How to create a custom Caffe layer in Python?

This tutorial will guide through the steps to create a simple custom layer for Caffe using python. By the end of it, there are some examples of custom layers.

- Why would I want to do that?

Usually you would create a custom layer to implement a funcionality that isn't available in Caffe, tuning it for your requirements.

- What will I need?

Probably just Python and Caffe installed.

- Is there any downside?

# A little demo illustrating the effect of momentum in neural network training.
# Try using different values for MOMENTUM constant below (e.g. compare 0.0 with 0.9).
# This neural network is actually more like logistic regression, but I have used
# squared error to make the error surface more interesting.
