Could you please run the misbehaving example, try to add a breakpoint in clearml/backend_interface/task/task.py in Task.update_output_model on the line with url = output_model.update_weights( , and tell me what the value of model_path is? In case you're using virtual environments, clearml library should be installed somewhere in <virtual env directory>/lib/python3.10/site-packages/clearml/

i believe this is because of transformer’s integration:

Automatic ClearML logging enabled.
ClearML Task has been initialized.

when a task already exists

@<1523701435869433856:profile|SmugDolphin23> @<1523701087100473344:profile|SuccessfulKoala55> Yes, the second issue still consists, currently breaking our pipeline

Hi PricklyRaven28 ! What dict do you connect? Do you have a small script we could use to reproduce?

Yes, and the old version only works without the patch.
I see the model on the artifacts tab, but it's not actually uploaded.

It should, but please check first. This is some code I quickly made for myself. It did make tests for it, but it would be nice to hear from someone else that it worked (as evidenced by the error above 😅 )

Thanks! I'm checking now, but might take a little (meeting in between)

hi, yes we tried with the same result

Hi PricklyRaven28 , can you try with 1.9.1rc0?

This is the next step not being able to find the output of the last step

ValueError: Could not retrieve a local copy of artifact return_object, failed downloading 

that makes more sense 🙂
would this work now as a workaround until the version is released?

I'm getting really weird behavior now, the task seems to report correctly with the patch... but the step doesn't say "uploading" when finished... there is a "return" artifact but it doesn't exist on S3 (our file server configuration)

tnx! keep me posted

Hey 🙂
Any updates on this? We need to use a new version of transformers because of another bug they have in an old version. so we can’t use the old transformers version anymore.

@<1523701118159294464:profile|ExasperatedCrab78>
Hey again 🙂
I believe that the transformers patch wasn’t released yet right? we are getting into a problem where we need new features from transformers but can’t use because of this

I am currently on vacation, I'll ask my team mates. But if not I'll get to it next week

Now worries! Just so I understand fully though: you were already using the patch with success from my branch. Now that it has been merged into transformers main branch you installed it from there and that's when you started having issues with not saving models? Then installing transformers 4.21.3 fixes it (which should have the old clearml integration even before the patch?)

` from clearml.automation import PipelineDecorator
from clearml import TaskTypes

This isn’t a real working example, but it shows that on clearml 1.7.2 it passed initialization part (and has an error on training stuff which is ok)

And on 1.9.0 it errors before on
TypeError: unsupported operand type(s) for +=: 'NoneType' and 'str'

Hey @<1523701949617147904:profile|PricklyRaven28> I'm checking! Have you updated anything else and on which exact commit of transformers are you now?

Looks like the first issue has been solved 🙂

i think the second one still consists, still checking

of course

confirming that only downgrading to transformers==4.21.3 without the patch worked....
This is a time bomb that eventually we won't be able to ignore... we will need to use new transformers code

S3 as it should be

thank Lior

yeah, it gets to that error because the previous issue is saved…i’ll try to work on a new example

sounds good 🙂 I’ll soon check if this fixes our issue and update you

We'll check it out 👍

Hi @<1523701949617147904:profile|PricklyRaven28> just letting you know I still have this on my TODO, I'll update you as soon as I have something!
