Given that is not acceptable for our datasets to drop any sample, we need to use an infinite buffer size in all datapipes that have a variable sized buffer. This PR adds a test that enforces this.
Currently we use
vision/torchvision/prototype/datasets/utils/_internal.py
Lines 42 to 43 in 1db8795
but that hopefully changes after pytorch/data#335 is resolved.
