that's the final screenshot. it just shows a bunch of normal "launching ..." steps, and then stops all the sudden.

trying to run the experiment that kept failing right now, watching logs (they go by fast)... will try to spot anything anamolous

did you take a look at my connect.sh script? I dont think it's a problem since only the controller task is the problem.

Is there some sort of culling procedure that kills tasks by any chance? the lack of logs makes me think it's something like that.

I can also try different agent versions.

I think i've narrowed this down to the ssh connection approach.

regarding the container that runs the pipeline:

• when I made it stop using autossh tunnels and instead put it on the same machine as the clearml server + used docker network host mode, suddenly the problematic pipeline started completing.
  it's just so odd that the pipeline controller task is the only one with an issue. the modeling / data-creation tasks really all seem to complete consistently just fine.

so yeah, best guess now is that its unrelated to clearml verison but rather to the connectivity of the pipeline controller task to the api server.

when I run this pipeline controller locally (also using the same ssh tunnel approach for comms), the pipeline completes just fine. so it's something specific about how its working inside the container vs on my machine, it seems.

but maybe here's a clue. after hanging like that for a while... it seems like the agent restarts (the container it runs in does not)

its odd... I really dont see tasks except the controller one dying

Hi @<1689446563463565312:profile|SmallTurkey79> !
Prior runs of this pipeline worked just fine What SDK version were you using for the prior runs? Does this still happen if you revert to that version?
Can you provide a script that imitates what you are doing?
In the pipeline you are running, are you creating new tasks/pipelines/datasets?

yeah this problem seems to happen on 1.15.1 and 1.16.2 as well, prior runs were on the same version even. It just feels like it happens absolutely randomly (but often).
just happened again to me.

The pipeline is constructed from tasks, it basically does map/reduce. prepare data -> model training + evaluation -> backtesting performance summary.

It figures out how wide to go by parsing the date range supplied as input parameter. Been running stuff like this for months but only recently did things just start... vanishing like this.

Would appreciate any help. Really need this to be more robust to make the case for company-wide adoption.

would it be on the pipeline task itself then, since that's what's disappearing? that likely the case

hoping this really is a 1.16.2 issue. fingers crossed. at this point more pipes are failing than not.

let me downgrade my install of clearml and try again.

default queue is served with (containerized + custom entrypoint) venv workers (agent services just wasn't working great for me, gave up)
