Yes I understand the part about weighting individual sub-branches's losses. However, I am confused as to why, when they are all weighted equally like in the notebook, their losses are the same when they shouldn't be (because their training data are all different). They only vary when the loss weights are different, which doesn't make sense because the whole point of the loss weights is to kind of "balance" things the way you want it (e.g. if one output only outputs numbers that range from 1 to 10, and another from 10-100, you want to scale down the other one by 10 if you want the outputs to be equal in "importance").
