Custom authentication

The TrainingSetClient is a Python module wrapping a set of API methods. See Authentication for the default behavior of the TrainingSetClient. To override authentication, you need to set the right environment variable with your own user API key:

import os

os.environ["DOMINO_USER_API_KEY"] = "<your-own-api-key>"

# In Domino endpoint if the client version is <0.1.8
os.environ["DOMINO_API_HOST"] = os.getenv("DOMINO_USER_HOST")

export DOMINO_USER_API_KEY=<your-own-api-key>

# In Domino endpoint if the client version is <0.1.8
export DOMINO_API_HOST=$DOMINO_USER_HOST
