Resolve package not found about fastai

[stas00]

Here https://pytorch.org/get-started/locally/ it says:

conda install pytorch torchvision -c pytorch
# MacOS Binaries dont support CUDA, install from source if CUDA is needed

Looking at https://www.google.com/search?q=pytorch+macos+cuda the install from source works. and that pytorch has no intention currently to support binaries.

But what I meant in my original reply is that fastai-v1 has no direct dependency on cuda.

fastai-v1 supports whatever pytorch supports (with windows support catching up that is). FWIW, we run a 100% success test suite on CI for MacOS/conda for cpu. MacOS/pip has incompatibility issues between pytorch and numpy. pytorch/pytorch#14359. We have no CI w/ GPU capacity to test with.

If, however, you're referring to fastai-0.7x, then I don't know. I doubt this will ever change since pytorch-0.3 is not being in active development.

I can't help with MacOS sorry. If anyone knows how to get it working on MacOS, a PR would be welcomed.

Ran into a similar issue for MacOS. Cuda90 is not supported on Mac, only on Windows and Linux. You can verify package compatibility by searching https://anaconda.org/

This is a year old thread, and this information is no longer correct.

MacOS is partially supported, i.e. not 100% mainly due to issues in pytorch for which fastai has no control over. e.g, this one: pytorch/pytorch#14359

@stas00 Good to hear. Any idea how to get around cuda90 not being available on MacOS? It's a dependency in the fastai env and it's not supported on MacOS.
