Lc0 v0.18.0 has been released.

v0.18.0 is out of "release candidate" status, and now is fully released!

Can be downloaded here.

It has no changes relative to RC2. For the list of differences relative to v0.17, see posts for v0.18.0-rc1 and v0.18.0-rc2.

For people contributing training games, there's no need to rush to upgrade, it's fine to use v0.17.


There is a small known issue with time management. The version v0.18.0 times out sometimes when all of the following is true:
  • Ponder is ON
  • Time is added every X moves (e.g. every 40)
  • There is per move increment
Most probably there will be v0.18.1 soon where this issue is fixed.

  1. Does the time-out happens even when Leela has a winning game?

  2. Leela seems to play a very attacking style of play. I was wondering if it was because her training goal is to win. Would it be different if her primary goal was "not to lose?" Just curious.

    2. The goal of chess is to checkmate the king. I believe leela is in a phase where playing positions that can increase chances of checkmating the king is key. This is something about king safety that classical engines have difficulty addressing in general simply because of how complex these situation are. However leela does have very good positional evaluations regardless of what seems to be an attacking style of play.
