In case you missed it. Quoting the author (not me)
Nibbler is intended to be somewhat like Lizzie, but for Leela Chess Zero. In other words, it is a GUI that runs a single engine (in our case, Lc0) constantly, displaying opinions about the current position.
Recently version 0.5.3 of Nibbler, a Leela Chess Zero (Lc0) interface, was released at https://github.com/fohristiwhirl/nibbler

Notice that a config.json file has to be created to reflect the path of your Lc0 locations. An example file is provided.

My favorite feature is playing versus a network set to search nodes = 2. It's awesome, how strong these networks are without any search.

Great GUI!
Making a gui for chess engine is no small feat.
As far nodes / second. NN engines are well optimized and really fast. Just how they calculate matrices is not counted in nodes / second.

Very interesting! Will have a go installing it over the weekend.

In the meantime if anyone is interested, can you have a go at running the start position
but with bishops and knights swapped (for white and black) for a few minutes and posting
an image like the previous post? I've run games with this in the past, some engines go
for the c3 f3 c6 f6 moves. Some like e4 and d4 more. How about Leela?

I'll also mention in the above image, you cannot distinguish between an eval for a3 and Na3.
Maybe two or more evals on the same square?

Veiwing the centipawn evaluations with the color coded moves on board are a nice touch with moving thru a game. Allows you more time viewing the board rather than the analysis window. Plus I am glad that it defaults to lc0.config once paths are set in config.json

Does anyone know here I can download the "Alexei" weights file? :roll: :lol: The JH.T8.610 weights net is taking to long.

Has anybody tried out Nibbler GUI with other UCI-compatible engines e.g SF, Fire? cf. https://github.com/fohristiwhirl/nibbler/issues/25

Why should we? It is designed for Leela and he already answered you at github...
