Need Lc0 help

Post by Dann Corbit »

My best card is a 1080 Ti and the machine it sits in needs a new power supply.
Stockfish seems powerless in these positions. 2 hours with 64 cores does not help.
I can tell by examination of the statistics that the SF answers are not correct.
Does someone have a high end GPU setup and the time to pound these positions for a while?
(BTW, these are from Ed's two move file.)

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I should mention that they are ordered from worst to best.
IOW, SF eval is off by at least a pawn after a deep search for the top one.
SF eval is off by a quarter pawn at the bottom of the list.
So the ones I care most about are at the top.

I can help. For how long do you want to run each position ?

A peculiarity of lc0 is that it needs history to analyze a position. I think the default behaviour is the worst so I switched
to filling history with current position.

Code: Select all

$ ./lc0 -t 2 --backend=cudnn-fp16 --history-fill=always --verbose-move-stats --weights=./ID-31230.gz

Also do you know how you set up a uci engine to analyze a list of epd positions ?

Let's start with two positions for as long as you can stand it (but two hours should be PLENTY).
The reason is I do not know for sure if LC0 can solve them either.
I know the right answers by statistics of actual game outcomes.

To run a list of EPD positions on windows or Unix try Arena.

Two hours is probably overkill. The given answer is correct.
Stockfish, after 2 hours with 64 physical cores and 64 GB of RAM emits:
Nf6
losing a full pawn in strength
And e5 is the correct move.

Stockfish seems powerless in these positions. 2 hours with 64 cores does not help.
I can tell by examination of the statistics that the SF answers are not correct.
Does someone have a high end GPU setup and the time to pound these positions for a while?
(BTW, these are from Ed's two move file.)

Can you elaborate on how you are determining "correct" here? Why is e5 correct and not Nf6?

Using Arena to analyzea list of positions:
1. Use menu item Engines/Automatic Analysis
2. Make sure logging is turned on.
I have a program that will consume the EPD input file and the Arena analysis output to create decorated EPD records

I am using statistical results from actual games to compute the "real" centipawn evaluation.
When you only have a hundred games, there is no way to know if the computer or the statistics are correct.
But when you have many thousands of games (filtered to remove weak entrants) then the game outcomes are to be trusted.
The move e5 triumphs. Nf6 is drawish.

The move e5 triumphs. Nf6 is drawish. You can get hundreds of millions if games from Lichess, and the opponents have tried everything.
Of course, Lichess is mostly bad data, so it needs filtering.
Add in the OM database, CCRL, CEGT, TCEC and a few other reliable sources and you can get really good statistical insights,

Ok two hours it is.
But note that MCTS engines consume lots of memory for storing their trees so it might not be possible to run for that long.
I have 256gb ram though on the cpus so it may go for 2 hours...
