I get the following error in my Python script following the psspy.psseinit(2000) command. Has anyone seen this before and do they know what the fix is?

Update:

I have managed to resolve this issue by uninstalling various extraneous installations of Python on the machine e.g Anaconda installs etc. It seems there must have been some kind of path issue or similar which was pointing PSS/E to the wrong Python files or executables.

The Python installed is the 32 bit version. The manual says 34.7.0 is compatible with Python 3.7 and comes bundled with 3.7.3 so it should work. However, I note the version I downloaded is a release candidate 34.7.0 RC3, so perhaps there is a bug?

During PSSe installation, select the option to install python 3.7 You do not have to download it.

PSSe 34 installs python 3.7, 32-bit at c:\python37

Your python path "C:\Users\bradh\AppData\Local\Programs\Python\Python373\lib\site.py" seems to be from a process other that PSSe and such python could be 64-bit. PSSe v.34 only work with python in 32-bit format. Consider uninstalling those extra python version and re-install PSSe 34 with default python v.3.7

The last time I checked, PSSE V34 is compatible with Python 3.4.

PSSE v34.8.0 works with Python v.3.4 or v.3.7, also v.2.7 but the installation process only install python 3.7

OP is running V34.7.0, perhaps that's not compatible.
