Subject: Update default net to nn-c38c3d8d3920.nnue
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=e699fee513ce26b3794ac43d08826c89106e10ea

Update default net to nn-c38c3d8d3920.nnue

This was a later epoch from the same experiment that led to the
previous master net. After training, it was prepared the same way:

1. greedy permuting L1 weights with https://github.com/official-stockfish/Stockfish/pull/4620
2. leb128 compression with https://github.com/glinscott/nnue-pytorch/pull/251
3. greedy 2- and 3- cycle permuting with https://github.com/official-stockfish/Stockfish/pull/4640

Local elo at 25k nodes per move (vs. L1-1536 nn-fdc1d0fe6455.nnue):
nn-epoch739.nnue : 20.2 +/- 1.7
