AttributeError: module 'skimage.measure' has no attribute 'compare_ssim'

This error occurs when you try to use the compare_ssim function from the skimage.measure module, but it is not present in the module. This can happen if you are using an older version of scikit-image or if the function has been removed or renamed in a newer version.

To fix this error, you can try updating scikit-image to the latest version using the command:

pip install -U scikit-image

If the issue persists, you can try using an alternative function or library for image comparison, such as OpenCV or Pillow.
