RuntimeError when uploading image

yopox commented 4 years ago

When I upload this image (32x32 .png) using english or russian colab, I get the following error:

mario.png(image/png) - 2858 bytes, last modified: n/a - 100% done

Saving mario.png to mario.png

Acurisu commented 4 years ago

If I'm not mistaken, does it expect three channels (RGB) while your PNG contains an additional (probably alpha) channel thus leading to four channels (RGBA) which it cannot handle.

Convert your image to jpg or remove the additional channel from your png for it to work.

Fixed it)

Here's what was missing: face = face.convert('RGB')
