Hi, I have a question about how to get notified when a task finishes running.

We are creating training tasks programatically on ClearML Server. It is relatively easy to do through directly accessing the ClearML Server API.

However, we'd like some way to be notified when the training task has finished. Is there some way to register a callback URL when creating a task? I'm imaging that ClearML server would send a GET HTTP request to this URL when training has finished. (Looking through the ClearML Server documentation, I couldn't find anything like this.)

Alternatively, since we are creating the training tasks programatically, in theory we could modify the training script to ping a given URL when training is finished. However, ideally we wouldn't need the training script to know anything about our server setup (which machine to ping, etc).

Another possibility would be to run a process somewhere that periodically polls ClearML Server for tasks that have recently finished. I'm imagining something similar to the Slack Notification example: https://github.com/allegroai/clearml/blob/0c017a73310cac0e699f3b1a61c462a5397706b6/examples/services/monitoring/slack_alerts.py . The downside of this is that we need another process running somewhere specifically doing this.
