Update main network to nn-af1339a6dea3.nnue This network is trained by adding the following binpacks, relabeled by @vondele and totaling 74B positions, to the distillation fine-tuning stage: ``` - vondele/from_kaggle_1_relabel/leela96-filt-v2.min.split_0.relabel-BT4-tf13tune.binpack - vondele/from_kaggle_1_relabel/leela96-filt-v2.min.split_1.relabel-BT4-tf13tune.binpack - vondele/from_kaggle_1_relabel/leela96-filt-v2.min.split_2.relabel-BT4-tf13tune.binpack - vondele/from_kaggle_1_relabel/leela96-filt-v2.min.split_3.relabel-BT4-tf13tune.binpack - vondele/from_kaggle_1_relabel/leela96-filt-v2.min.split_4.relabel-BT4-tf13tune.binpack - vondele/from_kaggle_2_relabel/T60T70wIsRightFarseerT60T74T75T76.split_0.relabel-BT4-tf13tune.binpack - vondele/from_kaggle_2_relabel/T60T70wIsRightFarseerT60T74T75T76.split_1.relabel-BT4-tf13tune.binpack - vondele/from_kaggle_2_relabel/T60T70wIsRightFarseerT60T74T75T76.split_2.relabel-BT4-tf13tune.binpack - vondele/from_kaggle_2_relabel/T60T70wIsRightFarseerT60T74T75T76.split_3.relabel-BT4-tf13tune.binpack - vondele/from_kaggle_2_relabel/T60T70wIsRightFarseerT60T74T75T76.split_4.relabel-BT4-tf13tune.binpack ``` The relabeling effort has been completed during the testing of this patch, and a full training run is on the way.
