Re: LCZero is using my cores, not my GPU.

Hard to give specific recommendations, but at this point generally something NVIDIA GTX 1060, 1070, 1080 or 1080 Ti based, basically depending on how much you want to spend. Above the 1080 Ti and below the 1060 the price/performance curve drops off rapidly. As for the different vendors out there, c...

Are you able to update your video driver? No idea if that's the cause, but this is extremely old.
I'll give it a whirl.

If I was to buy a video card just to train Leela, what would be recommend? I can get it through work; so may as well.

Re: LCZero is using my cores, not my GPU.

My CPU training is working. Thought I'd try the GPU (it's not up to much but I could upgrade it) and get this:- Args: [C:\Users\Colin\Projects\leela\gpu-win/lczero --weights=networks\bb479ee94f3fb39fefb5a5b6db75bd57fd614dbd275424173 0d7cb377ebb5f68 -t1 --randomize -n -v800 -lC:\Users\Colin\Projects\...

Re: Leela Chess Zero + Google Colab

Well that was easy!

If like me you are thinking "OK but WTF is google colab", don't worry - it's about 5 clicks to setup and start it training.

Re: Roller (just for fun)

I did a tweak to start with short rollouts (2 ply!) and exponentially increase (x1.00003) from there to a ceiling of 200. this allows it to avoid close mates a bit better. If the ply limit is reached before W/L/D it tosses a coin and returns W or L. It's playing a true random mover now (called Rolle...
