keras.layers.TimeDistributed with hub.KerasLayer NotImplementedError

Question

I want to use tf.keras.TimeDistributed() layer with the tf.hub inception_v3 CNN model from the latest TensorFLow V2 version (tf-nightly-gpu-2.0-preview). The output is shown bel

Answer 1

In Tensorflow 2 it is possible to use custom layers in combination with the TimeDistributed layer. The error is thrown because it can't compute the output shape (see here).

So in your case you should be able to subclass KerasLayer and implement compute_output_shape manually.
