specific project.
Authorize user, sets value of global variable ``project`` to :class:`~neptune.projects.Project` object
that can be used to create or list experiments, notebooks, etc.
Args:
project_qualified_name (:obj:`str`, optional, default is ``None``):
Qualified name of a project in a form of ``namespace/project_name``.
If ``None``, the value of ``NEPTUNE_PROJECT`` environment variable will be taken.
api_token (:obj:`str`, optional, default is ``None``):
User's API token. If ``None``, the value of ``NEPTUNE_API_TOKEN`` environment variable will be taken.
.. note::
It is strongly recommended to use ``NEPTUNE_API_TOKEN`` environment variable rather than
placing your API token in plain text in your source code.
proxies (:obj:`dict`, optional, default is ``None``):
Argument passed to HTTP calls made via the `Requests <https://2.python-requests.org/en/master/>`_ library.
For more information see their proxies
`section <https://2.python-requests.org/en/master/user/advanced/#proxies>`_.
.. note::
Only `http` and `https` keys are supported by all features.
.. deprecated :: 0.4.4
Instead, use:
.. code :: python3
from neptune import HostedNeptuneBackendApiClient
neptune.init(backend=HostedNeptuneBackendApiClient(proxies=...))
backend (:class:`~neptune.ApiClient`, optional, default is ``None``):
By default, Neptune client library sends logs, metrics, images, etc to Neptune servers:
either publicly available SaaS, or an on-premises installation.
You can also pass the default backend instance explicitly to specify its parameters:
.. code :: python3
from neptune import HostedNeptuneBackendApiClient
neptune.init(backend=HostedNeptuneBackendApiClient(...))
Passing an instance of :class:`~neptune.OfflineApiClient` makes your code run without communicating
with Neptune servers.
.. code :: python3
from neptune import OfflineApiClient
neptune.init(backend=OfflineApiClient())
.. note::
Instead of passing a ``neptune.OfflineApiClient`` instance as ``backend``, you can set an
environment variable ``NEPTUNE_BACKEND=offline`` to override the default behaviour.
Returns:
:class:`~neptune.projects.Project` object that is used to create or list experiments, notebooks, etc.
Raises:
`NeptuneMissingApiTokenException`: When ``api_token`` is None
and ``NEPTUNE_API_TOKEN`` environment variable was not set.
`NeptuneMissingProjectQualifiedNameException`: When ``project_qualified_name`` is None
and ``NEPTUNE_PROJECT`` environment variable was not set.
`InvalidApiKey`: When given ``api_token`` is malformed.
`Unauthorized`: When given ``api_token`` is invalid.
Examples:
.. code:: python3
# minimal invoke
neptune.init()
# specifying project name
neptune.init('jack/sandbox')
# running offline
neptune.init(backend=neptune.OfflineApiClient())
