Train fail

[GilbertTam]

Hello, Have you face the same problem below?

File "train.py", line 306, in sample(ep, it) File "train.py", line 251, in run im.imwrite(sample, '%s/Epoch-%d_Iter-%d.jpg' % (save_dir, epoch, iter)) ... 'images should be in the range of %s!' % (l + ',' + r) AssertionError: images should be in the range of [-1.0,1.0]!

It's my download data problem?

@GilbertTam What modification did you made?

[GilbertTam]

I just run train ,no parameters change when epoch is 15 will fail

[LynnHo]

@GilbertTam Do the images in the output folder make sense? I just rerun the code but haven't got any error.

hi,i have the same problem,no parameters change. run in cpu mode,It's problem?

python 3.6.9 tensorflow-gpu 1.15.0 cuda 10.2 cudnn 7.6

On this issue,I changed it here ,Then it run.

# File "train.py"
# run(epoch, iter)
try:
    im.imwrite(sample, '%s/Epoch-%d_Iter-%d.jpg' %
                       (save_dir, epoch, iter))
except:
    print('ERROR: Could not save %s/Epoch-%d_Iter-%d.jpg' %
                  (save_dir, epoch, iter))

@millionsofluo I am still confused by this problem. Is there any good results in the output folder.

[millionsofluo]

@LynnHo Yes,This folder has good results,Very strange.
