cv2.error: OpenCV(4.10.0) 👎 error: (-5:Bad argument) in function 'imread'

Overload resolution failed:

  • Argument 'flags' is required to be an integer
  • dst is not a numpy array, neither a scalar
  • Expected Ptrcv::UMat for argument 'dst'

The error speaks for it self:

Specific Error Message

  • OpenCV Error: cv2.error: OpenCV(4.10.0) error: (-5:Bad argument) in function 'imread'
    • Bad Argument: This indicates that the argument passed to cv2.imread is not valid.

Common Causes

  • Invalid File Path: The image_path passed to cv2.imread might be incorrect or the file does not exist. cv2.imread returns None if the image path is invalid.
  • Incorrect Data Type: The image_path should be a string representing the path to the image file.
  • File Access Issues: There might be permission issues preventing the file from being read.
  • Unsupported File Format: The image format might not be supported by OpenCV.

So, check if what file you try to read with openCV and try to investigate this specific file
