我已经使用编码utf-8创建了一个包。

当调用一个函数时,它会返回一个DataFrame以utf-8编码的列。

在命令行使用IPython时,我没有任何问题显示此表的内容。使用笔记本时,它会因错误而崩溃'utf8' codec can't decode byte 0xe7。下面我附上了一个完整的回溯。

使用Notebook的正确编码是什么?

我最近遇到了同样的问题,并且确实将默认编码设置为UTF-8的技巧:

import sys
reload(sys)
sys.setdefaultencoding("utf-8")

运行sys.getdefaultencoding()产生了'ascii'对我的环境(的Python 2.7.3),所以我想这是默认的。
