CoreMLTools crash Python when converting Keras (.h5) model

Hi there,

I have been trying to convert a Keras trained model (.h5) to a coreMLModel .mlmodel.

Everytime I run this code, python crashes unexpectedly:

import coremltools

coreml_model = coremltools.converters.keras.convert('second_try.h5')
print ('Done')


coreml_model.save('second_try.mlmodel')

'Done' is not printed, hence the converter seems to crash.

Any ideas where I am going wrong?

I tried converting other Keras models and am experiencing the same crash.

I am using Keras 2.0.6 and tensorflow 1.2.1

Many thanks!
