you should be able to explicitly upload a file of your choice as artefact using something like this: None

you should know where your latest model is located then just call task.upload_artifact on that file ?

Thank you for your help, @<1576381444509405184:profile|ManiacalLizard2> ! I tried it and got an error "Invalid task status: expected=created, status=completed ...".
I'm a bit confused about this... How to add an artifact to this task? Is it safe to call task.init() again?

Will it be recognized as a model?
Though I will try it anyway, thank you!

@<1523701070390366208:profile|CostlyOstrich36> That's literally one of my first experiments ☺ . I trained a model in Jupyter and after the training stopped, ran 'task.upload_artifact' in the next cell.

@<1580005325879119872:profile|SweetCat82> , once an experiment finished running you can't change it's status unless you reset it. I think task.upload_artifact needs to come before your task finishes.

How did you try calling it? Fetching the task via SDK and then trying to upload the artifact?
