Why SMILES length longer than 218 is too long?

[1633232731]

Hello and thanks for publishing the code of your research. while running experiments, I had some questions.

In function get_input(), I notice that when SMILES length is longer than 218 it will print a hint, and I notice your HIV dataset split train set and test set with SMILES length 218. Why 218? Is it a magic number?

Question from a new learner.

As far as I remember, when SMILES was longer than 218, it caused out-of-memory errors in the machine I used. I apologize for the unclear warning message.

Thank you~ That bothers me for a long time. However, it works in my machine when longer than 218
