Introduction:
OpenCV is a powerful computer vision library in Python that provides various functions for image and video processing. One commonly used function is imshow(), which displays images in a window. However, users often encounter errors while using imshow(). This tutorial will guide you through common issues and provide solutions.
1. Common Error: cv2.error: OpenCV(4.x.x) ... message
This error occurs when there's an issue with the image data or display window. To troubleshoot, follow these steps:

2. Error: cv2.error: OpenCV(4.x.x) ... (-215:Assertion failed) size.width0 && size.height0 in function 'imshow'
This error occurs when the image dimensions are invalid. To address this, ensure the image is properly loaded and has valid dimensions.
Solution:
3. Error: cv2.error: OpenCV(4.x.x) ... (-215:Assertion failed) scn == 3 || scn == 4 in function 'cv::ipp_cvtColor'
This error occurs when the image has an incorrect number of channels. Ensure the image has either 3 (RGB) or 4 (RGBA) channels.
Solution:
Conclusion:
By following these solutions, you can troubleshoot and resolve common errors encountered when using cv2.imshow() in OpenCV with Python. Always ensure that the image is loaded correctly and has valid dimensions and channels.
