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. It works for both, the main competition and the newer Numerai Signals competition.
If you encounter a problem or have suggestions, feel free to open an issue.
pip install --upgrade numerapi
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
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 (
Usage example - main competition
import numerapi # 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 current leaderboard leaderboard = napi.get_leaderboard() # check if a new round has started if napi.check_new_round(): print("new round has started within 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.NumerAPI(example_public_id, example_secret_key) # upload predictions model_id = api.get_models()['uuazed'] napi.upload_predictions("preds.csv", model_id=model_id) # check submission status napi.submission_status(model_id) # increase your stake by 1.2 NMR napi.stake_increase(1.2) # convert results to a pandas dataframe import pandas as pd df = pd.io.json.json_normalize(napi.daily_user_performances("uuazed"), sep="-")
Usage example - Numerai Signals
import numerapi napi = numerapi.SignalsAPI() # get current leaderboard leaderboard = napi.get_leaderboard() # setup API with api tokens example_public_id = "somepublicid" example_secret_key = "somesecretkey" napi = numerapi.SignalsAPI(example_public_id, example_secret_key) # upload predictions model_id = api.get_models()['uuazed'] napi.upload_predictions("preds.csv", model_id=model_id) # get daily performance as pandas dataframe import pandas as pd df = pd.DataFrame(napi.daily_user_performances("uuazed"))
Command line interface
To get started with the cli interface, let's take a look at the help page:
