Loss logging issue with Comet
On Comet multiple different values of the loss are logged per epoch. This can be seen by opening the panels of a training, like this one.
Selecting epoch to be displayed on the x axis, navigating to the train_loss and exporting the graph data as a JSON will show repeated values for the x axis.
I included two JSONs showing a training loss and a valuation loss log exported like this. The first shows the issue reported and the second shows what one would expect the data for a 2D graph to look like.
