[Colab] ImportError: cannot import name '_registerMatType' from 'cv2.cv2' (/usr/local/lib/python3.7/dist-packages/cv2/cv2.cpython-37m-x86_64-linux-gnu.so)

[Solution 해결법] Colab - ImportError: cannot import name '_registerMatType' from 'cv2.cv2' (/usr/local/lib/python3.7/dist-packages/cv2/cv2.cpython-37m-x86_64-linux-gnu.so)

 

해당 에러가 발생했을 때 취할 수 있는 2가지 경우

 

1. Recommend

!pip uninstall opencv-python-headless==4.5.5.62

!pip install opencv-python-headless==4.5.2.52

 

2.

!pip uninstall opencv-python

!pip install opencv-python

!!python -m pip install --upgrade opencv-contrib-python

 

1번 방법이 더 잘 됨. 2번 방법은 선택적으로 되기도 하고 안 되기도 함.
