At #68873, @jbschlosser states that maxunpool2d with the output_size argument only works for indices of the same size. This makes sense, but unfortunately it's not what's shown in the example! I've removed the wrong example and replaced it with one where specifying output_size is actually necessary -- the unpool call fails without it.

You can add a comment to the PR and tag @pytorchbot with the following commands:
# ciflow rerun, "ciflow/default" will always be added automatically
@pytorchbot ciflow rerun

# ciflow rerun with additional labels "-l <ciflow/label_name>", which is equivalent to adding these labels manually and trigger the rerun
@pytorchbot ciflow rerun -l ciflow/scheduled -l ciflow/slow
