Error while trying to execute .robot file using robot.run - robotframework

Question

I am trying to execute Run_Keyword.robot made with RIDE file which is in directory 'Robot' from python interpreter and getting following error. I am able to run this .py file from cmd without any error and it gives expected results.
What can be the reason for this. I am a newbie to Robot Framework. Please help with this.
from robot import run
run(suite = 'Robot')
The Error I am getting is as follows.
Traceback (most recent call last):
