New version of Leela

Post by corres »

You can download from lczero.org the version 0.26.2 of Leela. Leela developer made lot of modification on version 0.26.1 but they did not change CUDA version. It is pity, because using CUDA 11 (instead of 10.2)
and using cudnn 7.6.4 (nstead of 7.4.2) Leela could get about 30 % speed enhance in the case of SV-384x30 (big) nets. So Leela could gain ~ 10-20 Elo.

v0.26.2 = v0.26.2-rc1

* Repetitions in the search tree are marked as draws, to explore more promising lines. Enabled by default (except in selfplay mode) use --two-fold-draws=false to disable.
* Syzygy tablebase files can now be used in selfplay. Still need to add adjudication support before we can consider using this for training.
* Default net updated to 703810.
* Fix for book with CR/LF line endings.
* Updated Eigen wrap to use new download link.
