optimizer->options.learning_rate_ = original_learning_rate * decay_level;

Just got this error on the Windows CI build, but not the Ubuntu one. It's building fine on my home PCs too. Looking into it now.

Maybe an incompatibility with PyTorch 1.3?

Omegastick commented

Looks like pytorch/pytorch@ce3d024 broke it. I'll get a fix up once I've built PyTorch 1.3 on my PC.

found that if change to
optimizer->options.learning_rate(original_learning_rate * decay_level); //options.learning_rate_
compiles without errors

Should be fixed in e1844a1.
