AfterScan does not start after installation + No module named 'cv2'

[o2m]

Hello everyone,

I installed AfterScan on a HP Elite x2 Windows notebook.
I followed the instructions and installed the open source projects Python, OpenCV, NumPy, FFmpeg, and Pillow.

When I start AfterScan, I get the following message (see also attached screenshot):
Traceback (most recent call last):
File “C:\Program Files\afterscan\AfterScan.py”, line 54, in ‘module’ import cv2
ModuleNotFoundError: No module named 'cv2'

Since I would like to use AfterScan for post-processing my grandfather's 8mm films, it would be great if I could get some help here. Thank you in advance!

I use Linux, no idea how python modules are installed in Windows (via pip I guess). Providing the details on how you have installed the modules could help to troubleshoot. If you don't get any answers here, you could try the discord group, it is usually more reactive (and when you get an answer, paste it here, it might help others).

Thanks for your reply, jareff-g.
I installed everything according to the instructions. The interim tests of the individual tools all worked.
Can you please send me the link to the Discord server?
