numerapi 2.22.0

Automatically download and upload data for the Numerai machine learning competition

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)

Command line interface

To get started with the cli interface, let's take a look at the help page:

$ numerapi --help
Usage: numerapi [OPTIONS] COMMAND [ARGS]...

  Wrapper around the Numerai API

  Options:
    --help  Show this message and exit.

  Commands:
    account                   Get all information about your account!
    check-new-round           Check if a new round has started within the...
    competitions              Retrieves information about all competitions
    current-round             Get number of the current active round.
    daily-model-performances  Fetch daily performance of a model.
    download-dataset          Download specified file for the given round
    leaderboard               Get the leaderboard.
    list-datasets             List of available data files
    models                    Get map of account models!
    profile                   Fetch the public profile of a user.
    stake-decrease            Decrease your stake by `value` NMR.
    stake-drain               Completely remove your stake.
    stake-get                 Get stake value of a user.
    stake-increase            Increase your stake by `value` NMR.
    submission-filenames      Get filenames of your submissions
    submit                    Upload predictions from file.
    transactions              List all your deposits and withdrawals.
    version                   Installed numerapi version.

All CLI commands accept a --tournament option. It defaults to 8 (the classic tournament), but you can point the CLI at Signals (11) or Crypto (12) on a per-command basis, e.g. numerapi list-datasets --tournament 11.

Each command has it's own help page, for example:

$ numerapi submit --help
Usage: numerapi submit [OPTIONS] PATH

  Upload predictions from file.

Options:
  --tournament INTEGER  The ID of the tournament, defaults to 8
  --model_id TEXT       An account model UUID (required for accounts with
                        multiple models
  --help                Show this message and exit.
