I am trying to plot a bar. But it shows Runtime error, and shows In FT2Font: Can not load face. at the Botton. I have tried uninstall and install it again. And tried another method, but still can not work. I think the code is right, because I successfully run it on a windows laptop. And my jupyter notebook is for Mac python 2.7.
The code is as following:
import numpy as np
import pandas as pd
obj = pd.Series([4, 7, -5, 3])
print type(obj)
obj
%matplotlib inline
obj.plot(kind = 'bar', figsize=[5,4])
But it shows some error :
<matplotlib.axes._subplots.AxesSubplot at 0x1114e69d0>

I was facing same issue while using anaconda and spyder with python 3+ on MacOS. I am not sure if this solution would work for you but i solved it by deleting all files and folder in:
/Users/YOUR_USER/.matplotlib
and then uninstalling and reinstalling 'matplotlib' from my environment in Anaconda Navigator.
