Python 3.6.1 64位和Python 2.7.13 64位都试过了，都有这个error

错误信息如下
Traceback (most recent call last):
File "train.py", line 82, in
xgboost_make_submission()
File "train.py", line 18, in xgboost_make_submission
user_index, training_data, label = make_train_set(train_start_date, train_end_date, test_start_date, test_end_date)
File "D:\jd-master\gen_feat.py", line 272, in make_train_set
user = get_basic_user_feat()
File "D:\jd-master\gen_feat.py", line 46, in get_basic_user_feat
user = pickle.load(open(dump_path))
TypeError: a bytes-like object is required, not 'str'

把dump_path改成dump_path.encode("utf-8")也没用，一样的错误= =
