If you only specify opencv in your environment, you'll get an error when you try to run import cv2:

--------------------------------------------------------------------------- ImportError Traceback (most recent call last) Cell In[3], line 1 ----> 1 import cv2 ImportError: libOpenGL.so.0: cannot open shared object file: No such file or directory
Instead of installing opencv in your environment, you can install libopencv headless, like this:
channels: - conda-forge dependencies: - python=3.10 - libopencv *=headless*
We should document this process, probably as an FAQ, since we have a lot of users who are interested in opencv.
