Python SDK installation error

Question

I tried to install Python SDK, using the following command:

pip install predictionio

but I'm getting this error:



 Collecting predictionio

      Found existing installation: pytz 2013.7
        Uninstalling pytz-2013.7:

Also, with easy_install predictionIO, it doesn't gives any error, but then the predictionio module can not be found.
