Update according to Keras 3

[muellerdo]

Hi,

first, thank you for this wonderful package! :)

Since September 2023, Keras has updated to Keras 3 and restructured some of its code base:
https://github.com/keras-team/keras/tree/b9be76a13a1edbea5e17a54bf91da386323222bf/keras

Sadly, due to their updates, the classification_models_3D code is not working anymore on the latest tensorflow/keras version, because the keras.engine submodule does not exist anymore but is required in multiple architectures of classification-models-3D.

See attached the error log:

---------------------------------------------------------------------------

Thank you for your time!

Hello,
This thread is a bit old now, I am sorry to wake it up.
Did you try the recent release 1.1.0? It should be up-to-date with keras 3.

Nicolas
