winrate and komi

[palusijf]

HI,

I don’t understand why the win rate is still the same whatever the value of the Komi.
For the first move with LZ network (#225) :

• with Komi = 7 .5 : WR = 43.6
• with Komi = 0 : WR = 43.6

Winrate is from output of neural network's value head.
But neural network doesn't have a input for komi.
Therefore, regardless of GTP komi settings, winrate is calculated based on komi of 7.5 points.
Because weights are trained from komi 7.5 self-play games and value head output is estimation of its game result.

Simply speaking, you can't change komi from 7.5 points.

Ok, thanks for the answer.
