Automatically converts all .ckpt found under run96 to .nnue and runs games to find the best net. Games are played using c-chess-cli and nets are ranked using ordo. This script runs in a loop, and will monitor the directory for new checkpoints. Can be run in parallel with the training...
NNUE are efficiently updateable neural networks, which were first applied to shogi, then later also applied to official Stockfish. From there it made its way into Fairy-Stockfish. Several generalizations have been applied to the architecture of the neural network so that it can be used for differ...
If "Use NNUE" is set to "true", the network parameters must be available to load from file, if they are not embedded in the binary. make时会调用wget下载。 The NNUE evaluation was first introduced in shogi, and ported to Stockfish afterward. It can be evaluated efficiently on CPUs, and ...
the TB, a sequence of moves that preserves the game outcome to checkmate. *NUMA performance optimization* For high-end computers with multiple CPUs (typically a dual-socket architecture with 100+ cores), this release automatically improves performance with a `NumaPolicy` setting that optimizes non...

- Dual NNUE: For the first time, Stockfish includes a secondary neural network, used to quickly evaluate positions that are easily decided. UCI Options removed: Use NNUE and UCI_AnalyseMode have been removed as they no longer had any effect. SlowMover has also been removed in favor of Move...
Let's continue using the architecture from the forward pass implementation.Model specificationPytorch has built-in types for linear layers, so defining the model is pretty simple.class NNUE(nn.Module): def __init__(self): super(NNUE, self).__init__() self.ft = nn.Linear(NUM_FEATURES, ...
