Numerai Python API

Automatically download and upload data for the Numerai machine learning competition.

This library is a Python client to the Numerai API. The interface is programmed in Python and allows downloading the training data, uploading predictions, and accessing user, submission and competitions information.

If you encounter a problem or have suggestions, feel free to open an issue.

Installation

pip install --upgrade numerapi

Usage

Numerapi can be used as a regular, importable Python module or from the command line.

Some actions (like uploading predictions or staking) require a token to verify that it is really you interacting with Numerai's API. These tokens consists of a public_id and secret_key. Both can be obtained by login in to Numer.ai and going to Account -> Custom API Keys. Tokens can be passed to the Python module as parameters or you can be set via environment variables (NUMERAI_PUBLIC_ID and NUMERAI_SECRET_KEY).

Python module

Usage example:

# some API calls do not require logging in
napi = numerapi.NumerAPI(verbosity="info")
# download current dataset
napi.download_current_dataset(unzip=True)
# get competitions
all_competitions = napi.get_competitions()
# get leaderboard for the current round
leaderboard = napi.get_leaderboard()
# leaderboard for a historic round
leaderboard_67 = napi.get_leaderboard(round_num=67)
# check if a new round has started
if napi.check_new_round():
    print("new round has started wihtin the last 24hours!")
else:
    print("no new round within the last 24 hours")

# provide api tokens
example_public_id = "somepublicid"
example_secret_key = "somesecretkey"
napi = NumerAPI(example_public_id, example_secret_key)

# upload predictions
submission_id = napi.upload_predictions("preds.csv", tournament=1)
# check submission status
napi.submission_status()
