Worker Loss Error

Worker Loss Error

I am using the DataRobot python SDK to progrommatically train and test models on new data to get candidates for scheduled model replacement. 


it's been running fine for a while now, but I have recently received this error 

datarobot.errors.AsyncProcessUnsuccessfulError: The job did not complete successfully. Job Data: {'status': 'ERROR', 'code': 1, 'description': '', 'created': '2021-05-22T12:01:34.000901Z', 'message': 'Worker loss detected', 'statusType': '', 'statusId': '05853a89-5f2e-416a-8f2c-6b718e74591e'}


It would be great if anyone can explain what does this error mean, why does it happen, and how to avoid it in the future.

@azamrik Happy to hear you have the job running successfully now!

Also, I've been told a spot loss can be the cause of the issue even though you're using DataRobot as a managed service.

Hope this helps


I'm using DataRobot as a managed service, I'm not hosting it on my own cloud. Could the error still be caused by a spot instance loss? 


Also, yes, the job ran successfully when I resubmitted it.

Hi @azamrik - Sorry you haven't received an answer yet.


Here's what I've got for you:

message': 'Worker loss detected'

usually indicates that the job was running on a spot instance that was killed. 


Can you please try re-running the job and let me know if that succeeds?

Will look for your answer and try to keep you moving ahead.
