Here are a few crude but functional tensorboard file manipulation tools - they definitely could use some love (I adapted someone else' scripts) but they are good enough for an occasional use. Each script contains the usage and examples inside.
- tb-remove-events-by-group.py - remove whole sub-grops of events
- tb-remove-events-by-tag.py - remove specific events by name
- tb-rename-events.py - rename events
