ValueError: image has no palette when show GIF #8921
Description
What did you do?
from PIL import Image import io image_1 = '/Users/fangzidong/git_repo/mmwrastra/debug_data/debug_gif_img/no_palette.gif' with open(image_1, 'rb') as f: image_bytes = f.read() image = Image.open(io.BytesIO(image_bytes)) image.show()What actually happened?
I got this error when i opening this image:
