UserWarning: This overload of nonzero is deprecated: nonzero()

[eugeneware]

I continually get this warning while training with the latest fastai2 library and pytorch 1.6.0 and torchvision 0.7.0 and git commit 2b19225. Happens with the first first notebook in the fastbook repository.

Here's the warning.

/home/fastai/fastai2/fastai2/callback/schedule.py:68: UserWarning: This overload of nonzero is deprecated:
    nonzero()
Consider using one of the following signatures instead:
    nonzero(*, bool as_tuple) (Triggered internally at  /opt/conda/conda-bld/pytorch_1595629427478/work/torch/csrc/utils/python_arg_parser.cpp:766.)
  idx = (pos >= pcts).nonzero().max()
