CoreML - Cannot perform conversion from Keras to CoreML - Windows 10

I recently upgraded my keras from version 1.1.0 to 1.2.2 and I ran a CNN for hand gesture classification (the code was developed using keras 1.1.0). I saved the trained model and I tried to convert it to CoreML model using coremltools. The code is as shown below:

import coremltools
import theano
from keras import backend as K
K.set_image_dim_ordering('th')

coreml_model = coremltools.converters.keras.convert('hgm_2.h5')
coreml_model.save('hgm.mlmodel')

But it gave me the following error:

RuntimeError: keras not found or unsupported version or backend found. keras conversion API is disabled.

How can I fix this issue? I tried upgrading theano, but it gave the same error.

Solution

  • I have received a reply here. Currently the conversion is not supported for theano backend.
