UserWarning: Palette images

Part 1 (2020)

Converting PNG (GIF?) images to full RGBA PNG images seems to fix the problem.

I put this code after removing the ‘failed’ images:

for o in bear_types:
    # convert all PNG, GIF images to RGBA
    for image in os.listdir(path/o):
        ext = os.path.splitext(image)[1]
        
        if ext in ['.png', '.gif']:
            new_filename = os.path.splitext(image)[0]+'.png'
            img = Image.open(path/o/image)
            img.convert('RGBA')
            img.save(new_filename)
            print('saving: ' + new_filename)
