How to install a BOT on Lichess?

Do I need to download weights? And what weights should I choose?

Leela Chess Zero uses weights although I don't know the details.

I'm using multi-variant Stockfish which does not require neural network weights.

If you use Leela, yes of course, you need the weights. Always use the latest weights (that with the highest ID).

http://lczero.org/networks

you will also need to unzip the downloaded weights. Then rename it to eg. "weights.txt" and call the engine like "lczero.exe -w weights.txt" - assuming that the weights.txt is in the same dir of the lczero.exe

How many bots are on lichess now?

@nh78, thank you, now I'm trying "python main.py", but getting this: https://pastebin.com/TJvaw7tD
And it doesn't play...
Unzipped, trying now.

@nh78, now getting this:

And after I changed it to
engine: "lczero.exe -w weights.txt"
weights: "weights.txt"
It also doesn't work...
Before it was this:
engine: "lczero"
weights: "latest.txt"

The error message says at the end:
yaml.scanner.ScannerError: could not find expected ':' in line 8, column 1

this indicates there is a ':' missing in your config.yml. Possibly in the line starting with 'threads'?

(Python error messages can actually be helpful)

could you also post the config.yml to pastebin ?

but dont post the auth token!!
