Lc0 - macOS binary requested

Hi there. I am very interested in the Leela project, but I am not a programmer and cannot compile Lc0 by myself.
(I saw there is a description for Mac-users-:))
Please can anybody provide us with the binary for macOS?
Please can you post it like the windows Versions under: https://github.com/LeelaChessZero/lc0/releases.
Thanks in Advance.
😀

Hi there, maybe you should place your request on these LC0 related sites:

https://discordapp.com/invite/pKujYxD
https://groups.google.com/forum/#!forum/lczero
https://github.com/LeelaChessZero/lc0/issues

And if you are running macOS 10.14 Mojave,
you could give your OS vendor a hint
to continue support for OpenCL or CUDA,
to make a gpu programmers life easier.

Hi Stepphen Wolf,

Compiling Lc0 was initially quite difficult in previous versions, and required a decent amount of modifications, but that is no longer true; However, this does assume you have downloaded the required dependencies. Assuming you have nothing, you'll first need to install xcode (from the app store). Then in terminal, you'll need these, and if not, they'll be helpful compiling other engines :

# Download Homebrew (allows for easy installation of different packages on mac)
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homeb ... er/install)"

# Downloads via Homebrew
brew install python3
brew install meson
brew install ninja
brew install llvm --with-toolchain
brew install cmake
brew install protobuf

# Download Python Packages
pip install numpy
pip install wheel
pip install six
pip install setuptools
pip install tensorflow

# Download Lc0 Source Code & Compile
git clone https://github.com/LeelaChessZero/lc0.git
cd lc0/
./build.sh

Hi Still_the_tea

thank you for your reply. But I was not successful.
Please can you Compile a macOS binary and post it.
How should I proceed with CUDA?

by Typing these commands :

pip install numpy
pip install wheel
pip install six
pip install setuptools
pip install tensorflow

it always came: "command not found"

during compiling also came several error Messages...

I can you provide with the meson-log-text-file via PM if you wish-:)

Compiling yourself is the only way to ensure you have the correct dependancies installed on your computer. Without such dependancies, any binary that anyone posts will never work on your mac. It's that simple. Furthermore, to compile for OpenCL or Cuda is a little trickier and requires even more dependancies. Without Cudo or OpenCL, you will have to use open blas which is CPU based. At that point, it will be painfully slow. and hundreds of Elo weaker than those with high end GPU's. Now, if for some reason you sincerely believe your mac has magically acquired all of the aforementioned dependancies with out any successful effort on your part, here's a mac binary you can try..

lc0 in action under xBoard on a 2010 Mac Pro .

Here's a code snippet. that will will tell you if have OpenCL hardware.

Code: Select all

#include <stdio.h>
#include <stdlib.h>
#include <OpenCL/opencl.h>

int main(int argc, char* const argv[]) {
	cl_uint num_devices, i;
	clGetDeviceIDs(NULL, CL_DEVICE_TYPE_ALL, 0, NULL, &num_devices);
	
	cl_device_id* devices = calloc(sizeof(cl_device_id), num_devices);
	clGetDeviceIDs(NULL, CL_DEVICE_TYPE_ALL, num_devices, devices, NULL);
	
	char buf[128];
	for (i = 0; i < num_devices; i++) {
		clGetDeviceInfo(devices[i], CL_DEVICE_NAME, 128, buf, NULL);
		fprintf(stdout, "Device %s supports ", buf);
		
		clGetDeviceInfo(devices[i], CL_DEVICE_VERSION, 128, buf, NULL);
		fprintf(stdout, "%s\n", buf);
	}
	
	free(devices);
}
call it hello.c
compile with this:
clang -framework OpenCL hello.c -o hello

you will get warnings that OpenCL for the mac is going away - not great news for macOS users

Code: Select all

Dear MikeB,

thanks for your detailed Message with your help.
Unfortunately, I am not that expert to be able to Compile the binary (thanks for your uploaded binary, but I did not work :wink: ).
I also Understand that there are several libraries needed to run lc0 on macOS.

But why not making a complete bundle for some dummies like me where all the requested stuff is inside to be run on a mac?

Thanks again, Steppenwolf

Steppenwolf,
I am 100% certain I can walk you through this over a few days if you are gamed for it. We might as well do it here , so anybody else having issues with macOS. I am partial to MacPorts over Homebew , but they both will work. In theory, you install it without MacPorts or HomeBrew, but those are tools to make installing any open source program much easier. So are you ready ?

Dear MikeB,

Great thanks! :D
I am ready for it.

Please think, that I am not that programmer expert. I have Mojave 10.14.5 and a macbook pro (mid 2014) with no CUDA Driver.
Is there already one for Mojave?
If you need further Information...
