 passing a ``py_version`` keyword arg to the PyTorch Estimator constructor. Setting this to `py3` (the default) will cause your
 training script to be run on Python 3.5. Setting this to `py2` will cause your training script to be run on Python 2.7
 This Python version applies to both the Training Job, created by fit, and the Endpoint, created by deploy.
