UnicodeEncodeError : 'ascii' codec can't encode character u'\xd7' while saving and accessing Jupyter notebook

问题

I am running a Django(Python 2.7) application with IPython notebook in a docker container and for some notebook, while accessing I am getting Error of An unknown error occurred while loading this notebook when I check logs it's showing

UnicodeEncodeError: 'ascii' codec can't encode character u'\xd7' in position 14: ordinal not in range(128)

The same problem is happening when I am saving a file with the shape of the data frame Row X column problem was with the parsing of X(u'\xd7') Unicode.

Tried changing sys encoding noting happened

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

nbformat==5.0.x requires python 3.5+

Starting with 5.0, nbformat is now Python 3 only (>= 3.5)
