TorchSharp is a .NET library that provides access to the library that powers PyTorch. It is a work in progress, but already provides a .NET API that can be used to perform various operations on Tensors.

Our current focus is to bind the entire C API surfaced by libtorch.

Things that you can try:

using TorchSharp;

var x = new FloatTensor (100);   // 1D-tensor with 100 elements
FloatTensor result = new FloatTensor (100);

FloatTensor.Add (x, 23, result);

Console.WriteLine (x [12]);

We have a chat room here:

https://gitter.im/xamarin/TorchSharp

Currently I am binding the Tensor APIs, opportunities to bind other APIs are wide open.

API Documentation

To run this, you will need libtorch and its dependencies (on Mac that includes libc10) installed in a location that your dynamic linker can get to.

The following was tested on Ubuntu 18.04 on the Windows Subsytem for Linux.

1. Install the .NET Core SDK.
2. Install libtorch, and make it available to the dynamic linker.
3. Run dotnet run in the Tester subfolder.
