Diagnostics & TroubleshootingΒΆ
If something does not work right, the first place to look is the Known Issues section of the release notes. The next place to check is the GitHub issues page, where another user may have reported the problem.
To report a new issue, you will need a free GitHub account. Alternatively, you may report the issue via email to the project maintainers. Include code that exhibits the issue to facilitate debugging.
WebbPSF includes a helper function that will return a report with information that may be useful for troubleshooting. An example of its usage is given below:
In [1]: import webbpsf
WebbPSF log messages of level INFO and above will be shown.
WebbPSF log outputs will be directed to the screen.
In [2]: print webbpsf.system_diagnostic()
