"An error occured during training of the Keras deep learning network" when using KNIME

[mlauber71]

@akhtarameen were you able to test the suggestions in this post and the associated workflows using Keras and Conda environment propagation (for MacOSX and Windows)?

AttributeError: module ‘keras.optimizers’ has no attribute ‘Adam’

@akhtarameen as it happens I just have collected some example how to set up Keras and Tensor Flow 2 (for classification tasks) with the help of the Conda Environment propagation. If you have a working Miniconda or Anaconda environment configured in KNIME you should be able to just use the propagation and get a working deep learning setup. You would then have to carefully check and plan what you want to d with the setup and what architecture you want to use. [image] [image] The setup in …

If this does work initially as @Kathrin has suggested it would be interesting to see your setup and especially the build-up of the network. If you could share that someone might be able to have a look.
