why comment loss_xyz during train stage? #128

I think it's important to supervise joints in camera coordinate during train stage, but I found you comment loss_xyz, this is confusing to me.

We can implicitly supervise xyz by directly supervising uvd and camera, and in experiments, we find that directly supervising xyz sometimes harms the prediction of camera.

Got it, Thank you for your kind reply！
