Make net nn-190f102a22c3.nnue the default net. Trained with the pytorch trainer: python i:/bin/all.binpack i:/bin/all.binpack --gpus 1 --threads 4 --num-workers 30 --batch-size 16384 --progress_bar_refresh_rate 300 --smart-fen-skipping --random-fen-skipping 3 --features=HalfKAv2^ --lambda=1.0 --max_epochs=440 --seed %random%%random% --default_root_dir exp/run_17 --resume-from-model ./pt/ This run is thus started from the previous master net. all.binpack equaled 4 parts Wrong_NNUE_2.binpack plus two parts of Training_Data.binpack Each set was concatenated together - making one large Wrong_NNUE 2 binpack and one large Training so the were approximately equal in size. They were then interleaved together. The idea was to give Wrong_NNUE.binpack closer to equal weighting with the Training_Data binpack passed LTC LLR: 2.93 (-2.94,2.94) <0.50,3.50> Total: 32184 W: 1100 L: 970 D: 30114 Ptnml(0-2): 10, 878, 14193, 994, 17 passed STC LLR: 2.93 (-2.94,2.94) <-0.50,2.50> Total: 11360 W: 1056 L: 906 D: 9398 Ptnml(0-2): 25, 735, 4026, 853, 41 closes Bench: 4631244
