Provenance¶

class ctapipe.core.Provenance(*args, **kw)[source]¶

Bases: object

Manage the provenance info for a stack of activities

use start_activity(name) to start an activity. Any calls to add_input_file or add_output_file will register files within that activity. Finish the current activity with finish_activity.

Nested activities are allowed, and handled as a stack. The final output is not hierarchical, but a flat list of activities (however hierarchical activities could easily be implemented if necessary)

Attributes Summary

`active_activity_names`
`current_activity`
`finished_activities`
`finished_activity_names`
`instance`
`provenance`	returns provenence for full list of activities

Methods Summary

`activity`(name)	context manager for activities
`add_config`(config)	add configuration parameters to the current activity
`add_input_file`(filename[, role])	register an input to the current activity
`add_output_file`(filename[, role])	register an output to the current activity
`as_json`(**kwargs)	return all finished provenance as JSON.
`clear`()	remove all tracked activities
`finish_activity`([status, activity_name])	end the current activity
`start_activity`([activity_name])	push activity onto the stack

provenance¶: returns provenence for full list of activities

Methods Documentation

activity(name)[source]¶: context manager for activities

add_config(config)[source]¶

add configuration parameters to the current activity

Parameters

config: dict: configuration parameters

add_input_file(filename, role=None)[source]¶

register an input to the current activity

Parameters

filename: str: name or url of file
role: str: role this input file satisfies (optional)

add_output_file(filename, role=None)[source]¶

register an output to the current activity

Parameters

filename: str: name or url of file
role: str: role this output file satisfies (optional)

as_json(**kwargs)[source]¶: return all finished provenance as JSON. Kwargs for json.dumps may be included, e.g. indent=4

clear()[source]¶: remove all tracked activities

finish_activity(status='completed', activity_name=None)[source]¶: end the current activity

start_activity(activity_name='/home/docs/checkouts/readthedocs.org/user_builds/ctapipe/envs/v0.19.2/bin/python')[source]¶: push activity onto the stack
