Runner
- class health_ml.Runner(project_root)[source]
Bases:
object
This class contains the high-level logic to start a training run: choose a model configuration by name, submit to AzureML if needed, or otherwise start the actual training and test loop.
- Parameters
project_root (
Path
) – The root folder that contains all of the source code that should be executed.
Methods Summary
- rtype
Dict
[str
,str
]
additional_run_tags
(script_params)Gets the set of tags that will be added to the AzureML run as metadata.
Parses the command line arguments, and creates configuration objects for the model itself, and for the Azure-related parameters.
run
()The main entry point for training and testing models from the commandline.
run_in_situ
(azure_run_info)Actually run the AzureML job; this method will typically run on an Azure VM.
Submit a job to AzureML, returning the resulting Run object, or exiting if we were asked to wait for completion and the Run did not succeed.
validate
()Runs sanity checks on the whole experiment.

- parse_and_load_model()[source]
Parses the command line arguments, and creates configuration objects for the model itself, and for the Azure-related parameters. Sets self.experiment_config to its proper values. Returns the parser output from parsing the model commandline arguments.
- Return type
ParserResult
- Returns
ParserResult object containing args, overrides and settings
- run()[source]
The main entry point for training and testing models from the commandline. This chooses a model to train via a commandline argument, runs training or testing, and writes all required info to disk and logs.
- Return type
Tuple
[LightningContainer
,AzureRunInfo
]- Returns
a tuple of the LightningContainer object and an AzureRunInfo containing all information about the present run (whether running in AzureML or not)
- run_in_situ(azure_run_info)[source]

datasets are mounted.
- Return type
None
- submit_to_azureml_if_needed()[source]
