here is what I do:
` try:
dataset = Dataset.get(
dataset_project=bucket_name,
dataset_name=dataset_name,
dataset_version=dataset_version,
)
print(
f"dataset found {dataset.project}/{dataset.name} v{dataset.version}\n(id: {dataset.id})"
)
return dataset
except ValueError:
pass

task = Task.current_task()
if task is None:
    task = Task.init(
        project_name=bucket_name, task_name=dataset_name
    )
dataset = Dataset.create(
    dataset_name=dataset_name, # has no effect
    dataset_project=bucket_name,
    dataset_version=dataset_version,
    output_uri=f"gs://{bucket_name}",
    description=f"cropped_images",
    use_current_task=True,
) `having run this once, the dataset.get will find the dataset the next time around
