PyCharm Displays Unresolved Reference Errors for Valid Code

If PyCharm highlights your code with "unresolved reference" errors despite it being valid and successfully running, it indicates a potential issue in PyCharm's cache system. Even with a properly configured interpreter and remote paths, PyCharm may fail to recognize imported modules and functions.

This problem can occur in both local and remote interpreter scenarios. Fortunately, there is a straightforward solution to resolve it:

1. Go to the "File" menu in PyCharm.
2. Select "Invalidate Caches..."
3. Restart PyCharm

This action forces PyCharm to refresh its cache, which usually clears up the issue. The IDE will correctly recognize the imported modules and functions, resolving the "unresolved reference" errors.

If the issue persists after invalidating the caches, consider restarting PyCharm again. This should address any remaining cache-related issues and allow PyCharm to function properly.
