報錯AttributeError: module ‘cv2’ has no attribute ‘ximgproc’

首先查看是否安裝opencv-contrib-python

pip list | grep opencv

顯示

opencv-contrib-python             4.4.0.46             
opencv-python                     4.8.1.78             
opencv-python-headless            4.7.0.72

說明本機上已經成功安裝 opencv-contrib-python， opencv-python ，opencv-python-headless模塊，但是為什么還會報錯module ‘cv2’ has no attribute 'ximgproc’呢？

由于版本不一致的問題導致的。

將opencv-contrib-python升級為 opencv-python 一致的版本即可解決

pip install opencv-contrib-python==4.8.1.78

解決后，再測試查看各模塊版本為：

pip list | grep opencv

顯示

opencv-contrib-python             4.8.1.78             
opencv-python                     4.8.1.78             
opencv-python-headless            4.7.0.72
