This is a basic tool/aid for training and creating stockfish-nnue eval networks (nn.bin) using nodchip's stockfish-nnue software: https://github.com/nodchip/Stockfish/releases or https://github.com/FireFather/Stockfish-nnue
It's a basic GUI to keep track of settings, paths, UCI options, command line parameters, etc. It will also launch the various binaries needed for all 3 phases: gen training data, gen validation data, and learning (training).
It's a native 64-bit Windows application, with no external dependencies, and should run on most systems.
