Unrecognized version of the AdWords API. Version given: v201502 Supported versions: ['v201402', 'v201406']

Hi, just started using the latest library v201502 for Python and I am having issues with the following error:

Traceback (most recent call last):

  File "get_report_fields.py", line 42, in <module>

    main(adwords_client, REPORT_TYPE)

  File "get_report_fields.py", line 25, in main

    'ReportDefinitionService', version='v201502')

  File "build/bdist.macosx-10.9-intel/egg/googleads/adwords.py", line 261, in GetService

googleads.errors.GoogleAdsValueError: Unrecognized version of the AdWords API. Version given: v201502 Supported versions: ['v201402', 'v201406']

I have tried:
   pip install googleads --upgrade 

and it appears to have successfully upgraded but still giving me the same error.

Anything else I am missing?

Thanks,

Stephen
