Install pandas to python3.5 instead of 2.7
For Python 3.4.2 Shell, the advice from Timo made the difference:
In the Terminal type
sudo apt-get install python3-pandas
Then in the python shell type
import pandas
and no errors!
I didn't realize that I needed to run pip3 instead of pip. These steps resolved my issue:
sudo apt-get install python3-pip
sudo -H pip3 install pandas
