Targets

Targets are products of Luigi tasks. These targets are checked for existance prior to running a tasks. This task is only run if any of the targets does not exist. A task also cannot exit with success when the target isn’t created after the task was run.

class targets.numerai_submission.SubmissionTarget(path, public_id, secret)

Implements a submission target to “output” predictions from luigi tasks on the numer.ai servers.

__init__(path, public_id, secret)

Creates a new SubmissionTarget.

Param:path (str): local path to the predictions csv file Param:public_id (str): public_id as reported by the numer.ai website when creating API credentials Param:secret (str): secret as reported by the numer.ai website when creating API credentials

exists()

Checks if a submission for the file named path was uploaded.

NB: the filename as reported by the server is appended by a random string (before the file extension), and we can just access the file that was submitted last. This might result in double uploads for the same file.

submit()

Submits the predictions to the numer.ai servers and tries to report back the status.
