solves issue #820 on vinta:awesome-python

What is this Python project?

I'm suggesting removal of pylearn2 as per issue #820

What's the difference between this Python project and similar ones?

I'm advocating for removal:

1. Because the project is depreciated, this warning appears on the projects page:

Warning
This project does not have any current developer. We will continue to review pull requests and merge them when appropriate, but do not expect new development unless someone decides to work on it.
There are other machine learning frameworks built on top of Theano that could interest you, such as: Blocks, Keras and Lasagne.

2. As a full time DS practitioner it's my personal professional opinion that this library should not be recommended and the functionality has been completely replaced by more recent and active projects like Keras, pytorch, and many others.
