I am trying to run parser from here, but it gives this error:

This program requires jinja2 version 2.7 or later

I have already installed the jinja2 package by running sudo apt-get install python-jinja2. Can anyone tell me what I'm doing wrong (with a little guide to run the tool as well)?

The m5out folder is here, with the stats for a ARM core simulation, so you don't have to install gem5 to get those two files required by the script.
