Got exit code 1073741819 (0xC0000005) from python demo

[xinxin8816]

Hi there, I try to exec demo with Python 3.9 on Windows, sometimes got unexpected exit, with code -1073741819 (0xC0000005) , that err from C shared lib I think, and that because of index out of range usually. I'm not good at Golang and not founded the true reason from code, give me some advice to fix it please, thx.

Can you show me exactly what kind of errors are you getting? Just FYI these demos have been tested on Python2 and OpenCV2 so it might be related to the Python version also on which you are trying to run it.

Nothing exactly others, just response err code and exit. That err code correlate with out of range in my experience. Python2 may working well, but Python2 has out of date now.

I'm aware about that, only that because I have ported the library to WASM I didn't updated the Python examples to run on Python3. But I have tried it with Python3 and OpenCV4 and sometimes just exited without printing any errors. That's why I asked if you could have shown the errors you got.

Only got this unuseful message, means: Process has been exited, exit code is -1073741819 (0xC0000005)

I have tried on a MacOS with Python 3.9.1 installed and the demos are running, but strangely on Windows in most of the cases the application exits without showing any errors. I was trying to debug it and most probably is related to the data type transfer from Go to Python using ctypes.

I ran in pycharm with debug mode, and than got exit code. If running in cmd or powershell, that output nothing.

I'm closing this ticket, the issue is fixed now.
