I have updated TVM to master branch several days ago and this problem started after that. Importing TVM before OpenCV works without any problem, while vice versa gives the error below. It’s not a big deal, since there is a workaround but I just wanted to know the reason. Thanks.
>>> import cv2
>>> import tvm

OSError: libnvrtc.so.10.0: cannot open shared object file: No such file or directory
This works:
>>> import tvm
>>> import cv2
>>>
Edit: I have CUDA 10.2. I don’t know why TVM tries to link libnvrtc.so.10.0. OpenCV version: 4.3.0-dev
