Neural-Style can be a royal pain in the ass once in a while, the most common error is this first RGB noise that causes the image to burn white then self-implode like a fucking riot gas grenade. It leaves virtual a useless art, sometimes its pretty cool, but most of the times its horrible.
I still cant figure out what is causing it, its not the -learning_rate. So more experimentation is required. which is quite unfortunate.. :|
After 2mins of writing this article, ive found the main problem
Ive had STYLE_SCALE=0.5 and changing it to STYLE_SCALE=1 fixed it..Usally anything from 0.4 and below causes this, but its the first time ive seen 0.5 go bad, odd..
