Weight decay only applied when printing averaged stats

Hi, I'm looking through opt.py and noticed that the code 
`
if args.weight_decay_sh < 1.0:
    grid.sh_data.data *= args.weight_decay_sigma
if args.weight_decay_sigma < 1.0:
    grid.density_data.data *= args.weight_decay_sh
`
Only runs inside
`if (iter_id + 1) % args.print_every == 0:` 
Is it intentional to only update weight decay when printing?
