A problem while I run preprocess.py

[ZoeyChen]

when I run preprocess.py, I meet a problem.
Traceback (most recent call last):
File "preprocess.py", line 9, in
from fast_jtnn import *
File "/home/zhai/cxh/icml18-jtnn/fast_jtnn/init.py", line 1, in
from mol_tree import Vocab, MolTree
ModuleNotFoundError: No module named 'mol_tree'
But I add export PYTHONPATH=$PREFIX/icml18-jtnn to my environment variables.
