Now, should I reinstall Pytorch from the link on its official website and run programs from Anaconda Prompt? Or do I need to do something else before reinstalling pytorch?


The point is that the version you would install normally (e.g. a precompiled binary) lacks the support for such an old GPU, so to specifically make use of the GT730 you need to build the program from scratch with that support baked in; at no point would you be downloading a full version to install.
To answer some of the other points: you would be best served with the stable version, as you don’t want an unstable build with still-in-testing features you won’t be using; Visual Studio is necessary to provide a compilation environment on windows. If you want your programs to run using GPU acceleration (yes), then you need Nsight installed as it suggests.
