Pyro: Pyro minor release 0.3.1

[neerajprad]

Task-list:

• [x] Remove networks x from dependency. #1736
• [x] Update setup.py and .travis.yml to use PyTorch 1.0.1
• [x] Fix CUDA tests.
• [ ] Address issues for next release:
  
  
  
  • [x] Progress bar fixes in mcmc: https://github.com/pyro-ppl/pyro/issues/1728
  
  
  • [ ] ~Abstract infer classes lazily consume traces: https://github.com/pyro-ppl/pyro/issues/1725. (not a blocker)~
  
  
  • [ ] ~Sample from collapsed latent variables in conjugate distributions. (not a blocker)~
  
  
  • Any other?
  
  

Please feel free to add to the list if we think there are certain fixes (or features, though prioritizing on fixes) that should make it into this release.

Are there any other easy performance wins along the lines of #1736 we could include?

I suggest we update travis to use PyTorch 1.0.1 but keep setup.py permissive via torch>=1.0, since Pyro doesn't require anything in the new PyTorch release.

I can't think of much at the moment. There's the issue of TracePosterior being lazy for MCMC that I mentioned above, but that's a narrow use case that will help multiprocessing.

Is everyone good with releasing a minor version with the current dev branch?
