Hm, strange, the Cheetah package on my PC is definitely written with capital C and can't be imported with small c.
How did you install your Cheetah?

Best regards,

Hey Rohit,

"import Cheetah"

^ the capital C is important, which is why I expliticly asked you to copy and paste the command.

and after doing this still same error.

i want to enhance the filter design tools and adding some support to it. I am interested in this bcoz i have got some strong dsp , asp and signals and systems background. Also i can work on python.
I am participating in gsoc16. since i am rookie to gnuradio so facing the problem. 
but to be honest gnuradio support for windows is poor.

Hi Rohit,

can you make sure to use the "reply" button in your mail client to

clients can show your discussion on the mailing list as one thread,
making it far more probable you'll get a good answer!

Point is that your output [1] shows:

Which means that even if it was installed, it can't be found.
Can you open a shell in the build directory, and run

python -c "import Cheetah;print Cheetah.Version"

there (please make sure to copy and paste the ".." string correctly)?

If python tells you the module could not be found, you didn't install
Cheetah to a directory that python automatically searches for modules.
In that case, you might need to amend the PYTHONPATH environment variable.

Just a note: I'm absolutely no expert on building GNU Radio on Windows.
As a matter of fact, I don't even know whether or not GNU Radio on
Cygwin works at alll!

So, my usual approach here is to take a step back and ask: Why are you
doing this?
