Confusion regarding DiffSharp-cuda-windows bundle

See original GitHub issue

I can’t get the DiffSharp-cuda-windows bundle to work. Three things that confuse me:

  1. It depends on libtorch-cuda-10.2-linux-x64 (rather than libtorch-cuda-10.2-win-x64), which naturally doesn’t contain the necessary DLLs to run under windows
  2. Any attempt to restore it seems to fail, and I don’t understand why; the DiffSharp-cpu bundle restores just fine, and looks mostly the same. The error is “Package ‘DiffSharp-cuda-windows’ is incompatible with ‘all’ frameworks in project”. This doesn’t seem to be transient or machine specific problem, but I don’t understand it, so it might just be me.
  3. It targets netcoreapp3.0; I’d have expected it to be netstandard2.1 (per the nuspec); however, I see this was explicitly changed recently, so I assume there is a reason for this.

On a positive note, I have successfully got CUDA/GPU working under windows by manually adding the following dependencies (the newly added CI builds on nuget):

  • DiffSharp.Backends.Torch Version=“1.0.0-preview-243323135”
  • DiffSharp.Core Version=“1.0.0-preview-243323135”
  • libtorch-cuda-10.2-win-x64 Version=“1.5.6”

Incidentally, I’m probably going to end up using DiffSharp for significantly more work in the near future, and I recall something about testing under Windows GPU being a problem: I’d be happy to put some effort in if it’s something I can help with (my main machine is Win 10 with an RTX 2060 Super).

Took another stab at this here, and actually tested it locally this time. Will also re-test once the packages get to
