its odd... I really dont see tasks except the controller one dying
trying to run the experiment that kept failing right now, watching logs (they go by fast)... will try to spot anything anamolous
the workers connect to the clearml server via ssh-tunnels, so they all talk to "localhost" despite being deployed in different places. each task creates artifacts and metrics that are used downstream
N/A (still shows as running despite Abort being sent)
yeah locally it did run. I then ran another via UI spawned from the successful one, it showed cached steps and then refused to run the bottom one, disappearing again. No status message, no status reason. (not running... actually dead)
do you have any STATUS REASON under the INFO section of the controller task?
ah. a clue! it came right below that but i guess out of order...
that id is the pipeline that failed
Hi @<1689446563463565312:profile|SmallTurkey79> ! I will take a look at this and try to replicate the issue. In the meantime, I suggest you look into other dependencies you are using. Maybe some dependency got upgraded and the upgrade now triggers this behaviour in clearml.
would it be on the pipeline task itself then, since that's what's disappearing?
I will do some experiment comparisons and see if there are package diffs. thanks for the tip.
yeah, it just shows what I see in the Console, but then immediately goes back to polling for more work (so... instead of running backtest, it exits, no completion message)
I have tried other queues, they're all running the same container.
so far the only thing reliable is pipe.start_locally()
odd bc I thought I was controlling this... maybe I'm wrong and the env is mis-set.
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.
default queue is served with (containerized + custom entrypoint) venv workers (agent services just wasn't working great for me, gave up)
hoping this really is a 1.16.2 issue. fingers crossed. at this point more pipes are failing than not.
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.
it happens consistently with this one task that really should be all cache.
I disabled cache in the final step and it seems to run now.
it's pretty reliably happening but the logs are just not informative. just stops midway
do you have the agent logs that is supposed to run your pipeline? Maybe there is a clue there. I would also suggest to try enqueuing the pipeline to some other queue, maybe even run the agent on your on machine if you do not already and see what happens
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?
damn, it just happened again... "queued" steps in the viz are actually complete. the pipeline task disappeared again without completion, logs mid-stream.
when i run the pipe locally, im using the same connect.sh script as the workers are in order to poll the apiserver via the ssh tunnel.
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)
would it be on the pipeline task itself then, since that's what's disappearing? that likely the case
I really can't provide a script that matches exactly (though I do plan to publish something like this soon enough), but here's one that's quite close / similar in style:
None where I tried function-steps out instead, but it's a similar architecture for the pipeline (the point of the example was to show how to do a dynamic pipeline)
