'python' engine because the 'c' engine does not support regex separators

2018-10-2 杜世伟 Python

moveielens.py:17: ParserWarning: Falling back to the 'python' engine because the 'c' engine does not support regex separators (separators > 1 char and different from '\s+' are interpreted as regex); you can avoid this warning by specifying engine='python'.
  user = pd.read_table(path1, sep='::', header=None, names=unames)

  pandas.read_table()函数，读取文件数据时，由于分隔符为'::'，弹出如下警告
       警告：ParserWarning: Falling back to the 'python' engine because the 'c' engine does not support regex separators (separators > 1 char and different from '\s+' are interpreted as regex)
       解决方法：增加函数的引擎参数engine='python'，如下：

    user = pd.read_table(path1, sep='::', header=None, names=unames, engine='python')
