We have an official version of the LcZero engine. We will start the first tests today!
Lc0 v.0.32.1 what news?
In this version:
Strict timing is applied only if isready was seen, for more accurate timing.
Better onnx-trt installation script that will download everything needed without user intervention.
Improved transposition table memory use calculation for the memory limit.
A small speed improvement for dag-preview search.
Some important bug fixes:
Two en-passant related bugs
Guard against infinite fp16 input in cuda Softmax kernel.
Changed the way the WDL draw value is calculated in some backends to avoid underflows.
The onnx backend WDL Softmax calculation was moved to the cpu for improved accuracy (like other backends already do).
Correct onnx moves left head final activation.
Fix for cudnn attention policy with convolutional nets.
A few more minor fixes.
Assorted build system improvements.
