I'm creating new venv (using virtualenv) with Python 3.12.
The only two packages I'm installing are libsumo and pyarrow.
When I run only this line:
import libsumo
or only this line:
import pyarrow
Everything is working fine. However once I try to import both, the second one fails.
import libsumo
import pyarrow
import pyarrow.lib as _lib ImportError: DLL load failed while importing lib: Die angegebene Prozedur wurde nicht gefunden.
Package versions:
System:
Just to have an answer here: It is important that libsumo is linked against the same Arrow version as pyarrow. Currently this is 20.0.0 but I agree that it would be nice if libsumo tells you that that's why I opened a ticket: https://github.com/eclipse-sumo/sumo/issues/17324
So the solution for the immediate issue is to downgrade pyarrow by doing pip install pyarrow==20.0.0.
