The new Python script node does not handle for Example SMILES input in a usable manner.
If we do
df = knio.input_tables[0].to_pandas()
print(df['SMILES'].iloc[1])
we get below output:
{'0': {'0': 1, '1': b'\x02 \x00\x00\x00org.knime.chem.types.SmilesValue\x1f\x00\x00\x00org.knime.core.data.StringValue\x04\x00\x00\x00CCCO\x00'}, '1': {'0': 0, '1': None}}
Expected would be simply a string with the smiles value (CCCO). Therefore if using this node any smiles column must first be converted explicit to a string value. Then it works.
(Yes theoretically the smiles value could be extracted from above output but…)
I did not check for other column types but I expect same issue for molfile columns or other chemical format columns.
