Cannot import sentinelsat python module

I am a python newbie and am trying to get the sentinelhub module to work but have been receving this error message on my code:

import sentinelhub

Traceback (most recent call last): File "<pyshell#0>", line 1, in import sentinelhub ImportError: No module named sentinelhub

After I've downloaded the module using "pip install sentinelhub" on the windows command. I am currently using Python version 2.7.18. Any suggestions would be helpful. Thanks.
