hi everybody.

A strange behavior we do not understand.

on a UV/windows / 11.3.5 we have python 3.11  (the one within uv/python - no other python is installed on the machine) 

We  use module 'pandas'  in our script, release 2.2.2 is installed. 

When executed from osshell, no problem : dos /c "python path/script.py" 

When executed from uv/python, from pyCallFunction() or from TCL >PYTHON then import pandas we get this 

DLL load failed while importing aggregations: The specified module could not be found.
we do not understand what's wrong with the deploy.... What is the difference between a osshelled python call and a uv's python's one ?

any idea ? 

Many thanks for any advice 

Manu

Manu,

I recommend taking a look at the Python configuration files u2.pth (the favourite) and .pyconfig.

Manu,

The Python version you run from UniVerse is the one defined for UniVerse, the one you execute at the dos prompt is based off the PATH environment variable.

Put the UniVerse Python path in your PATH environment variable, and you should be ok.
