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.
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 - main competition
import numerapi
# some API calls do not require logging in
napi = numerapi.NumerAPI(verbosity="info")
# download current dataset => also check `https://numer.ai/data`
napi.download_dataset("v4/train.parquet", "train.parquet")
# 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 12hours!")
else:
print("no new round within the last 12 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 = napi.get_models()['uuazed']
napi.upload_predictions("preds.csv", model_id=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.DataFrame(napi.daily_user_performances("uuazed"))
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 = napi.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"))
# using the diagnostics tool
napi.upload_diagnostics("preds.csv", model_id=model_id)
# ... or using a pandas DataFrame directly
napi.upload_diagnostics(df=df, model_id=model_id)
# fetch results
napi.diagnostic(model_id)
