🐛 Describe the bug

I have encountered an issue where usingtorchvision.io.read_image (as well asdecode_image anddecode_gif) on certain GIF files produces an invalid output. Here is a code:

importcv2fromtorchvision.ioimportread_imagegif=read_image('sample.gif').numpy().transpose(0,2,3,1)image=gif[15]# 15-th frameimage=cv2.cvtColor(image,cv2.COLOR_RGB2BGR)cv2.imshow('read_torch',image)cv2.waitKey()

Sample of buggy GIF:

Output:

I understand that this may be an underlying issue ofGIFLIB and will not be fixed. However, since the behavior is unexpected and could impact users, it might be beneficial to include a note in the docs.

Versions

I found this behavior on Macbook and Linux server. They have different setup, but both of them use the latest versions:

torch==2.6.0torchvision==0.21.0
