Add CNTK as keras backend #6800
This is the Beta version of CNTK as keras backend. Those changes are suppose to work with CNTK v2.0 GA. Because the CNTKv2.0 is not officially published, you could use the wheel below to have a first try:
Most of the keras features are supported, except:
I have applied a few style fixes to the backend source and merged. Thanks a lot!
While going through the backend code, I have noticed that a lot of the error messages raised were not as helpful and as clear as they should be. I suggest you go over the error messages and improve them. Typically you want to tell the user: 1) what they did (e.g. print the arguments they passed), 2) why that was wrong (e.g. something not supported), and 3) what they should do instead. Currently you are mostly doing 2) only.
This will greatly improve the user experience for CNTK Keras users, and improve the usability / ease of debugging of Keras models on CNTK.
