Using TorchSharp In Unity

[StefanWRL]

I am trying to use the latest TorchSharp in my Unity project.

I keep running into this error: NotSupportedException: This application or script uses TorchSharp but doesn't contain a reference to libtorch-cpu-win-x64, Version=2.4.0.0.

I have TorchSharp and libtorch-cpu-win-x64 packages installed with Nuget for unity. I have also tried doing this manually with the same results.

Thanks for any help!

VisualStudio 2022
Pytorch 2.4.0+cpu
Python 3.9
libtorch-cpu-win-x64 2.4.0.0
TorchSharp 2.4.0.0

Perhaps eventually we may need a documentation on Torchsharp in Unity, involving how onnx could be used in some cases.

Maybe someone could compile this to a guide but here's what you need to do:

1. Use powershell script to install nuget:

2. In Unity Directory create following:
   Plugins>Windows>X86_x64

3. Paste all the TorchSharp dlls in there (I dont remember how to get them, just copied them from .NET 8.0 project I had around)
   

4. Make sure that all the .dll settings in the inspector are like this:

Great Thanks. It works.
Though it works, but I still have question about libtorchsharp, why after appling CPU config to x64, and it became back to "Any CPU"?

The error you're getting should be solved by #1461
