ValueError: too many values to unpack

What's this error caused by, and how do I resolve it?

[brade31919]

I think the reason is that I assumed there would be only gray scale and color image. Therefore, I simply check whether the last dimension is 3 or not. Can you provide im.shape when the error message occurred so that I can take it into consideration?

[ProGamerGov]

Using ImageMagick I figured out that the input image I was trying to use, had an sRGB color space instead of an RGB color space.

To solve this issue in another project, I used code like this:

import scipy.ndimage as spi

spi.imread(org_content, mode="RGB").astype(float)/256

to make sure that every input image was read as an RGB image.

My fix used the scipy library:

sudo pip install scipy

Maybe something like my fix with scipy, could work for SRGAN-tensorflow?

Maybe I can add it into SRGAN later. Still busy now@@
