Does MorphNet support conv3d? about morph-net HOT 3 OPEN

Sorry, I found the mistake in my code.
For fully connected layer, network_regularizer should be GroupLassoFlopsRegularizer.

Dear not a big fish,

I am sorry to say that for now MorphNet does NOT support conv3d.

What you have observed is the op_regularizer_manager that looking for an op called FusedBatchNorm and unfortunately for 3d convolutions this op does not exist. So it appears there is nothing to regularize. Further more, even without batch norm, the cost calculator will need to change in order to correctly handle this case.

Furthermore, It is true that fully_connected layers are regularized via GroupLassoFlopsRegularizer but again this is not what you want, as the logits have a fixed dimension (number of labels, 10 in your example), and therefore there is nothing to learn here. This is always true for the last layer of the network, regardless of if its a fully connected or a conv layer.

We are planning to support Conv3D in the near future but I don't have an exact date. If you would like to contribute and try to code it, we will be happy to share with you the way we see this implemented.

Stay tuned,

Dear Elad,

thanks for the detailed explanation. I appreciate this opportunity and would like to try to contribute. Honestly I really don’t know what the first move should be and I’d love to hear your ideas.
