[COM] Communication issue with pyvisa-py

[mingdu2]

I have a python project with multiple scripts converted to simplified.exe by pyinstaller. the following code ran into a problem.

// simplified.py import visa rm = pyvisa.ResourceManager('@py')

error message is while running simplified.exe Wrapper not found: No package named pyvisa-py of course , running simplified.py has no issue.

Wondering if someone here may have some idea . I appreciate it. Randy

I think this is not the first time a similar issue is reported and I believe it boils down to the fact that pyinstaller does not pick up pyvisa-py as a dependency of your scrip (because you do not import it explicitely). I am not familiar with Pyinstaller but if you can force it to include it in the exe it should work. If you manage to figure your issue out please consider making a PR to improve the documentation.

Does this guide from pyinstaller docs help you? https://pyinstaller.readthedocs.io/en/stable/when-things-go-wrong.html#listing-hidden-imports
