Torchsharp in unity

[newzaungo3]

Hello I'm newbie from using torchsharp in unity.

First of all, I try to install torchsharp via nuget in unity. It's normal work on installation. However, when I run a simple code, I face a problem like this

NotSupportedException: The libtorch-cpu-win-x64 package version 2.1.0.1 is not restored on this system. If using F# Interactive or .NET Interactive you may need to add a reference to this package, e.g. 
    #r "nuget: libtorch-cpu-win-x64, 2.1.0.1". Trace from LoadNativeBackend:

TorchSharp: LoadNativeBackend: Initialising native backend, useCudaBackend = False

Step 1 - First try regular load of native libtorch binaries.

    Trying to load native component torch_cpu relative to D:\work\.....\Assets\Packages\torchsharp.0.101.6\lib\netstandard2.0\TorchSharp.dll
    Failed to load native component torch_cpu relative to D:\work\.....\Assets\Packages\torchsharp.0.101.6\lib\netstandard2.0\TorchSharp.dll
    Trying to load native component LibTorchSharp relative to D:\work\.....\Assets\Packages\torchsharp.0.101.6\lib\netstandard2.0\TorchSharp.dll
    Failed to load native component LibTorchSharp relative to D:\work\.....\Assets\Packages\torchsharp.0.101.6\lib\netstandard2.0\TorchSharp.dll
    Result from regular native load of LibTorchSharp is False

Step 3 - Alternative load from consolidated directory of native binaries from nuget packages

    torchsharpLoc = D:\work\.....\Assets\Packages\torchsharp.0.101.6\lib\netstandard2.0
    packagesDir = D:\work\.....\Assets
    torchsharpHome = D:\work\.....\Assets\Packages\torchsharp.0.101.6
    Trying dynamic load for .NET/F# Interactive by consolidating native libtorch-cpu-win-x64-* binaries to D:\work\.....\Assets\Packages\torchsharp.0.101.6\lib\netstandard2.0\cpu...
    Consolidating native binaries, packagesDir=D:\work\.....\Assets, packagePattern=libtorch-cpu-win-x64, packageVersion=2.1.0.1 to target=D:\work\.....\Assets\Packages\torchsharp.0.101.6\lib\netstandard2.0\cpu...

I try to solve this problem all day like install libtorch-cpu-win-x64, using

TorchSharp.torch.InitializeDeviceType(TorchSharp.DeviceType.CUDA); 

but still can't figure it out. Can someone help me.

My setup
Torchsharp-cuda-windows version 0.101.6
libtorch-cpu 2.1.0.1
libtorch-cpu-win-x64 2.1.0.1
