Problems installing via pip

[robhoney]

When installing via pip, the install works, but once I run it (hydra-server run) I get problems. The first of these is in spyne:

Traceback (most recent call last):
  File "c:\users\honeywillrs\appdata\local\continuum\anaconda3\lib\runpy.py", line 193, in _run_module_as_main

SyntaxError: invalid syntax

Using the version at git://github.com/arskom/spyne.git@spyne-2.13.2-alpha#egg=spyne as suggested by @knoxsp fixes this problem, but another issue manifests itself:
