计算平台选择

最新版本为 v1.8.2

有三种版本: OpenCL vs CUDA vs Eigen

项目说明中的描述如下

KataGo has three backends, OpenCL (GPU), CUDA (GPU), and Eigen (CPU).

The quick summary is:

Use OpenCL if you have any good or decent GPU.

Use Eigen with AVX2 if you don’t have a GPU or if your GPU is too old/weak to work with OpenCL, and you just want a plain CPU KataGo.

Use Eigen without AVX2 if your CPU is old or on a low-end device that doesn’t support AVX2.

You can try CUDA you have a top-end NVIDIA FP16 + tensor-core GPU and you are willing to go through the hassle to install CUDA+CUDNN. It might or might not be faster than OpenCL, you can try it out to see.

因此对于有 GPU 的电脑来说，选择 OpenCL 比较好，如下图

最近的有新模型发布的版本为 v1.4.5，截图如下

项目说明中的描述

Which Network Should I Use?

For weaker or mid-range GPUs, try the final 20-block network.

For top-tier GPUs and/or for the highest-quality analysis if you’re going to use many thousands and thousands of playouts and long thinking times, try the final 40-block network, which is more costly to run but should be the strongest and best.

If you care a lot about theoretical purity - no outside data, bot learns strictly on its own - use the 20 or 40 block nets from this release, which are pure in this way and still much stronger than Leela Zero, but also not quite as strong as these final nets here.

If you want some nets that are much faster to run, and each with their own interesting style of play due to their unique stages of learning, try any of the “b10c128” or “b15c192” Extended Training Nets here which are 10 block and 15 block networks from earlier in the run that are much weaker but still pro-level-and-beyond.

And if you want to see how a super ultra large/slow network performs that nobody has tested until now, try the fat 40-block 384 channel network mentioned a little up above.

总结下来就是, b20,30,40 依次变强, 有显卡的就选择b40的模型就好，如下图
