs

The full ludwig.ai website is deployed using mike, a wrapper around mkdocs, which deploys includes previous snapshots of documentation for older versions of Ludwig.

To see how the fully rendered ludwig.ai website with multiple versions looks:

  1. Export the ludwig version to an environment variable:

    export LUDWIG_VERSION=$(python -c "import ludwig; print('.'.join(ludwig.__version__.split('.')[:2]))")

  2. Run mike deploy

    mike deploy --update-aliases $LUDWIG_VERSION latest --ignore

  3. In a separate tab, run the mike web server:

    mike serve --ignore

  4. Navigate to http://localhost:8000 to view.

⚠️ mike serve is not edit-refreshable. In order to see changes reflected, re-run mike deploy and mike serve.

mike deploy --update-aliases $LUDWIG_VERSION latest --ignore
mike serve --ignore

Updating docs for older Ludwig versions

The CI system will by default publish new docs for the latest version every day.

Updating docs for an older version of Ludwig needs to be done manually.

Create a new branch:

git checkout -b $VERSION

Install the relevant version of Ludwig and generate documentation:

pip install ludwig==$VERSION
python code_doc_autogen.py

Use the --push option to publish the changes to the remote repo. Be sure to only include the major and minor version (e.g., 0.5 instead of 0.5.1):

mike deploy --push $MAJOR_MINOR_VERSION

Regenerating API documentation

Markdown files under docs/user_guide/api/ are generated automatically. To regenerate these files, run:

python code_doc_autogen.py
