[Rdkit-discuss] Capturing warnings

[Gerebtzoff, G. <gre...@ro...>]

Hi List,

Is there a clean way to capture the warnings generated by RDKit, for instance "Warning: ring stereochemistry detected. The output SMILES is not canonical"?
I tried several approaches (the warnings python module, by redirecting the stderr with os.devnull, or try/except) but none of them allowed me to capture these warnings.

Many thanks for your advices!

Best,

Grégori
