Runtime error with Ogre

[amritachattopadhyay]

Hi Ogre developers,

I am interested in using Ogre 1.1 in my research. I have managed to download and install the software from https://www.noamarom.com/software/download/

However, when running Ogre using the command python runOgre.py --filename ogre.config
, I run into this error:

Traceback (most recent call last):

Any help will be greatly appreciated, thank you very much.
