lczero gets about 30 per day. do you know how many leela zero gets a day.?
10600 Elo gained in about 160 days would be about 66.

But I don't think such a comparison makes much sense.
and what about elo gains against other go programs?

There aren't enough to be useful as a baseline, Leela Zero is far stronger than anything else that is publicly available.

They're saved in the leelaz_opencl_tuning file and remembered.
All for naught, it is clear to me that my GPU is not being used.
The end-around I found on the net failed, and my back-off to an older driver is hung for an hour now.

I guess it is time to buy a nice Nvidia card.
Some numbers as references for the speed :
On my old GTX 750 Ti : 0.7 Kn/s (700 n/s)
On a GTX 1080 Ti : around 2.5 Kn/s
On the TCEC server (43 cores @2.8 GHz) : 5 Kn/s

so leela zero is stronger than Finearts ?

https://qz.com/936654/googles-alpha-go- ... r-fineart/

FineArts first encountered Ke on foxwq.com during November, taking a win and a loss. But after an update in February, the algorithm has since won 10 straight games (link in Chinese) against the world’s No. 1 player.

As Tencent’s tech blog explains (link in Chinese), FineArts works in a similar way to AlphaGo. Both AIs comprise two computer systems modeled on the human brain, which can be trained on large data sets. One part of the system, the “policy network,” predicts which of the possible moves are the likeliest to be played. The other, the “value network,” then evaluates which of those is likeliest to win.

I said "publicly available".

We have no way to test against Fineart. Of course, they are free to setup Leela Zero in a handicapped manner in a private match and claim superiority. This is an approach that has been proven successful in the past and is hence likely to be tried again.

My CPU training is working. Thought I'd try the GPU (it's not up to much but I could upgrade it) and get this:-

Any ideas about the last line error; it's something to do with the output chunker whatever that is...?

It was a clean install on Windows via the zip from the Leela website, then running:-

.\client.exe -debug

Are you able to update your video driver? No idea if that's the cause, but this is extremely old.

I'll give it a whirl.

If I was to buy a video card just to train Leela, what would be recommend? I can get it through work; so may as well.
