NotSupportedException: This application or script uses TorchSharp but doesn't contain a reference to libtorch-cpu-win-x64, Version=2.5.1.0.
Consider referencing one of the combination packages TorchSharp-cpu, TorchSharp-cuda-linux, TorchSharp-cuda-windows or call System.Runtime.InteropServices.NativeLibrary.Load(path-to-LibTorchSharp.dll) explicitly for a Python install of pytorch. See https://github.com/dotnet/TorchSharp/issues/169.".
For CUDA, you may need to call 'TorchSharp.torch.InitializeDeviceType(TorchSharp.DeviceType.CUDA)' before any use of TorchSharp CUDA packages from scripts or notebooks.
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 C:\Users\Danilkin\Desktop\kursach\jest\bin\Debug\TorchSharp.dll
Failed to load native component torch_cpu relative to C:\Users\Danilkin\Desktop\kursach\jest\bin\Debug\TorchSharp.dll

Failed to load native component LibTorchSharp relative to C:\Users\Danilkin\Desktop\kursach\jest\bin\Debug\TorchSharp.dll
Result from regular native load of LibTorchSharp is False
Step 3 - Alternative load from consolidated directory of native binaries from nuget packages

Giving up, TorchSharp.dll does not appear to have been loaded from package directories
