 If you don't have a beefy GPU or just want to crank out a styled image, you have a few options to play with. They all trade detail for speed/memory.
  * set `--patch-size=1` or 2 to consider smaller feature patches (default is 3)
  * set `--mrf-w=0` to skip optimization of local coherence
  * use fewer feature layers by setting `--mrf-layers=conv4_1` and/or `--analogy-layers=conv4_1` (or other layers) which will consider half as many feature layers.
 
 Parameters

-
  * --width Sets image output max width
  * --height Sets image output max height
  * --scales Run at N different scales
