Hello PicoChess players, 

I just installed PicoChess v4 from Randy's latest Desktop Image on a Pi4 B 4GB. Tiny Gyal does not respond after a few moves. I saw this already in an earlier version. Can someone please check on a similar setup?

Thanks
Ralf

Hi all,

I just found, that the weights file is missing:

https://github.com/dkappe/leela-chess-weights/files/4432261/tinygyal-8.pb.gz

It should be placed in /opts/picochess/engines/lc0_weights

Kind Regards
Ralf

Yes. It seems to be missing from the lc0_weights.tar.gz resource file which is downloaded when installing v4. Perhaps Johan can add it. I'll update my images.

Thanks for the heads-up, Ralf.

Randy
