SMILES Parse Error

[zhangbingfeng]

when I used train_agent.py,This will happen： SMILES Parse Error: syntax error for input: '-2)2GOOc' [10:19:53] SMILES Parse Error: syntax error for input: '()GO(O' [10:19:53] SMILES Parse Error: syntax error for input: '2-212121O' [10:19:53] non-ring atom 0 marked aromatic [10:19:53] SMILES Parse Error: syntax error for input: 'GO2' [10:19:53] SMILES Parse Error: syntax error for input: '(GO' [10:19:53] SMILES Parse Error: extra close parentheses for input: 'O11)-c-c-GOc)((-2c)GO1' [10:19:53] SMILES Parse Error: syntax error for input: 'GOcO-(cGO-2((c--1GO-'

What is the matter, please? Thanks
