Check if nose in a list of installed python packages. You can do it in python console (windows + R, type cmd then enter, type python then enter):

>>> help('modules')

If nose is there, then you either have a problem with PYTHONPATH when running your code or you using another interpreter to run console and your code.

If nose not in a list, do in your console (windows + R, type cmd, then enter):

pip install nose
