I'd like to use PyTorch in a Python program. The instructions for installing it require conda. After installing Conda I ran:
>conda install -c pytorch pytorch (as instructed on the PyTorch [page][1])
It looked promising -- until the end.

Apparently it was at least partly installed because PyCharm was able to see it. But when I asked PyCharm to install it in an environment, I got this error.
RuntimeError: PyTorch does not currently provide packages for PyPI (see status at https://github.com/pytorch/pytorch/issues/566).
Please follow the instructions at http://pytorch.org/ to install with miniconda instead.
It suggests an alternative way to install PyTorch. So I tried that.
>conda install pytorch torchvision -c pytorch

To search for alternate channels that may provide the conda package you're
looking for, navigate to
https://anaconda.org
and use the search bar at the top of the page.
But when I do that and search for PyTorch, I eventually find myself back at the original instructions.
When I search for Torchvision, no Windows versions are listed.
