@lolawang22 hi there,

Thank you for reporting this issue. The ScannerError you're encountering typically indicates a problem with parsing a YAML file, which is often due to formatting issues.

To help us diagnose and resolve this issue more effectively, could you please provide a minimal reproducible example? This will allow us to replicate the problem on our end. You can find guidelines on how to create a minimal reproducible example here.

Additionally, please ensure that you are using the latest versions of all relevant packages, including ultralytics, PyYAML, and any other dependencies. Sometimes, updating to the latest version can resolve such issues.

Here's a quick checklist to help you troubleshoot:

1. Check YAML Files: Ensure that all YAML files you are using are correctly formatted. YAML is sensitive to indentation and special characters.
2. Update Packages: Run pip install --upgrade ultralytics pyyaml to make sure you have the latest versions.
3. Recreate Virtual Environment: Sometimes, issues can arise from the virtual environment itself. Consider recreating your virtual environment and reinstalling the packages.

If the issue persists after these steps, please share the specific YAML file or the relevant portion of it that might be causing the error. This will help us pinpoint the problem more accurately.

Thank you for your cooperation, and we look forward to resolving this issue for you! 😊
