Python3.4: Upgrade pandas does not work

Question

I use the pre-installed python3.4 on Ubuntu 14 and want to upgrade pandas to version 0.18.0:

import pandas 
pandas.__version__
>>>>\'0.13.1\'


        

Answer 1

I had this same issue (not being able to update pandas via pip3). The problem is installing pandas from two sources (pip3 and apt-get). Try this (it's what I did on ubuntu 16.04):

1. Remove existing pandas:
   • sudo apt-get remove python3-pandas
2. Install via pip3:
   • sudo pip3 install pandas # it installed pandas 0.18

3. Check the correct version a terminal (ctr+alt+t) type:

   • pip3 list # prints out a list of installed python3 modules

   OR / AND

   • python3
   • import pandas
   • pandas.__version__
