Style.py: Question about Python version and operating system

Hello,

i just try to get this style.py thing running, and it trains without any error message. Unfortunately, the outputs look wrong and it seems that the algorithm is converging to a weird state.

This is an example images i get after training for around 1 hour on a geforce 1080 TI: (content = chicago.jpg, style = la_muse.jpg)

I already tried to resize the style and content image to 224x224 pixels but it did not help.

What could be the reason behind this bad results? Do i need a linux system to get this running? Can i use python 3.7 , and should it work for tensorflow 1.15.0 ? If someone has some information for me, would be really cool! Thank you!
