Pyinstaller Error after exe built: ModuleNotFoundError: No module named 'cmath'

Question

I'm having a hard time converting my python code to an exe. After I use pyinstaller to convert my code to an exe, it gives me an error that its missing an import when I run it. Here's the full log:

Traceback (most recent call last):

The name of the file I'm trying to convert is new.py which relies on pandas which apparently can't find a module called cmath. How do I fix this? Is there anyway for me to build an exe?

Answer 1

Add --hidden-import cmath to the pyinstaller run.
