Which of the following is the best lasagne, keras, pylearn2, and nolearn deep learning libraries?

the difficulty of getting started with deep learning algorithms .. in other words, it is a silly call. In fact, almost all of them are used. I remember that this year's Deep Learning summit in London had a great opportunity to get a class comparison chart of the python library (searching for the source image...). I c

bit, the Python-based library actually has a decaf , this is called more thoroughly than PYLEARN2 abandoned building stop development (escape do not know which home the strongest, only know pylearn2 the worst. It took about one months to learn, it was a nightmare, fortunately stopped development. First of all, Pylearn2 can also be ranked among them ... The main topic is Baidu has a hundreds of years ago, "experience post" it. Second, the main question is "which library to use." If from the "Lo
