Hey everyone, I have been trying to get the pytorch lightning CLI to work with remote task execution, but it just won't work. I took the https://github.com/allegroai/clearml/blob/master/examples/frameworks/jsonargparse/pytorch_lightning_cli.py and extended it like this:
` task = Task.init(project_name="example", task_name="pytorch_lightning_jsonargparse")

  • task.execute_remotely(queue_name="single-gpu") # that's our internal queue
    LightningCLI(ImageClassifier, seed_everything_default=42, save_config_overwrite=True, run=True) When running this experiment I get the following error: Traceback (most recent call last):
    File "/home/clearml/.clearml/venvs-builds.1/3.9/task_repository/clearml.git/examples/frameworks/jsonargparse/pytorch_lightning_cli.py", line 120, in <module>
    LightningCLI(ImageClassifier,
    File "/home/clearml/.clearml/venvs-builds.1/3.9/lib/python3.9/site-packages/pytorch_lightning/utilities/cli.py", line 157, in init
    super().init(*args, **kwargs)
    File "/home/clearml/.clearml/venvs-builds.1/3.9/lib/python3.9/site-packages/pytorch_lightning/cli.py", line 346, in init
    self.subcommand = self.config["subcommand"] if run else None
    File "/home/clearml/.clearml/venvs-builds.1/3.9/lib/python3.9/site-packages/jsonargparse/namespace.py", line 200, in getitem
    leaf_key, parent_ns, _ = self._parse_required_key(key)
    File "/home/clearml/.clearml/venvs-builds.1/3.9/lib/python3.9/site-packages/jsonargparse/namespace.py", line 161, in _parse_required_key
    raise KeyError(f'Key "{key}" not found in namespace.')
    KeyError: 'Key "subcommand" not found in namespace.' `
    Running locally is no problem at all.

To me it seems like the command line args are not passed when running the script remotely.
Any ideas how to fix this?

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

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) `

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

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)

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

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 .

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?
