I wish to train an NNUE for Stockfish using my own positions and evaluations, please explain how I would do this

First convert your data into a compatible format (binpack), then use https://github.com/official-stockfish/nnue-pytorch to train your network. Please join the Stockfish discord if you have any further questions.

Here is a project aiming to make the training reproducible, which you might also find handy: https://github.com/vondele/nettest
