There seems to be a difference between 0 contempt and NO contempt.

Issues with source of new Leela

There are some issue with source of Leela ver.0.26.0.
In src\neural\network.h - illegal name.
in src\mcts\stoppers\factory.cc - unresolved external.
I could compile lc0v0.26.0 with Time manager = "smooth" only.
