I'm trying to run https://github.com/luxonis/depthai-experiments/tree/master/gen2-depth-people-counting but i get the following error looks like a problem with the replay

Traceback (most recent call last):

I'm running it with python main.pyin a virtual env with all the packages from requirements.txt installed

Hi RafaelRodriguez
Hi, seems like the path class cannot be converted to string by cv2. Ill dig around some more, in the meantime, if you change the replay. py script line 52 to:
self.readers[name] = VideoCapReader(str(filePath)) it should work.

Thanks,
Jaka
