MSI error while running pipeline in Azure ML RRS feed

  • Question

  • Hello,

    I have been attempting to convert my Python code from Jupyter Notebooks to run in Azure Machine Learning Services.  My first step is to create a pipeline with a Notebook runner step to run a Python Notebook.  I am now getting the following error in the 70_driver_log file:  Has anyone seen this error before?

    Executing:  11%|█         | 5/47 [00:09<01:47,  2.56s/cell]WARNING - MSI: Failed to retrieve a token from '' with an error of 'HTTPConnectionPool(host='', port=39089): Max retries exceeded with url: /MSI/token//?resource= (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f5c409e8470>: Failed to establish a new connection: [Errno 111] Connection refused',))'.

    At which point, after the time out period has exceeded, the pipeline fails.

    For your reference, here is my pipeline code:

    conda_run_config.environment.python.conda_dependencies = cd

    print('run config is ready')

    source_directory = "./"

    handler = AzureMLNotebookHandler(timeout=600, progress_bar=False, log_output=True)

    cfg = NotebookRunConfig(source_directory=source_directory, notebook="process_text.ipynb",
                            handler = handler,
                            parameters={"arg1": "Machine Learning"},

    my_pipeline_param = PipelineParameter(name="pipeline_param", default_value="my_param")

    print('Source directory for the step is {}.'.format(os.path.realpath(source_directory)))
    notebook_runner_step = NotebookRunnerStep(name="training_notebook_step",
                                              params={"my_pipeline_param": my_pipeline_param},

    print("Notebook Runner Step is Created.")

    print("Notebook Run Config is created.")

    pipeline = Pipeline(workspace=ws, steps=[notebook_runner_step])

    print("Pipeline validation complete")

    pipeline_run1 = Experiment(ws, 'process_text_data').submit( pipeline, regenerate_outputs=False)
    print("Pipeline is submitted for execution")

  • Hi Melinda,

    Is this error persistent i.e does this occur when you try to run again?

    Does this error occur before the notebook_runner_step timeout expires?
