# Health Checks cuML provides a small set of health checks (smoke tests) to verify that cuML is working correctly after installation or as part of automated processes such as CI. These checks are also used by the RAPIDS CLI’s `rapids doctor` command when the CLI is installed. ## Run standalone You can run all cuML health checks from the command line: ```console python -m cuml.health_checks ``` Use `--verbose` or `-v` for extra output when a check passes. The command exits with 0 if all checks pass, or 1 if any check fails. ## Run via RAPIDS CLI When [rapids-cli](https://github.com/rapidsai/rapids-cli) is installed, the same cuML checks are registered as plugins and run as part of: ```console rapids doctor ``` See the [rapids-cli documentation](https://github.com/rapidsai/rapids-cli#check-plugins) for how checks are discovered and how to run with `--verbose` or filter by name.
