`AccessViolationException` in `TorchTensor.Dispose`

See original GitHub issue

By following memory guide, I added GC.Collect into my code after every epoch. The first such call after an epoch of training crashes with

Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at TorchSharp.Tensor.TorchTensor.THSTensor_dispose(IntPtr) at TorchSharp.Tensor.TorchTensor.THSTensor_dispose(IntPtr) at TorchSharp.Tensor.TorchTensor.Dispose(Boolean) at TorchSharp.Tensor.TorchTensor.Finalize()

Repro steps (requires .NET 3.1 Core and C# 9, Windows only):

Clone https://github.com/losttech/Torch.Siren.git
Checkout TorchSharpBugs/315
go to app subfolder
dotnet run path_to_image.jpg

When done from command line, simply crashes with Fatal error. Internal CLR error. (0x80131506) When run from Visual Studio (use Siren.sln at the root), also displayed the stack trace.

Without the call to GC.Collect memory is leaking fast.
