Format JPEG-PIL cannot read in I mode

This error message usually occurs when you are trying to open an image file in JPEG format using the Python Imaging Library (PIL) in "I" mode, which is not supported by the library.

To fix this error, you can try opening the image file in a different mode. For example, you can use "RGB" mode to open a JPEG image file like this:

from PIL import Image

image = Image.open('your_image.jpg').convert('RGB')

Alternatively, you can use a different library like OpenCV or scikit-image to read the image file in a supported mode.
