 [701] SIMULATION_MISSING_EXTRA
################################

*************
 Description
*************

Extra dependencies required for simulation are missing.

****************
 How to Resolve
****************

To use simulation with the Ray backend, add ``flwr`` with the ``simulation`` extra to
the app's ``pyproject.toml`` dependencies:

.. code-block:: toml

    dependencies = [
        "flwr[simulation]",
    ]

Then install the app dependencies manually unless automatic runtime dependency
installation is enabled, and retry.
