Module Contents

.. py:class:: RUN_VALIDATOR(validate_task_name=AppConstants.TASK_VALIDATION, project_id='', query='')

   Bases: :py:obj:`nvflare.apis.executor.Executor`


   Wrapper executor that runs user-provided FLIP_VALIDATOR implementations.

   This executor handles:
   - Dynamic importing of the user's FLIP_VALIDATOR class
   - Error handling and exception logging
   - Lazy initialization of the validator instance

   Initialize the RUN_VALIDATOR executor.

   :param validate_task_name: Task name for validation task. Defaults to "validate".
   :param project_id: The ID of the project the model belongs to.
   :param query: The cohort query that is associated with the project.


   .. py:method:: execute(task_name: str, shareable: nvflare.apis.shareable.Shareable, fl_ctx: nvflare.apis.fl_context.FLContext, abort_signal: nvflare.apis.signal.Signal) -> nvflare.apis.shareable.Shareable

      Execute the validation task.

      This method:
      1. Lazily imports and initializes the user's FLIP_VALIDATOR
      2. Delegates execution to the user's validator
      3. Catches and reports any exceptions

      :param task_name: The name of the task to execute
      :param shareable: The input shareable data
      :param fl_ctx: The FL context
      :param abort_signal: Signal for aborting the task

      :returns: *Shareable* -- The result of the validation task
