run test_trans.py error

[tanjia123456]

hello, when I run the test_trans.py, the error message occurs:

File "F:/googledownload/planetoid-master/test_trans.py", line 49, in OBJECTS.append(cPickle.load(open("data/trans.{}.{}".format(DATASET, NAMES[i]),"rb+"))) UnicodeDecodeError: 'ascii' codec can't decode byte 0x85 in position 16: ordinal not in range(128)

do you know how to solve it? my python version is 3.6
