[Feature]: Ability to log isolated events #3409

Open epignatelli opened 2 years ago

epignatelli commented 2 years ago

Description

It would be really handy to have the ability to log instantaneous events, especially in reinforcement learning projects. For example, wandb.log({"Events"; "Experience Replay starts"}, step=5000), or wandb.log({"Events"; "First reward"}, step=389).

Suggested Solution

I am imagining a table of events:

Event step
First reward 389
Experience Replay starts 5000

Alternatives

You can log a step independently, I.E.

wandb.log({"event": "thing", "mystep": 321})

Then you can choose a custom x-axis or filter metrics. For categorical metrics like this we don't have any native visualizations but you could use custom charts to visualize, or just pull the data via the api.

Tha sounds good. If there is any way I can plot a vertical line at a specific x coordinate, I think this is already solved.
