Re: Lc0 51010

NN 51010 has had 559441 games. The NN size is smaller (10x128) than the A0 one and 41xxx NNs (20x256), but the training param is visits=10000 (visits=800 for 41xxx). I'll let others say what 2080 time that works out to. I will try to estimate (writing on the phone, I am on a vacation :) ). About 0....

Re: Lc0 51010

One question: does anyone know roughly how many 2080s would be needed to duplicate the training that this 51xxx series has averaged so far? It doesn't mean much to say that it has trained for two days without stating what the average resources used for the training were. I imagine that they were ju...

Re: Lc0 51010

Stockfish was not as impressed as Fruit. Lc0 51012 vs Stockfish Results.jpg Well I don't expect a 3250 engine to score much against SF on a powerful computer. The point is that if it is 3250 level with a self-play rating under 1500, what should it be with a 3000+ self-play rating in a few weeks? Sa...

That is inaccurate. It is averaging around 800 visits per move too.

Re: Help with installing Leela (2 Geforce RTX 2080 TI graphics cards)

Hello. I am wondering if I could get some further advice from the experts here. I have just installed 2 Geforce RTX 2080 Ti graphics cards on my workstation, which has two Xeon processors and a total of 24 cores. As far as I can tell, the graphics cards, which were installed by a friend who is an e...

Re: Leela on two RTX cards, technical question

Hi there i have installed two RTX cards for Leela. Are there parameters to bring out the best performance for such setup? Right now I get 60.000 nps - 65.000 nps in console mode after go depth 5000000 But ist different when using leela in a game. Pretty soon the GPU load is going down to 70% - 80% ...

Re: Chess Fighter Neural Net

I have had a similar frustrating experience with reinforcement learning before i deemed it too big a project for one man. What input planes do you use besides piece placement? I use attack tables and piece counts as additional inputs and they seem to help accelerate learning. Do you use replay buff...

Re: Is AlphaZero-LC0 (Leela0) A chess Engine?

...Deep Mind's claims also hinge on the conditions, not least of which is that they ran AlphaZero at roughly a 900 to 1 NPS handicap. Not a fair comparison of the engines at all. I wonder how it would have gone if the hardware were more comparable. When I use dkappe’s Leela ratio to equalize GPU to...

Re: Is AlphaZero-LC0 (Leela0) A chess Engine?

I don't like Leela ratio. My suggestions: 1. CPU and GPU same price 2. Best possible CPU/GPU you can get. 3. Max 1000 € readybuilt gaming PC. Fair or not !? Not sure what this changes, except the strange 3) you placed. Also, prices will vary quite a bit from continent to continent. So I looked up t...
