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?
