Unable to reproduce example

[AndreaBaroni92]

Hi,
thank you for sharing your code.
When i try to reproduce sailboat_cropped.jpg in the folder : images/content/ with style sketch_cropped.png in the folder images/style/ with the command (with python3):

python style.py --log-dir model/ --content-image images/content/sailboat_cropped.jpg  --style-image images/style/sketch_cropped.png  --output-image images/output/ris1.jpg  --alpha 1.0

i got this:

Also i dont' understand why, when you feed the content and the style images in the encoder you call vgg19.preprocess_input
but in the decoder there is not any operation for doing the inverse of vgg19.preprocess_input.
Thank you.
