OpenCV problem

[jogl]

I am trying to create my own Haar Cascade classifier.

I keep getting the "Invalid background description file." error.

I have tried this on two different computers, one running Debian 9 and the other Ubuntu 18.04.

I have tried all the solutions that I could find on the web.

I was roughly following the tutorial here: https://pythonprogramming.net/haar-casca...-tutorial/

Anybody have any experience with this? Suggestions?

Thanks

P.S.: Don't know haw I ended up with this in the Bar!

@jogl - I moved the thread to Bar because it is not a general Python coding question. You are using a very specific library/program, which we don't even see.

If you share your original code from which it would be possible to trace the source of error, thread can go back to programming subforum.
