[PantherHawk]

what's the problem
Match case syntax is not compatible with earlier Python versions.

training-operator/sdk/python/kubeflow/storage_initializer/storage.py

Lines 7 to 28 in f8f7363

	match model_provider:
	case "hf":
	hf = HuggingFace()
	hf.load_config(model_provider_parameters)
	hf.download_model_and_tokenizer()
	case _:
	return "This is the default case"
	def dataset_factory(dataset_provider, dataset_provider_parameters):
	match dataset_provider:
	case "s3":
	s3 = S3()
	s3.load_config(dataset_provider_parameters)
	s3.download_dataset()
	case "hf":
	hf = HuggingFaceDataset()
	hf.load_config(dataset_provider_parameters)
	hf.download_dataset()
	case _:
	return "This is the default case"

what's the fix?
Use if-else instead.

Thank you for reporting this!

That makes sense. We should replace the match with if-else, and then we should cherry-pick it to the latest release-branch.

Hi @tenzen-y , I think the contributor of PR #2099 has been inactive for 2 weeks. Will it be fine If I take this up and create a new PR?
