Troubleshooting: No Module Named Cython with Ipython Notebook

[mahya]

Hi guys,

I want to use the C-extension of Python (Cython) in order to speed up my Python codes. I have already installed the Cython package using the command $ pip install Cython. Now I want to apply the package in Ipython notebook and when I start with the command:

%load_ext cythonmagic

I get the error:
No module named Cython

Could you please help me to get rid of the error?

thanks!
