Dear everyone,

I know PSSe33 was built as a 32-bit application. and python2.7 of 32-bit works fine with PSSe33.04 in my work.

Does anyone know can PSSe work with python 3.6 of 32-bit? I tried but failed, the problem first happened at "import psspy", and the console indicates "bad magic number in psspy..."

Maybe there are problems in my settings, or there are restrictions in PSSe version?

And I also failed to make python of 64-bit (either 3.6 or 2.7) work with PSSe.

Thanks in advance!

Gary

Hello Gary,

As far as I know, the Python modules for PSSE are compiled in v2.X of Python (note how there are numerous *.pyc files in the installation directories). Therefore, I doubt that everything will work correctly in Python v3.X.

Thank you jfconroy, yes now in my experience, only v2.X, 32 bit of Python can work with PSSe API.

Psse v.34.4 also installs python 3.4 in addition to v.2.7, while PSSe v33 only install python 2.7 therefore other python versions would give the 'magic number' error when trying to load PSSe pyc modules.

Do not open a case by double-clicking on its icon. Instead, for any v.33.x, select the PSSe link icon launcher and right-click to open its 'Properties' panel. On the 'Target' field enter ""C:\Program Files (x86)\PTI\PSSE33\PSSBIN\psse33.exe" -pyver 27", then click 'Apply'

Psse v.34.7 installs *.pyc modules for python v.3.7 and v.3.4, in addition to v.2.7, while PSSe v33 only install *.pyc modules for python 2.7 therefore other python versions (v.3.6, etc.) would give the 'magic number' error when trying to load PSSe pyc modules.

To assign a specific python version to PSSe I have separate launching link icons.

for PSSe v.34.7 + python v.3.7, select a PSSe link icon launcher (named PSSE3437) and right-click to open its 'Properties' panel. On the 'Target' field enter ""C:\Program Files (x86)\PTI\PSSE34\PSSBIN\psse34.exe" -pyver 37", then click 'Apply'

for PSSe v.34.7 + python v.2.7, select a PSSe link icon launcher (named PSSE3427) and right-click to open its 'Properties' panel. On the 'Target' field enter ""C:\Program Files (x86)\PTI\PSSE34\PSSBIN\psse34.exe" -pyver 27", then click 'Apply'
