Where to download current TCEC version of LC0 ?

Post by gordonr »

Hi

I see that TCEC is currently using 0.30-dag-8092b376-BT2-3650000 version of LC0. Is this publicly available? If so, where to download exe and net?

thanks
Gordon

Apologies for answering my own question but after waiting a delay setting up a Twitch account, I was able to ask on the TCEC chat too and got the following...

Engine exe:
https://ci.appveyor.com/project/uwuplan ... s/46546368

Network:

Everything is correct except for the Lco version - it is 8092b376 not d3c16986

Ok, thanks. I'm presuming it's a very close version.

ah, my bad. the version I had sent in chat is slightly more recent, should just contain a few recent additions to contempt. the version actually being used at TCEC is https://github.com/borg323/lc0/tree/dag ... 821-pr1791, but it no longer has an appveyor build available.

I appreciate all the help. For my purposes, the initially suggested version certainly appears close enough in terms of matching moves, considering the hardware differences, etc. I'm enjoying playing around with it. Thanks :)
