Keras - Python
Keras If you like the Python-way of doing things, Keras is for you. It is a high-level library for neural networks, using TensorFlow or Theano as its backend. The majority of practical problems are more like: picking an architecture suitable for a problem, for image recognition problems – using weights trained on ImageNet, configuring a network to optimize the results (a long, iterative process). In all of these, Keras is a gem. Also, it offers an abstract structure that can be easily converted to other frameworks, if needed (for compatibility, performance, or anything).
