Hi @deganza,
yes, unfortunately there is no support for using the Keras-based deep learning integration in KNIME on Apple Silicon. The reason is that this deep learning integration was built with Tensorflow 1 (hence the warning that 2.0.0 is the “exclusive” maximum version). However, Apple Silicon support for Tensorflow was only added in Tensorflow version 2.5 (see e.g. the conda packages provided by Apple: Files :: Anaconda.org).
In the meantime, we have made a lot of improvements to the KNIME Python integration in general, so the best way forward would be a new KNIME Keras deep learning integration based on the new Python integration. Unfortunately I cannot promise any dates when this would happen.
What you can try in the meantime is to use the KNIME TensorFlow 2 extension, because we have seen it working with Tensorflow 2.10. But that extension is not as feature-rich as the KNIME Tensorflow 1 extension.
Hope that helps,
Carsten
