Finally official Lc0 v0.31.0-rc1

Post by Jouni »

here https://github.com/LeelaChessZero/lc0/r ... 0.31.0-rc1. For Apple users: Multihead arch metal added. But I think biggest problem for Lc0 that there is no official net! So we will NEVER know how strong it really is.

But what we DO KNOW, is that LC0 is faster and better on most modern cheap nvidia laptops, than on an úberpriced Apple computer :-)

It runs fine and it's strong enough.

I agree. Although the standard Leela site continues to declare that the latest "stable" iteration is 30.0, I suspect that the Leela team just hasn't updated all their websites.

I'm running Leela 31.0 now with the BT4 net, and everything seems fine and "stable" to me.

Yes and because of úberpriced Apple computer, everybody is buying those :lol: :lol: :lol:
Don't forget to mention that only some LC0 developers are tuning LC0 from the beginning for Nvidia GPUs, because they have only these GPUs and no AMD or Apple GPUs. So it's completely basic that LC0 is faster on Nvidia GPUs after all these years.
They could easily use some AMD GPUs and improve the speed of LC0 on those GPUs or on Intel GPUs.
The developers mentions years ago that they could easily improve the speed of LC0 by a factor of 5x but they are to much Nvidia guys.
= It's a developers / money problem and not an Apple, AMD or Intel problem.

They have problems to compile v0.31.0-rc1 on Apple devices https://github.com/LeelaChessZero/lc0/r ... 0.31.0-rc1

Official releases of Lc0 in the past always came with a bundled net that was by definition the official net. Do they not do that now ?

This is my quick verification test of 120 positions. I have much larger tests of similar quality, but nobody will have the patience to run them.

I was unable to get this network to function:
03/26/2024 04:47 PM 190,937,780 BT3-768x15x24h-swa-2790000.pb.gz
which is (according to my understanding) the one used by TCEC.
There is no screen activity nor any CPU effort by Lc0 when I use that network.
No idea why.

A suggestion for Lc0 team:
Scan the hardware and use what is learned to set the UCI parameters automatically. A thousand users will bless you.
Me at the top of the list.
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.

Here are the results for the new Lc0 (which was notoriously poor at tactics):

Many thanks.

So, what is the comparison to the old Lc0? In your own words.

What network should I use on an i7, 13 gen, desktop with 32 GB RAM?
