@<1523701949617147904:profile|PricklyRaven28> Please use this patch instead of the one previously shared. It excludes the dict hack :)

Allright, a bit of searching later and I've found 2 things:

• You were right about the task! I've staged a fix here . It basically detects whether a task is already running (e.g. from the pipelinedecorator component) and if so, uses that task instead. We should probably do this for all of our integrations.
• But then I found another bug. Basically the pipeline decorator task would mess up the internal nested dict of the label mapping inside of the model config. You will probably have the same issue if you run the pipeline with my fix above.
  So for now, we're looking into the 2nd bug, because it breaks with Hugging Face models in a pipeline. Until we sort that out, I'm going to hold off on opening a PR to HF with the first fix. Makes sense?

Thanks a lot for the example, it helped tons to be able to reproduce!

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

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 tried to work on a reproducible script but then i get errors that my clearml task is already initialized (also doesn’t happen on 1.7.2)

Hi PricklyRaven28 , can you try with 1.9.1rc0?

tnx! keep me posted

thank Lior

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

i’ll try to work on something that works on 1.7.2

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

Good to hear 🙏

Hey @<1523701949617147904:profile|PricklyRaven28> , So as discussed above there were 2 issues. The first one is still waiting on the second, it's on the backlog of our devs and should be done soon(tm).

That said, in the meantime I also wanted to do fun stuff with transformers, so I've written a quick hack that deals with the bug. It's bascially 2 functions that keep track of which types of keys are in the dict.

def cast_keys_to_string(d, changed_keys=dict()):
    nd = dict()
    for key in d.keys():
        if not isinstance(key, str):
            casted_key = str(key)
            changed_keys[casted_key] = key
        else:
            casted_key = key
        if isinstance(d[key], dict):
            nd[casted_key], changed_keys = cast_keys_to_string(d[key], changed_keys)
        else:
            nd[casted_key] = d[key]
    return nd, changed_keys

def cast_keys_back(d, changed_keys):
    nd = dict()
    for key in d.keys():
        if key in changed_keys:
            original_key = changed_keys[key]
        else:
            original_key = key
        if isinstance(d[key], dict):
            nd[original_key], changed_keys = cast_keys_back(d[key], changed_keys)
        else:
            nd[original_key] = d[key]
    return nd, changed_keys

You can then use them like this:

        training_args = TrainingArguments(
            output_dir="my_awesome_model",
            learning_rate=2e-5,
            per_device_train_batch_size=16,
            per_device_eval_batch_size=16,
            dataloader_num_workers=0,
            num_train_epochs=2,
            weight_decay=0.01,
            evaluation_strategy="epoch",
            save_strategy="epoch",
            load_best_model_at_end=True
        )

        # Allow ClearML access to the training args and allow it to override the arguments for remote execution
        args_class = type(training_args)
        args, changed_keys = cast_keys_to_string(training_args.to_dict())
        training_args = args_class(**cast_keys_back(args, changed_keys)[0])

        self.trainer = Trainer(
            model=self.model,
            args=training_args,
            train_dataset=tokenized_dataset["train"],
            eval_dataset=tokenized_dataset["test"],
            tokenizer=self.tokenizer,
            data_collator=data_collator,
            compute_metrics=self.compute_metrics,
        )

        self.trainer.train()

This "hack" in combination with the patch to Huggingface from above should work 🙂 That said, it is a hack, so a production version of this should be there soon. I'll let you know when that happens!

Hi @<1523701949617147904:profile|PricklyRaven28> ! We released ClearmlSDK 1.9.1 yesterday. Can you please try it?

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?)

However, I actually do think I can already open the Huggingface PR in the meantime. It has actually relatively little to do with the second bug.

Damn it, you're right 😅

        # Allow ClearML access to the training args and allow it to override the arguments for remote execution
        args_class = type(training_args)
        args, changed_keys = cast_keys_to_string(training_args.to_dict())
        Task.current_task().connect(args)
        training_args = args_class(**cast_keys_back(args, changed_keys)[0])

We'll check it out 👍

in the meantime, we should have fixed this. I will ping you when 1.9.1 is out to try it out!

Ok. bummer to hear that it won't be included automatically in the package.

I am now experiencing a bug with the patch, not sure it's to blame... but i'm unable to save models in the pipeline.. checking if it's related

Hi @<1523701949617147904:profile|PricklyRaven28> sorry that this is happening. I tried to run your minimal example, but get a IndexError: Invalid key: 5872 is out of bounds for size 0 error. That said, I get the same error without the code running in a pipeline. There seems to be no difference between simply running the code and the pipeline (for me). Do you have an updated example, maybe also including getting a local copy of an artifact, so I can check?

It's been accepted in master, but was not released yet indeed!

As for the other issue, it seems like we won't be adding support for non-string dict keys anytime soon. I'm thinking of adding a specific example/tutorial on how to work with Huggingface + ClearML so people can do it themselves.

For now (using the patch) the only thing you need to be careful about is to not connect a dict or object with ints as keys. If you do need to (e.g. ususally huggingface models need the id2label dict somewhere) just make sure to cast it to string before connecting it to ClearML and casting it back to int directly after. So that when ClearML changes the value, it's properly taken care of 🙂 My previous sample code is still valid!

BTW the code above is from clearml github so it’s the latest

When creating it, I found that this hack should be on our side, not on Huggingface's. So I'm only going to fix issue 1 with the PR, issue 2 is ours 🙂

I appreciate it!

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

I'm working with the patch, and installing transformers from github

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

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!
