I may understand your issue. Look like you attempted to run Banksia (the console app) with Lc0. Sorry to make you ambiguous since there are two different Banksia apps. Now instead of one we have 3 apps involving

Let me explain:

- Leela Chess Zero (Lc0) is a console (Command Line Interface - CLI) chess engine. It runs without any graphics. If you are not a chess developer you should not play directly with it since command lines for it (a UCI protocol engine) are usually very long (and boring). Instead, a normal user should use a chess GUI to play with it.

As I said in an above post, you should run Lc0 directly for the first time only right after downloading, mainly to give it and its libraries permissions to run (to run, go to lc0 folder and click on file "lc0")

- Banksia (download from github.com) is a console app too. The purpose of that app is to help users make tournaments between chess engines but not human players. Don't use that app if you want to play vs Lc0 as a human

- Banksia GUI (Banksia + Graphical User Interface) is a chess GUI. It is what you need to vs Lc0.

Steps:

1) Download and run BanksiaGUI
- Download BanksiaGUI (temporary download page: https://banksiagui.com/preview-versions/)
- From Finder, go to download folder, click on the download zip file to unzip it. You will see the file "BanksiaGui.app"
- Control-click (click when holding Control key) to that app to popup a dialog -> click button Open to allow the app running

You should see the bellow screen of Banksia GUI:


2) Integrate Lc0 to BankisiaGUI
- open menu File->Preferences to open Settings Dialog->Engines tab
- Click + button (button with image of plus) and follow its instruction to add Lc0

3) Create a game to vs Lc0
- open menu File -> Game setup. Select the first box as Human and Lc0 for the second one -> OK
Now you can play white side vs Lc0 black side

Hope it helps

Thanks - the Banksia GUI for playing against lc0 works perfectly on Catalina.

You are to be congratulated for having built this and hats off to you.

Bad news.

BanksiaGUI with lc0 crashed after I played e4, lc0 played e5.

The good news is, however, upon restart, Banksia restarted lc0 at the previous position and the game has continued.

Still, the crash concerns...

This is with all the default settings, no time changes, etc.

I was away from the playing area for about an hour when I came back and saw the crash.

Have played a couple moves in the Ruy Lopez further.

Sequence:

Stuart vs. Leela at default BanksiaGUI time controls

e4 e5
Nf3 Nc6 <=== crash occurred a some point after the computer's Nc6
Bb5 a6
Bxc6 dc

By the way, the interface is wonderful.

Very happy to see BanksiaGUI on Apple Catalina working.

Hi
Looking for someone to program chess variants using LC0 programming architecture

MAIL ME TO musketeerchess @. Gmail.com

All of this is solved here.

Have latest Leela with a recently network 1 up on two Mac's running Catalina.

One is the 2017 Mac 13" and the other is the 109 Mac 16".

So now I have some good sparring partners as I am doing an enormous amount of travel and there's nothing like killing time than chess.

--Stuart

P.S. Thanks to Banksia author and the Leela community and this board for the various assistance. The program has an entertaining playing style
and I have renewed my membership in USCF with the thought that, perhaps, some day, I'll play another rated game...
