Question

I installed fastai as explained here in my ubuntu machine https://forums.fast.ai/t/wiki-thread-lesson-1/6825/63
However, when i import libraries, i am getting below error message.
from fastai import *

Can anyone help me on this please? I searched on the internet for hours and didn't find any information. Thanks
