:farmer: Sdf13 Windows `ModuleNotFoundError: No module named 'sdformat13'`

[Crola1702]

Environment

• OS Version: Windows
• Source Garden build

Description

• Expected behavior: Test should pass
• Actual behavior: 44 tests fail

Steps to reproduce

1. Run a build in https://build.osrfoundation.org/job/sdformat-sdf-13-win/
2. See tests fail.

Output

Reference build: https://build.osrfoundation.org/job/sdformat-sdf-13-win/57/

Log output:

ImportError while importing test module 'C:\J\workspace\sdformat-sdf-13-win\ws\sdformat\python\test\pyAirPressure_TEST.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:

It seems the python bindings aren't working as expected for the cloud windows agent.

@azeey suggested disabling the bindings for this

I was looking into the problem. There seems to be a two different types of problems:

1. More obvious: some sdformat python test files can not find gz-math python binding. This is not a problem on sdformat (or not only) but the root cause of it is that we are not generating python bindings for gz-math on Windows https://github.com/gazebosim/gz-math/issues/532

2. The ModuleNotFoundError: No module named 'sdformat13' error seems not so obvious to me. The python module is being installed in:

   -- Installing: C:/J/workspace/sdformat-sdf-13-win/ws/install/sdformat13/lib/python/sdformat13.cp311-win_amd64.pyd

   and the test PYTHONPATH seems to point to the same place:

   233: Test command: "C:\Program Files\Python311\python.exe" "-m" "pytest" "C:/J/workspace/sdformat-sdf-13-win/ws/sdformat/python/test/pyAirPressure_TEST.py" "--junitxml" "C:/J/workspace/sdformat-sdf-13-win/ws/build/sdformat13/test_results/pyAirPressure_TEST.xml"
   233: Environment variables: 
   233:  PYTHONPATH=C:/J/workspace/sdformat-sdf-13-win/ws/install/sdformat13/lib/python/:C:/J/workspace/sdformat-sdf-13-win/ws/build/sdformat13/lib:
   233:  LD_LIBRARY_PATH=C:/J/workspace/sdformat-sdf-13-win/ws/install/sdformat13

   Might be problems with the separator character in PYTHONPATH for Windows or other kind of issues that I can not determine right now. Be careful if testing it manually due to problems with different python versions from system installation (3.11 and vcpkg 3.10).

https://github.com/gazebosim/sdformat/pull/1278 disables pybind11 tests on windows until we find a solution for this issue.

I got a similar error but on my Ubuntu jammy system, it seems that my OS can't recognise 'sdformat13' as a library file for python, i've tried to reinstall on binary and source distributions but nothing seems to work. this is the Error message i get from shell:

'Caught exception when trying to load file of format [py]: /usr/lib/python3/dist-packages/sdformat13.cpython-310-x86_64-linux-gnu.so: undefined symbol: _ZN3sdf3v139Projector10SetTextureERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE'

as I get to understand, its not creating the proper python file to make the wrapping... hope you can help!

Any solution to fix this issue I'm having similar problems with running sdf2mjcf.

@JohnkaGL and @aamodbk Is this still a problem? Have you tried updating the libsdformat13 and python3-sdformat13 packages. I tried locally on a fresh Jammy container and it seems to work fine.
