Meaning of Sum

[diffmi]

I got your training script to run, but I was wondering what the meaning of "sum" is.
I.e. "2018-08-18 09:23:40 steps >>> epoch 1 batch 12 sum: 10.1"

Is that the sum of the losses in the given batch or how can I interpret it?
I looked into the code and couldn't find the information. I'm assuming it's part of the steppy toolkit?

Hi @sushimon . yeah steppy has an option to pass a list of losses with weights and then it is loss sum. Here we actually have one loss but it is still called a sum.

Anyhow it is just the epoch training loss.
