Stockfish NN release (NNUE)

[cucumber]

Good news! SF NNUE is now being updated to SF dev! Also you can compile it now with msys2/mingw instead of Visual Studio. It still throws some warnings but the binaries work. For the blas binaries obviously the libopenblas dep has to be installed as well.

Also a nice bit of information from the computer shogi experts is that 1 million fens for validation is enough.

I still can't get binaries to work with mingw. Norman's code seems promising, though. Now to setup Visual Studio on my VM...

FWIW, I've added a few includes and changed some gcc flags and it builds and runs under Linux here: https://github.com/manyoso/Stockfish

Check the readme for instructions... and if someone has a more recent net I'd appreciate it as the one I'm using is giving garbage output.

That runs for me! Thanks.

It now gives reasonable output when you don't set the SkipLoadingEval which I mistakenly assumed you had to set to skip regular SF eval

Ok, now optimization is on and figured out the threading issue and I now see 3.2Mnps with 12 threads running under native linux.

I posted some changes to https://github.com/FireFather/Stockfish-nnue

1) UCI changed (is_ready() moved to UCI:loop)
2) consequently, UCI works normally, and nn.bin loads immediately on program start
3) comments translated to English

Visual Studio project files are included.
Hope this may help, or be of some use.

Thanks much to Hisayori Noda for his efforts and awesome code!

Your x64 binary does not work in cutechess-cli. In console-mode it runs on my Haswell-CPU. Strange.

One thing I've noticed is that all SF-NNUE versions so far don't seem to recognize a modified contempt setting, especially for White, during games. The engine appears to ignore the setting.

Would anyone be willing to test this net? https://cdn.discordapp.com/attachments/ ... 4211/nn.7z

I've trained it off of fishtest games. I expect it to play endgames poorly (especially without TBs) since those don't appear much in training games. My code to go from PGNs to SF-NNUE training data could be broken, too, but I don't have a clue.

If you test it and would be comfortable sharing PGNs, that'd be really nice, too.

You will need 7-zip, WinRAR, or another archive utility to extract the file.

What binary to use?
Looks like a Crepe net.

You need to use the halfkp binary.
edit: I've received word that it's a pretty broken network. That's unfortunate
