PyScipOpt references old Scip version. Problem at import of pyscipopt

[windgaetter]

Describe the bug
Since the last Scip update, PyScipOpt references the wrong libscip version. This results in an error when importing pyscipopt. Currently conda automatically installs Scip 9.2 and PyScipOpt 5.2.1

To Reproduce
Create conda environment and install pyscipopt from conda-forge. Try loading pyscipopt

Expected behavior
I would have expected, that the version is automatically updated or the referencing scip version fixed.

Screenshots

import pyscipopt
Traceback (most recent call last):
File "", line 1, in
File "/home/wind_lu/.conda/envs/test_env/lib/python3.12/site-packages/pyscipopt/init.py", line 11, in
from pyscipopt.scip import Model
ImportError: libscip.so.9.1: cannot open shared object file: No such file or directory

System

• OS: Ubuntu
• 22.04
• Scip 9.2
• conda-forge

Hey @windgaetter, thanks for letting us know. In the meantime, can you try pip install pyscipopt and see if this works?

[windgaetter]

That works for me. No error when I try to import it.

We use PyScipOpt in one of our conda packages. So,when you have that fix ready, we will be happy to use it again !
