There exist TorchSharp that is a С# wrapper around the same libtorch.dll that is wrapped by Python code in PyTorch, https://github.com/dotnet/TorchSharp. Though I don't know how exhaustive it is.

In Python, we need to use Numpy to do a large amount of data processing, complete matrix operations, and multi-dimensional data conversion. NumSharp is an open source .NET Core version of Numpy provided by a third party. (Github https://github.com/SciSharp/NumSharp)
Not serious: performance of an extreme monster class

https://github.com/SciSharp/NumSharp/tree/master/src/NumSharp.Core/Backends/Default This is a monster class I wrote, a backend engine of Python's numpy ported to pure C#. Around 300k lines (mostly generated) Visual studio has no issues opening it but Rider and Resharper crash after 10 minutes of use after opening any of the partial files which will work if you turn of Solution-Wide Analysis.
