Leela-zero: error of leela-zero on linux

[syys96]

I want to run leela-zero on my linux machine. When I followed the instructions step by step, everything was fine until the last step:
root@iZwz9dxmwcuitwtyywf7oxZ:~/leela/leela-zero# src/leelaz --weights weights.txt

OpenCL: clGetPlatformIDs

what(): clGetPlatformIDs

Could someone help me out? I turned to google and found some answers but it still doesn't work.

I guess it is because your machine does not have a GPU

It is probably because you do not have the hardware component package of opencl. You can find the list of these packages here: https://wiki.archlinux.org/index.php/GPGPU#OpenCL_Runtime (you'll have to use an equivalent for your distro though)

If you're on Ubuntu like I am, I followed the instructions found here.

Thank you for your advice@marthinwurer@Mocramis! I installed the dependent packages of opencl and this time leela-zero can run normally.
