Python getting IDE linter to see from System imports within pythonnet's clr

I am using the pythonnet package in MSMQ communications. In my IDE (PyCharm CE), I have the following sample code:

#!/usr/bin/env python3


import pythoncom

import clr



clr.AddReference("System")

clr.AddReference("System.Messaging")

from System import TimeSpan

from System.Messaging import MessageQueue


Aside: this code works fine when I actually run it using Python 3.6.

And below is a screenshot of what it looks like inside PyCharm.

What I Am Seeing

  • For System it says: Unresolved reference 'System'

Other than using noqa comments, how can I get my PyCharm linting to do the following:

  • Not complain about from System import XYZ?

Versioning Info

  • IDE: PyCharm Community Edition 2019.2
  • pythonnet 2.3.0, installed in a virtual environment
pycharm python.net clr ide python

This is my complete answer, according to our exchanges.

Issue #1

No module named clr

After some checks, it seems there was a kind of mix between the operating system environment, and your project's virtual environment.

Solution: delete and re-create properly virtual environment fixed it

Issue #2

Unresolved reference 'System'

In this case where corresponding modules are loaded dynamically, your best solution is to disable PyCharm's Inspector on these specific lines; thus you won't loose anything else in your IDE.

You can see How to disable inspection.

In my sandbox, I just had to:

  • go on corresponding source code lines with warning (one after the other)
  • use the More actions context menu on the error (System in this case)
  • use the Ignore unresolved reference 'pythonnet_tests.System' sub-menu
  • use finally the Suppress for statement

Each time the corresponding source code line, will be preceded by a comment line:

# noinspection PyUnresolvedReferences

And that's it!
