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 and submission information. Some parts of the code were taken from numerflow by ChristianSch.
Visit his wiki, if you need further information on the reverse engineering process.

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

Layout

Parameters and return values are given with Python types. Dictionary keys are given in quotes; other names to the left of colons are for reference convenience only. In particular, lists of dicts have names for the dicts; these names will not show up in the actual data, only the actual dict data itself.

login

upload_predictions

Parameters

• file_path (str): path to CSV of predictions
  • should already contain the file name (e.g. "path/to/file/prediction.csv")

Return Values

• success: indicator of whether the upload succeeded

Notes

• Uploading a prediction shortly before a new dataset is released may result in a 400 Bad Request. If this happens, wait for the new dataset and attempt to upload again.
• Uploading too many predictions in a certain amount of time will result in a 429 Too Many Requests.
