You can use a text editor to edit the file "lizzie.properties". There's "max-game-thinking-time-seconds" for you.

Anyone know how to run LZ on sabaki?What's this mistake?

It says "Welcome to the world of computer program calls and arguments. Welcome to the real world, it's not all apples!"

Learn from my Sabaki setting. "bestnet" is my weights file. It resides in the same folder as leelaz.exe.

It seems that you have not unzipped your weights file. The download is *.gz and you have to extract it before LZ can use it.

Lizzie hardcodes the "./leelaz" command. I wanted to run an SSH command though to connect remotely to a more powerful machine, using my notebook merely as a terminal. So I made a little patch to allow arbitrary commands in lizzie.properties file:

lizzie-master\src\main\java\wagner\stephanie\lizzie\analysis\Leelaz.java:
Replace

Code:

        commands.add("./leelaz"); // windows, linux, mac all understand this
        commands.add("-g");
        commands.add("-t");
        commands.add(""+config.getInt("threads"));
        commands.add("-w");
        commands.add(config.getString("weights"));
        commands.add("-b");
        commands.add("0");

by

Code:

      // C. Blue - Replacing hardcoded leelaz binary with arbitrary command (to enable easy remote connection via SSH)
      //  Additional unrelated notes:
      //   max-analyze-time-minutes is a timeout after which pondering is automatically turned off (presumably to freeze the % numbers)
      //   max-game-thinking-time-seconds has no effect.
      //   The default code (see further below) added "-b 0" aka 0s lag buffer.      
      if (!config.getString("command").isEmpty()) {
         String[] comms = config.getString("command").split(" ");
         for (int i = 0; i < comms.length; i++)
            commands.add(comms[i]);
      } else {
         commands.add("./leelaz"); // windows, linux, mac all understand this
         commands.add("-g");
         commands.add("-t");
         commands.add(""+config.getInt("threads"));
         commands.add("-w");
         commands.add(config.getString("weights"));
         commands.add("-b");
         commands.add("0"); //(C. Blue: hardcoded lagbuffer? hm)
      }

Then add a "command" key to lizzie.properties under "leelaz" so it looks like this for example:

Code:

{
  "leelaz": {
   "command": "C:\\Progra~1\\OpenSSH\\bin\\ssh.exe -p someport 'somename'@somehost",

Again, if "command" is non-empty, all the other parameters will be skipped. If it is empty, like this:

Code:

"command": "",

then all the other keys are used instead, just as before.
I used Maven to build lizzie, as recommended on https://github.com/featurecat/lizzie .

Alternatively, instead of patching the lizzie code you could of course also just create a custom replacement [script] for leelaz, as described by 'dwt' here for example: https://github.com/featurecat/lizzie/issues/92

PS: In case you were wondering why my ssh command doesn't contain an actual leelaz-call, that's just because I predefined leelaz (plus its parameters) in the server's authorized_keys file as the default command to run for any ssh connection (along with the usual other safety measures

).

You might consider submitting this as a pull request. I know that featurecat was planning on putting this feature in but I don't know if it's been implemented in the official copy yet. (I just use the "replace leelaz by a shell script" solution.)

What is the meaning of the numbers in the circles, and the colors of the circles? A link would be fine.

Javaness2 · **#50**

This should be in the GitHub wiki

Sorry to be dense, but where is that? I tried clicking on all the github links here in the thread and didn't see a wiki....

What I really want to know, is how to interpret the information that lizzie shows.

The top number is Leela Zero's evaluation of the winning percentage. By default this is from the point of view of the side to play (e.g., if it says 57.2, then the player whose turn it is has a 57.2% chance to win if they play at that point).

The bottom number is the number of "visits", the times Leela Zero has considered the position that would result by playing on that point. It goes up as Leela Zero looks at more variations starting with that move. As you might expect, it will spend most of its time analyzing the most promising moves.

The color is a visualization of the bottom number. The point with the most visits is bright green and surrounded with a red circle; this is the move that Leela Zero would make if you asked it to choose a move right now. As points get less visits, the color becomes more red and more translucent.

I just copied the 0.4 version. When I run it from the windows command prompt I got this error message:

I have only used Java 8 for this in the past, but I just tried Java 10 and it gets a bit further if you do this:

java -Dsun.java2d.d3d=false -jar Lizzie.jar

But there are still some other errors logged to the console, so I am not certain it will work properly. It is likely the author never tested it with Java 10.

splee99 · **#57**

Interesting. It seems to be working now with that special command.

Uberdude · **#58**

Version 0.5 is released:

https://github.com/featurecat/lizzie/releases/tag/0.5

Gomoto · **#59**

And 0.5 is also friendly to Elf.

Uberdude · **#60**

Great point Gomoto, I'm looking forward to finally receiving some Elvish wisdom!
