However, please note that there are currently no matching pipelines available for this environment within the repository. Future updates will include the necessary pipelines to fully integrate SMAC with LightZero.

Key Points:

• Testing: Instructions for running tests using pytest to ensure the environment is correctly installed and functional.
• DI-engine Baselines: A link to the DI-engine SMAC baselines is included for additional reference.

Next Steps:

• Pipeline Integration: The necessary pipelines to utilize the SMAC environment within LightZero will be added in upcoming updates.
