Pillow Version 7.0.0 ValueError image is wrong mode

[clkotnik]

I had a program running for awhile that used Image.resize(size) with defaults for other parms. I installed the program on a new system with Pillow installed as default version 7.0.0. The resize failed with Value Error image is wrong mode.

I removed Pillow and forced version 6.2.1 to install and the program works as before.

What version of torchvision are you using? The release of pillow==7.0.0 broke torchvision==0.4.2 (#1714), but it should be fine for the latest release (torchvision==0.5.0). If that is not the case, please post a small example how to reproduce your error.

I do not use torchvision.

Here is a simplified example:

import numpy as np
from PIL import Image
imgdata = np.array( [[484, 451, 481, 465, 488, 442],
[823, 897, 971, 920, 855, 908],
[758, 919, 854, 920, 850, 854],
[840, 873, 950, 893, 872, 881],
[937, 940, 835, 879, 895, 774],
[841, 914, 867, 886, 922, 952]]).astype(np.uint16)

pimg = Image.fromarray(imgdata)
scale_factor = 0.5
size = tuple((np.array(pimg.size) * scale_factor).astype(int))
newim = pimg.resize(size)

Sorry, I seem to have drifted from Pillow to pytorch within github. Please disregards, I posted this to Pillow.
