你好 我是新人 想学习一下你的代码 运行extract_feature.py出现问题 报错如下
Traceback (most recent call last):
File "extract_feature.py", line 60, in
feature3 = off_train[((off_train.date>='20160315')&(off_train.date<='20160630'))|((off_train.date=='null')&(off_train.date_received>='20160315')&(off_train.date_received<='20160630'))]

File "C:\Users\u\AppData\Roaming\Python\Python36\site-packages\pandas\core\ops.py", line 818, in na_op
raise TypeError("invalid type comparison")

on_train = pd.read_csv('data/ccf_online_stage1_train.csv',header=None, keep_default_na=False)
在使用pd 读取csv的时候 加上参数 keep_default_na = False
