pytorch warning about misordered optimize and lr schedule

[jlquinn]

/u/jlquinn/jlquinn-mt/gaama/conda.x86/envs/de-sbd/lib/python3.7/site-packages/torch/optim/lr_scheduler.py:143: UserWarning: Detected call of lr_scheduler.step()beforeoptimizer.step(). In PyTorch 1.1.0 and later, you should call them in the opposite order: optimizer.step()beforelr_scheduler.step(). Failure to do this will result in PyTorch skipping the first value of the learning rate schedule.
