Some creepy feature extraction code I found attached to a research paper.

Features:

  • the "pretrained" parameter it's not actually used.
  • Just works (not so sure about that) with a vgg16, what if I want to use any other model?
  • They provided a spare copy of line 12, in case you lose one.
  • You can select a custom combination of layers by uncommenting the right if statement. A chinese explanation follows. Sometimes.
  • Why use pytorch hooks when you can write a 20+ lines class each time you need it?
