Python 3.5 Jupyter Notebook ggplot "name error"

Question

I am getting NameError: name 'unicode' is not defined when using yHat's ggplot library for Python (see full error below) in a Jupyter Notebook, running Python 3.5.2. with the following import statements:

 %matplotlib inline
from ggplot import *

The graph still renders, but I would like to eliminate the error, or hide it if its not causing a major conflict.

The full error is below. Many thanks in advance :)

It's probably not py3 save: github.com/yhat/ggplot/blob/… -> The tests are also not py3 save, so I guess it is py2 only... — Jan Katins

If you have anaconda installed try installing the code-forge version. I was able to fix this same problem by switching to that version for python 3.5

conda install -c conda-forge ggplot

Hope that helps

Thanks, I will try this. I ended up adding in the Python 2.7 kernel for Jupyter, then ran ggplot on 2.7 instead of 3.5.2
