I recently upgraded to PyCharm Professional 2020.3.2 on Mac OS Catalina 10.15.7. When I did that it disabled code inspection for the project I had open at the time I upgraded. It is odd that it is only one project that code inspection seems to be disabled on. I checked the preferences and almost all the settings under Preferences->Editor->Inspections for python are checked. If I open another project the code inspection works.
One simple example of a code inspection that is not working is adding an import for a package that is not used. Previously I would see PEP8 warnings as well is the line highlighted in some manner to indicate the import is unused.
Here is what I've tried to date that hasn't worked:
- Exit out of pycharm completely and restart
- Downgrade back to previous version (2020.3)
- Recreated the project code inspection is not working in
- Restore the settings to the default settings (File->Manage IDE Settings->Restore Default Settings)
