# Loss normalize(or unify units) when using multiple loss

Hi guys,

If I want to use two combined losses, (L = loss1 + loss2)
and suppose the decimal unit between two losses are different,
for example, loss 1 is around 0.01~0.09 and loss2 is around 1~9,
Do I need to unify the units of two losses?
The loss is MSE.
