local variable 'neg_grad_ma' referenced before assignment when momentum_type is not "pnm" #34

Bug in line 904 that requires adding "if self.momentum_pnm:" before pnmomentum is calculated.

I'm trying to diagnose Nans I get with a large learning rate after some batches and make Ranger21 perform as the base AdamW (if it's possible in the first place).
