[azureml python sdk v2] access files in URI_FOLDER output after job has finished?

先从 issue 中展示的 Azure ML v2 SDK job 和 NodeOutput API 开始，然后将其与 MlflowClient 访问路径进行比较。在 job ivory_octopus_yd6by49kxf 完成后，记录或演示一种以编程方式列出、检索和下载 URI_FOLDER 文件的方法，即视为完成。

I have a training job that persists some files in an URI_FOLDER output.
How can I access those through the v2 SDK API after the job has finished?

1. job setup

The output is set up like this in the command:

job = command(
    # ...
    outputs=dict(
        outputs=Output(type=AssetTypes.URI_FOLDER, mode='rw_mount'),
    ),
    command="python training_script.py " + 
            "--outputs_dir ${{outputs.outputs}} " +
            # ...other arguments...
)

This seems to work fine, the corresponding folder is mounted correctly and accessible in the training script.

2. training script

In the training script, I persist a dataframe like this:

parser.add_argument("--outputs_dir", dest="outputs_dir", default=DEFAULT_MODEL_DIR)
# ...
some_dataframe.to_csv(os.path.join(args.outputs_dir, 'some_dataframe.csv'), index=True)

This works fine.

3. resulting dataset

After the job has finished, the outputs are available as a dataset.
This is what is shown in Azure ML Studio in the "Overview" tab for job ivory_octopus_yd6by49kxf:

The dataset is successfully stored in the workspaceblobstore datastore. I checked it in the Azure ML Studio and it looks fine.

4. accessing the persisted data

After the job has finished, I access the run using a MlflowClient()

MLFLOW_TRACKING_URI = ml_client.workspaces.get(name=ml_client.workspace_name).mlflow_tracking_uri
mlflow.set_tracking_uri(MLFLOW_TRACKING_URI)
mlflow_client = MlflowClient()

mlflow_run = mlflow_client.get_run("ivory_octopus_yd6by49kxf")

or

run = ml_client.jobs.get('ivory_octopus_yd6by49kxf')
# returns NodeOutput class

How can I programmatically list / get / download the outputs connected to the job?

Thanks!
