Description Andreas Billmeier 2019-11-10 10:39:35 UTC
Hi,

using profile 17.1, media-libs/opencv-3.4.1-r6 sets an unappropriated python library suffix, so 'cv2.cpython-37m-x86_64-linux-gnu.so' is installed in /usr/lib64/python3.x/site-packages instead of '/usr/lib/python3.7/site-packages' and will not be found by Python.

As a short hack, if i just remove

481c481
< 		# -DLIBPY_SUFFIX=64
---
> 		-DLIBPY_SUFFIX=64

it works again with profile 17.1.

Here's my environment:

Try linking the two paths together. I use a Mac environment and was facing similar issues with packages being installed in the 2.7.6 and not the 3.8.1. I first used pyenv but it was rather inconvenient for me to set up each individual environment while working. Moreover, pyenv disrupted my pip path and the python paths, rendering the two non interactive. So I removed pyenv and simply linked it to the 3.8.1, thus creating a stable path for the pip to follow.
I did not use portage, so I am not aware of the exact command at the moment, but I will surely try and get back to you with it.
