错误信息：

Could not decode ‘\xe6\x9c\xaa\xe5\x91\xbd\xe5\x90\x8d‘ for unicode trait ‘untitled_notebook‘ of a LargeFileManager instance.

解决办法：

edit /usr/local/anaconda2/lib/python2.7/site.py file, change the

function def setencoding line 481 from if 0 to if 1, so it will call

sys.setdefaultencoding(encoding)

edit /usr/local/anaconda2/lib/python2.7/site-packages/traitlets/traitlets.py

file, change line 2050, from return value.decode(‘ascii‘, ‘strict‘) to

return value.decode(‘UTF-8‘, ‘strict‘)
