Can I configure tensorboard to start with no smoothing? The smoothing can hide overfitting. If there was a command line option, or if tensorboard looked in a location like ~/.tensorboard/config.ini that would be great.
But with the default smoothing it looks like
you've got to look at the second one closely to see your overfitting
or what would be even better, is to configure this per plot. Maybe even when making the SummaryWriter in the code.
