Hi all, I’m a new user of KNIME. I’d tried to create a workflow for calculating QED for drug design. After, including the Python script, from rdkit import Chem from rdkit.Chem import Descriptors from rdkit import rdBase, RDConfig import sys, os sys.path.append(os.path.join(RDConfig.RDContribDir, ‘SA_Score’)) import sascorer qeds = sas = for mol in input_table[‘mol’]: qeds.append(Descriptors.qed(mol)) sas.append(sascorer.calculatescore(mol)) output_table = input_table output_table[‘qed’] = qeds output_table[‘sa_score’] = sas print (output_table.head ()) I’m getting the following error “Executing the Python script failed: Traceback (most recent call last): File “”, line 10, in , NameError: name ‘input_table’ is not defined” I’m using Python 3.9.16… It seems I could not call input from knio.input_table[0] to python environment Can you give suggestions to fix it? Thanks

Executing the Python script failed: NameError: name 'input_table' is not defined

@gurudeeb_knime welcome to the KNIME forum. It seems your node is configured to expect an input table. You might have to provide one or delete the port:
