Python读取表格分界符不对

其实就是书上的代码，我用的代码是，下面酱紫

import pandas as pd
unames = ['user_id','gender','age','occupation','zip']
users = pd.read_table('ml-1m/users.dat' , sep = None, header = None , names = unames)

提示这个错误，ParserWarning: Falling back to the 'python' engine because the 'c' engine does not support regex separators

有人说是表格分界符不对。然后改成 

sep = None

更加报错，坑人的度娘。解决方法：加上 engine=‘python‘

就可以了。
