Error Thrown: Process finished with exit code -1073740791 (0xC0000409)

[Zud0taki]

Hello,

I am facing a problem with vedo, when I try to load a Mesh via the library like so:

msh = Mesh(random_pick).rotate_x(x).rotate_y(y).rotate_z(z).pos(0, 0, -380)

The only message that is given is: Process finished with exit code -1073740791 (0xC0000409) I have researched that error and it seems to connect to PyQT but my code crashes when loading the mesh so I think it has to come from somewhere else.

Sometimes it throws that error, sometimes it works. I am just at a loss right now. The random_pick variable is an .obj-file from a list of these. Here sometimes for example number 4 of the list works and sometimes it doesn´t.

I would appreciate pointers or any help you can provide.

Greetings

Uhm what is the error message?

[Zud0taki]

I am sorry I forgot to mention in the issue. The only error thrown is: Process finished with exit code -1073740791 (0xC0000409) There is no specific error which is odd.

I should have clarified earlier... have you ever heard of that message before in connection with vedo?

[marcomusy]

Not really... Are you doing it on a server by any chance? what is the output of command line

vedo

should give some info about your specs.

[Zud0taki]

The output for vedo is the following:

vedo version : 2024.5.0+dev26 (https://vedo.embl.es) vtk version : 9.3.0 numpy version : 1.24.4 python version : 3.8.18 (default, Sep 11 2023, 13:39:12) [MSC v.1916 64 bit (AMD64)] python interpreter : C:\Users\Enihcam\anaconda3\envs\SynthHumans\python.exe installation point : C:\Users\Enihcam\anaconda3\envs\SynthHumans\lib\site-packages\vedo system : Windows 10 nt AMD64

I am running the package in one of my projects in a venv (Python 3.8 on a Win10 System

If sometimes it works and sometimes it doesnt it must due to some instability of your system and/or the vtk library itself.. I don't see anything problematic in your specs .. sorry! :( Maybe you can write a minimalistic test to see if it crashes like

from vedo import Mesh
for file in files:
    m = Mesh(file)
    print(m)

[Zud0taki]

Thanks for the input! I will try to use the minimalistic test and see, if it makes any difference.

If that works I think I will try to upgrade to PyQt6. I will update you on whether either of the approaches resolves the problem. Just in case in the future someone else runs into this problem.

[Zud0taki]

Ok so I tried both options and neither of them resolved the issue. I tried an older version of my project and there it works. I will dig through the code of older versions of my project and test with them, see what I changed and maybe its obvious. I´ll keep trying and if I find a solution I`ll reopen this issue. Thank you for your time.

No problem - let me know how it goes :)
