@akhtarameen were you able to test the suggestions in this post and the associated workflows using [Keras](https://kni.me/w/8pLvXVGL1hj7lXDh) and Conda environment propagation (for MacOSX and Windows)?

> @akhtarameen as it happens I just have collected some example how to set up [Keras](https://hub.knime.com/search?tag=Keras&type=Workflow) and [Tensor Flow](https://hub.knime.com/search?tag=TensorFlow&type=Workflow) 2 (for classification tasks) with the help of the [Conda Environment propagation](https://kni.me/n/7HrPteTMsla4bZml). If you have a working [Miniconda](https://docs.conda.io/en/latest/miniconda.html) or Anaconda environment [configured in KNIME](https://docs.knime.com/latest/python_installation_guide/index.html#configure_python_integration) you should be able to just use the propagation and get a [working deep learning setup](https://docs.knime.com/latest/deep_learning_installation_guide/index.html#_introduction). You would then have to carefully check and plan what you want to d with the setup and what architecture you want to use. 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.
