Update needed for PyTorch changes

[alo9507]

Running the notebook shows the following warnings/errors related to recent changes in PyTorch:

/opt/anaconda3/lib/python3.7/site-packages/torch/optim/lr_scheduler.py:82: 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.See more details at https://pytorch.org/docs/stable/optim.html#how-to-adjust-learning-rate "https://pytorch.org/docs/stable/optim.html#how-to-adjust-learning-rate", UserWarning) /opt/anaconda3/lib/python3.7/site-packages/torch/nn/functional.py:2479: UserWarning: Default upsampling behavior when mode=bilinear is changed to align_corners=False since 0.4.0. Please specify align_corners=True if the old behavior is desired. See the documentation of nn.Upsample for details. "See the documentation of nn.Upsample for details.".format(mode))

I'm also experiencing this error, did you manage to make it work?
