Description

This PR disables the multiprocessing dataloader in the tensorboard tutorial because enabling the multiprocessing dataloader (num_workers=2) caused a runtime error when running the tutorial code on mac.

This PR also ignores a deprecation warning from tensorboard as tensorboard isn't actively fixing it (tensorflow/tensorboard#7003).
