Prerequisite

• CNTK and keras (https://docs.microsoft.com/en-us/cognitive-toolkit/Using-CNTK-with-Keras)
• SimpleITK
• numpy
• scipy.ndimage

CNTK and Keras

If you'd like to use CNTK as Keras backend, don't forget to set the environment variable:

export KERAS_BACKEND=cntk

or update the Keras configuration file:

{
    "epsilon": 1e-07, 
    "image_data_format": "channels_last", 
    "backend": "cntk", 
    "floatx": "float32" 
}

Note that you don't need to change the Keras frontend codes for other backends (tensorflow or theano).

Please be aware that CNTK Keras support is in beta and there're known issues. Check the page and the issue tracker on GitHub.
