import dpsimpy fails in Docker/Binder

[georgii-tishenin]

Describe the bug
When using the Python wrapper of DPsim via Binder (e.g. Quickstart Guide.ipynb example), the import of dpsimpy fails.

To Reproduce
Steps to reproduce the behavior:

1. Go to DPsim GitHub
2. Click on launch Binder badge in README file.
3. Open QuickStart Guide.ipynb
4. Run import dpsimpy cell -> produces an error: ImportError: /home/jovyan/.local/lib/python3.13/site-packages/dpsimpy.cpython-313-x86_64-linux-gnu.so: undefined symbol: villas__node__message__unpack

Expected behavior
no error in step 4.

Additional context
This seems to happen only in the Docker environment using the Dockerfile. Hence:

• Local (not Docker-based) installation of dpsimpy works without issues.
• CI passes. This may be worth to add a test to catch this problem in the future.

I have just given the the QuickStart notebook another try and it seems to work fine :)

Hi @stv0g. Yes, you're right, there was a quick fix in #433 and a proper fix in #445 . Before closing this issue we'd like to also add an automatic check in the CI to catch this in the future (see sub-issue #435). Or would you suggest separating/not waiting for #435 and closing this issue already?

Thanks @georgii-tishenin for the explanation. I think its reasonable to keep this ticket open until the sub-ticket has been resolved.
