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')
