Tensboard shows all the events which it finds in the given logdir.
If I ran my training (or whatever) multiple times, I will have multiple tfevents file in the logdir. Tensorboard will show all such variable summaries merged together in a graph which looks strange.
On stdout, it writes sth like:
WARNING:tensorflow:Found more than one graph event per run. Overwriting the graph with the newest event.
WARNING:tensorflow:Found more than one "run metadata" event with tag step_0000. Overwriting it with the newest event.
How can I make it only show the summaries/events from the latest tfevents file, so that it ignores all older tfevents files?
Try putting your tfevents files into unique directories with the name of the run, as documented here
