The python package, coremltools, to convert the trained model is only for python 2.7??
A bit disappointed that the model conversion tool only supports an older version of Keras as well (1.2.2). Keras 2.0 is pretty new but I hope they update the conversion tools for it quickly ...
I wonder if the conversion tool will be open source ... seems like they'd want to support the widest net of external models since they don't yet have a way to produce .coreml models directly. Or maybe the intent is to augment Keras/caffe/etc to support saving .coreml directly?
Right now, coremltools is only available for Python 2.7 (https://pypi.python.org/pypi/coremltools), which is annoying as the entire code base I've worked on for months at my current firm is in Python 3.6. Hopefully this is updated soon for Python 3 support.
