Python client reference¶

class nmpi.Client(username, password=None, job_service='https://nmpi.hbpneuromorphic.eu/api/v2/', quotas_service='https://quotas.hbpneuromorphic.eu', token=None, verify=True)¶

Client for interacting with the Neuromorphic Computing Platform of the Human Brain Project.

This includes submitting jobs, tracking job status and retrieving the results of completed jobs.

Arguments:

username, password:
	credentials for accessing the platform
job_service:	the base URL of the platform Job Service. Generally the default value should be used.
quotas_service:	the base URL of the platform Quotas Service. Generally the default value should be used.
token:	when you authenticate with username and password, you will receive a token which can be used in place of the password until it expires.
verify:	in case of problems with SSL certificate verification, you can set this to False, but this is not recommended.

user_info¶: Information about the current user, as retrieved from the Collaboratory

submit_job(source, platform, collab_id, config=None, inputs=None, command='run.py {system}')¶

Submit a job to the platform.

Arguments:

source:	the Python script to be run, the URL of a public version control repository containing Python code, or a zip file containing Python code.
platform:	the neuromorphic hardware system to be used. Either “BrainScaleS” or “SpiNNaker”
collab_id:	the ID of the collab to which the job belongs
config:	(optional) a dictionary containing configuration information for the hardware platform. See the Platform Guidebook for more details.
inputs:	a list of URLs for datafiles needed as inputs to the simulation.
command:	(optional) the path to the main Python script relative to the root of the repository or zip file. Defaults to “run.py {system}”.

job_status(job_id)¶: Return the current status of the job with ID job_id (integer or URI).

get_job(job_id, with_log=True)¶: Return full details of the job with ID job_id (integer or URI).

remove_completed_job(job_id)¶

Remove a job from the interface.

The job is hidden rather than being permanently deleted.

remove_queued_job(job_id)¶

Remove a job from the interface.

The job is hidden rather than being permanently deleted.

queued_jobs(verbose=False)¶

Return the list of jobs belonging to the current user in the queue.

Arguments:

verbose:	if False, return just the job URIs, if True, return full details.

completed_jobs(collab_id, verbose=False)¶

Return the list of completed jobs in the given collab.

Arguments:

verbose:	if False, return just the job URIs, if True, return full details.

download_data(job, local_dir='.', include_input_data=False)¶

Download output data files produced by a given job to a local directory.

Arguments:

include_input_data:
job:	a full job description (dict), as returned by get_job().
local_dir:	path to a directory into which files shall be saved.
	also download input data files.

copy_data_to_storage(job_id, destination='collab')¶

Copy the data produced by the job with id job_id to Collaboratory storage or to the HPAC Platform. Note that copying data to an HPAC site requires that you have an account for that site.

Example:

To copy data to the JURECA machine:

client.copy_data_to_storage(90712, "JURECA")

To copy data to Collab storage:

client.copy_data_to_storage(90712, "collab")

create_data_item(url)¶: Register a data item with the platform.

create_resource_request(title, collab_id, abstract, description=None, submit=False)¶: Create a new resource request. By default, it will not be submitted.

edit_resource_request(request_id, title=None, abstract=None, description=None, submit=False)¶: Edit and/or submit an unsubmitted resource request

list_resource_requests(collab_id, status=None)¶: Return a list of resource requests for the Neuromorphic Platform

list_quotas(collab_id)¶: Return a list of quotas for running jobs on the Neuromorphic Platform

my_collabs()¶: Return a list of collabs of which the user is a member.
