@sfoglia the point is to find the exact combination of python versions and packages that would work with the knime deep learning integrations. And they might be different depending on you use of keras, or Tensorflow 1 or 2.
The description could try and make that more obvious and also more clearly provide yaml files about what knime would want to have.

I tried to distill what is there into Conda Environment propagations for several scenarios on windows and Python.
@bwilhelm it would be great if the knime deep learning example could come with their own environment propagation (maybe even for Windows, Mac and Linux) and also for the deep learning guides to be more exact and maybe provide explicit yaml files for the knime nodes. Often you find circle and cross-references that can be confusing.
The latest knime version 4.6 offers a confirmation specifically for python deep learning- @sfoglia maybe you check this out.
