ValueError while trying to load a *.stp file within a worker thread

[MarcelHeu]

Hello,

I try to load a *.stp file within a worker thread with the following line of code:

mesh = trimesh.Trimesh(**trimesh.interfaces.gmsh.load_gmsh("model.stp"))

Unfortunately i got the following error message:

Traceback (most recent call last):

  File "C:\Users\ThomasFuhrer\Desktop\01 Testprogram\WorkerThreads.py", line 331, in run
    mesh = trimesh.Trimesh(**trimesh.interfaces.gmsh.load_gmsh("model.stp"))

  File "C:\Developer\WPy64-3950\python-3.9.5.amd64\lib\site-packages\trimesh\interfaces\gmsh.py", line 37, in load_gmsh
    import gmsh

  File "C:\Developer\WPy64-3950\python-3.9.5.amd64\lib\site-packages\gmsh.py", line 41, in <module>
    oldsig = signal.signal(signal.SIGINT, signal.SIG_DFL)

  File "C:\Developer\WPy64-3950\python-3.9.5.amd64\lib\signal.py", line 47, in signal
    handler = _signal.signal(_enum_to_int(signalnum), _enum_to_int(handler))

ValueError: signal only works in main thread of the main interpreter

Do you know how to solve it? Is it possible to somehow load a *.stp file while running the function within a worker thread?

Best regards, Marcel
