Hello, I have a related problem with my submission in non-debug mode:
using my code I can process all the smiles stings of the train set, but once the program runs on the set of the non-debug submission the code fails to process some of the strings.
I suspect that the error is probably due to some special char in the test set smiles (like a backslash), in any case I find very strange that this error don’t show up for any of the smiles in the train set and multiple times during the test
