problems in importing theano

Question

I am running python on windows but when I import theano, I come across this problem:

import theano

WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to execute optimized C-implementations (for both CPU and GPU) and will default to Python implementations. Performance will be severely degraded. To remove this warning, set Theano flags cxx to an empty string.

To remove this, just install g++ or do as it very clearly says:

To remove this warning, set Theano flags cxx to an empty string.
