Simple Python Package to Extract Deep Learning Features

Dunno, maybe you aren't the target for the article. As someone who has never played with deep learning, I thought it was presented just fine.

it is a lot harder than what this library does.

Please provide either an example or a source for this assertion.

The OP library specifically grabs the ImageNet model and uses transfer learning. That's just a general keras convolutional networks resource.

The entire library is only 100 lines of code, so you could copy and paste its own source.
