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).
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...

Re: Lc0 ... the GOOD and the BAD

Of course I don't have A0, but I do have 100 games it played against SF. So I went through some games with Lc0 and it was remarkable that almost every move was a match with Lc0. The only moves that did not match were tactical shots that Lc0 could not see. So you could say that once Lc0 sorts out th...

Re: Dramatic drop in performance with LC0 after updating Cuda drivers

Actually I did download what was the latest Cuda drivers from Nvidia … I think it was version 10. But somehow installing those drivers installed like 8 different subsets of drivers, including Physix (or something like that) and a bunch of other stuff that I have no clue what they were. Most likely ...
