成功解决pandas\core\frame.py:2754: SettingWithCopyWarning: A value is trying to be set on a copy of a s
解决问题
pandas\core\frame.py:2754: SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame
解决思路
发生在pandas\core\frame.py文件内,
设置复制警告::试图在DataFrame切片的副本上设置一个值。其实,这是Pandas的API改了使用方法。
请参阅文档中的警告:http://pandas.pydata.org/pandas-docs/stable/indexing.html#indexing-view-versus-copy
self._update_inplace (new_data)
