I'm able to reproduce, but your workaround seems to be the best one for now. I tried launching with clearml-task command as well, but we have the same issue there: only argparse arguments are allowed.
AgitatedDove14 any better workaround for this, other than waiting for the jsonargparse issue to be fixed?

I commented this and a bit more on an existing issue: https://github.com/allegroai/clearml/issues/403#issuecomment-1316689416

I found a hack! 🎉 See the issue for details: https://github.com/allegroai/clearml/issues/403#issuecomment-1317362482

HomelyShells16 Thanks for the detailed write-up and minimal example. I'm running it now too

Hi HomelyShells16 How about doing things this way? does it work for you?
` class ClearmlLightningCLI(LightningCLI):
def init(self, *args, **kwargs):
Task.add_requirements("requirements.txt")
self.task = Task.init(
project_name="example",
task_name="pytorch_lightning_jsonargparse",
)
super().init(*args, **kwargs)

def instantiate_classes(self, *args, **kwargs):
    super().instantiate_classes(*args, **kwargs)
    self.task.execute_remotely(queue_name="Eugene")

if name == "main":
ClearmlLightningCLI(ImageClassifier, seed_everything_default=42, save_config_overwrite=True, run=True) `

Thanks SmugDolphin23 for the suggestion.
Sadly this does not solve the problem of having Namespace s inside the config, which cannot be parsed by jsonargparse when running remotely. The Error message is the same as shown https://github.com/allegroai/clearml/issues/403#issuecomment-1316689416 .

HomelyShells16 looks like some changes have been made to jsonargparse and pytorch_lightning since we released this binding feature. could you try with jsonargparse==3.19.4 and pytorch_lightning==1.5.0 ? (no namespace parsing hack should be needed with these versions I believe)

Awesome, thanks! Make sure to check out the linked issue, as I have added more findings there

Also, feel free to open a GH ticket (thank you for reporting this issue :d)
