Python 1=>2 node display error for molecules

Okay.
I figured out the following:
the rdkit molecules make KNIME crash…as described here: Forum post

Nevertheless

  1. the rendering issue for the second output is still weard and
  2. the above error: Execute failed: ‘Series’ object has no attribute ‘ToBinary’

Sorry if the post is messy. I am willing to split, move or rewrite it if necessary.
