CI Pipeline Configuration

Configure CI behavior by applying the relevant labels:

• SKIP_CI - Skip all continuous integration tests
• INCLUDE_NOTEBOOKS_TESTS - Execute notebook validation tests in pytest
• INCLUDE_SLOW_TESTS - Execute tests labelled as slow in pytest for extensive testing

Note

By default, the notebooks validation tests are skipped unless explicitly enabled.

Authorizing CI Runs

We use copy-pr-bot to manage authorization of CI
runs on NVIDIA's compute resources.

• If a pull request is opened by a trusted user and contains only trusted changes, the pull request's code will
  automatically be copied to a pull-request/ prefixed branch in the source repository (e.g. pull-request/123)
• If a pull request is opened by an untrusted user or contains untrusted changes, an NVIDIA org member must leave an
  /ok to test comment on the pull request to trigger CI. This will need to be done for each new commit.

Usage

TODO: Add code snippet

Pre-submit Checklist
