Embed default net, and simplify using non-default nets covers the most important cases from the user perspective: It embeds the default net in the binary, so a download of that binary will result in a working engine with the default net. The engine will be functional in the default mode without any additional user action. It allows non-default nets to be used, which will be looked for in up to three directories (working directory, location of the binary, and optionally a specific default directory). This mechanism is also kept for those developers that use MSVC, the one compiler that doesn't have an easy mechanism for embedding data. It is possible to disable embedding, and instead specify a specific directory, e.g. linux distros might want to use CXXFLAGS="-DNNUE_EMBEDDING_OFF -DDEFAULT_NNUE_DIRECTORY=/usr/share/games/stockfish/" make -j ARCH=x86-64 profile-build passed STC non-regression: https://tests.stockfishchess.org/tests/view/5f4a581c150f0aef5f8ae03a LLR: 2.95 (-2.94,2.94) {-1.25,-0.25} Total: 66928 W: 7202 L: 7147 D: 52579 Ptnml(0-2): 291, 5309, 22211, 5360, 293 closes https://github.com/official-stockfish/Stockfish/pull/3070 fixes https://github.com/official-stockfish/Stockfish/issues/3030 No functional change.
