Installation Issues?

error: failed to run custom build command for `torch-sys v0.14.0`
note: To improve backtraces for build dependencies, set the CARGO_PROFILE_DEV_BUILD_OVERRIDE_DEBUG=true environment variable to enable debug information generation.

Caused by:
  process didn't exit successfully: `C:\Users\PCName\Desktop\VS-Code\Otis\target\debug\build\torch-sys-5fcd1056113e7b81\build-script-build` (exit code: 1)

  --- stderr
  Error: 
  Cannot find a libtorch install, you can either:
  - Install libtorch manually and set the LIBTORCH environment variable to appropriate path.
  - Use a system wide install in /usr/lib/libtorch.so.
  - Use a Python environment with PyTorch installed by setting LIBTORCH_USE_PYTORCH=1

I checked my $env paths (on Windows) and found that everything should be setup properly:

``
LIBTORCH_USE_PYTORCH           1
LIBTORCH                       C:\Users\PCName\Desktop\VS-Code\Otis\libtorch
``

My Libtorch (that I installed) is a Stable 2.1.0, Windows, LibTorch, C++/Java and for CPU

I did run the 2nd powershell command $Env:Path += ";C:\Users\PCNAME\Desktop\VS-Code\Otis\libtorch\bin" however I cannot seem to find it when running Get-ChildItem env:

I tried to use PyTorch because I already have the package (and knows it works because I already ran a model with it)

So I am rather confused on what I should do? I read the readme and couldn't find any videos on how to install it step-by-step.

Update; Managed to get it running.
