initialize(*args, api_token=None, verbose=False, proxies=None, **kwargs) #

Initialize a client session.

A session has a global scope and remains active until interpreter shutdown.

Retrieve an API token from the Developer page and make it available through one of the following options before initializing:

  1. Directly through the api_token keyword argument 
    import kolena

kolena.initialize(api_token=your_token, verbose=True)
  2. Populate the KOLENA_TOKEN environment variable 
    export KOLENA_TOKEN="********"
  3. Store in .netrc file
    ~/.netrc
    machine api.kolena.io password ********

Note

As of version 0.29.0: the entity argument is no longer needed; the signature initialize(entity, api_token) has been deprecated and replaced by initialize(api_token).

Parameters:

Name Type Description Default
api_token Optional[str]

Optionally provide an API token, otherwise attempts to find a token in $KOLENA_TOKEN or .netrc file. This token is a secret and should be treated with caution.

 False
proxies Optional[Dict[str, str]]

Optionally configure client to run with http or https proxies. The proxies parameter is passed through to the requests package and can be configured accordingly.

 None

Raises:

Type Description
InvalidTokenError

The provided api_token is not valid.
InputValidationError

The provided combination or number of args is not valid.
MissingTokenError

An API token could not be found.
