[Scidvspc-users] Using Leela-chess (LcZero) engine in scidvspc in Linux :hard to start the engine

[Jerome M. <jmo...@gm...>]

Hello all,

Like you may know, there is a new chess UCI engine called LcZeo or
leela-chess

it is the PC version alpha-zero, see :

https://en.chessbase.com/post/leela-chess-zero-alphazero-for-the-pc

and to install on scid :

https://github.com/glinscott/leela-chess/wiki/Running-Leela-Chess-Zero-in-a-Chess-GUI

I failed to install, i share here my analysis that need to be check

This engine could be compiled using (or not) the Nvidia GPU (CUDA),
compiled it on my computer using CUDA and my graphic card

Here down the console output of the run of the command (in red my command):
