Quick correction: --noise does not cause randomness in its play, it just introduce some randomness in the search, but the moves introduced are evaluated and discarded if they are found to be not good enough.
The randomness in its play that you see in self-play training games is caused by another thing, temperature=1

I just had an interesting game against slow mode (which is fixed to 2k playouts per move now).

Is there a way to install LCZ on the PC and set the time controls etc myself? I'll bet it gets a lot stronger with more time.
Also does a faster graphics card = better chess? Does it all more rollouts per second?

Thanks.
I did all that and it said at the end to type a line into my GUI - which GUI will work?

I tried it on Arena and got an error message:
libopenblas.dll missing
any ideas?

Well then you did
not follow the steps written there.
Otherwise you would have libopenblas.dll already.
Obviously you omitted the step with the leela go version.
This download contains the missing files needed also for leela chess.
Code: Select all
Download LZGo:
https://github.com/gcp/leela-zero/releases/download/v0.12/leela-zero-0.12-win64.zip
Unzip LZGo, and copy LZChess client.exe and lczero.exe into the same folder.

OK, I've followed all steps properly and the command line seems to work now, it shows how many GFLOPS I'm running etc.
After it has completed the command line procedure, how do you actually get the engine to play?
I loaded lczero as an Arena engine (was that the right thing to do?) but it doesn't respond when I play a move.
I feel so close...thanks for your help.

Try starting the engine from the command line. If that's successful, it will show an output like
Using 1 thread(s).
Generated 1924 moves
Detecting residual layers...v1...64 channels...6 blocks.
At this point, enter "go" to prompt it to play a move. If that works, the rest is a matter of configuring the command line options in Arena properly, I saw some answers to that in this thread (or the predecessor thread anyway)

Have you downloaded a network file
and extracted it?
(the network file is a compressed file)
Have you added the commands themselves or the batch file in the commandline options for Arena (where ever that is - because I don't use it)?
Also note that LCZero speaks uci.
