Some parts of the pytorch model code, particular the parts involving the basic
transformer blocks and RoPE calculations, are based on or modified from those
in https://github.com/hzyhhzy/KataGo_Transformer. All of the rest of the code
(heads, trunk and block structure, and residual/convolutional blocks
and nets, metrics and loss functions, data processing, most model configs),
as well as GAB, originated from or were added by lightvector, in some cases
with minor fixes from other contributors, and are licensed the same as the rest
of katago.

Original license of the transformer parts from hzyhhzy is:
