Import error with OPENCV in Python on M1 Mac

Question

I'm trying to use OpenCV with Python but I'm continuously getting errors while importing. I'm using Anaconda virtual env and ZSH on Mac M1. I have tried installing it using conda install -c anaconda opencv and pip3 install opencv-python but I'm getting this error:

from.cv2 import * ImportError: dlopen(/Users/username/Library/Python/3.8/lib/python/site-packages/cv2/cv2.cpython-38-darwin.so, 0x0002): Library not loaded: /opt/homebrew/opt/ffmpeg/lib/libavcodec.58.dylib Referenced from: /Users/username/Library/Python/3.8/lib/python/site-packages/cv2/cv2.cpython-38-darwin.so Reason: tried: '/opt/homebrew/opt/ffmpeg/lib/libavcodec.58.dylib' (no such file), '/usr/local/lib/libavcodec.58.dylib' (no such file), '/usr/lib/libavcodec.58.dylib' (no such file)

First you should make sure that ffmpeg is installed.

for me the issue was that the ffmpeg which I had installed by brew was named like ffmpeg@4 in opt/homebrew/opt/ so it couldn't find it.

I renamed the folder to ffmpeg and the issue was fixed.
