By default, toggles the extension in the system-wide Jupyter configuration location (e.g. /usr/local/etc/jupyter). Parameters ---------- import_name : str Importable Python module (dotted-notation) exposing the magic-named `load_jupyter_server_extension` function enabled : bool [default: None] Toggle state for the extension. Set to None to toggle, True to enable, and False to disable the extension. parent : Configurable [default: None] user : bool [default: True] Toggle in the user's configuration location (e.g. ~/.jupyter). sys_prefix : bool [default: False] Toggle in the current Python environment's configuration location (e.g. ~/.envs/my-env/etc/jupyter).
