Does ECOLE support WSL?

[Joky02]

I tried to install ECOLE on my WSL via conda, but it reported ImportError.

(Optimizer) joky02@DESKTOP-REE9OO5:~$ python
Python 3.11.7 | packaged by conda-forge | (main, Dec 23 2023, 14:43:09) [GCC 12.3.0] on linux

>>> import ecole

    from ecole.core import RandomGenerator, seed, spawn_random_generator, MarkovError, Default

The following is my conda info:

Hi, have you solved this problem yet? I'm having trouble using it on WSL as well.

[Joky02]

Not yet.

I had a similar problem. If you navigate to the lib folder of your specifc conda enviroment, you should have like 3 files named something like libscip.so. I just renamed one of them to libscip.so.8.0, though I don't think that's good practice, and it's a very hacky solution.
