=========================================


.. py:class:: ansys.lumerical.mcp.persistent_session.LumericalPersistentPythonSession(python_executable: Optional[str] = None, startup_code: Optional[str] = None, working_directory: Optional[str] = None)

   Bases: :py:obj:`ansys.common.mcp.helpers.PersistentPythonSession`


   
   A :class:`PersistentPythonSession` that tolerates long, silent operations.

   :meth:`execute` blocks indefinitely on a per-call completion marker; hung
   calls are recovered out-of-band by the ``restart_session`` MCP tool, which
   invokes :meth:`PersistentPythonSession.restart`.
