Getting the same issue - here's the exact error message for others' reference:

python preprocess.py --train data/chembl/all.txt --vocab data/chembl/vocab.txt --ncpu 16 --mode single

The above exception was the direct cause of the following exception:

Found a super easy solution to this problem - just generate a fresh vocab from the dataset rather than using the one provided. I think an rdkit update changed a couple of the ways the smiles strings are generated, particularly from the aromatic groups (this was mentioned in another issue thread).
