    Performance profiling API.

    This API enables MindSpore users to profile the performance of neural network.
    Profiler supports Ascend and GPU, both of them are used in the same way,
    but only output_path in args works on GPU. And it can only be initialized once.

    Args:
        output_path (str): Output data path.
        optypes_not_deal (str): (Ascend only) Op type names, determine the data of which optype should be collected
            and analysed, will deal with all op if null. Different op types should be separated by comma.
        ascend_job_id (str): (Ascend only) The directory where the profiling files to be parsed are located.
            This parameter is used to support offline parsing.
        profile_communication (bool): Whether to collect communication performance data in a multi devices training,
            collect when True. Default is False. Setting this parameter has no effect during single device training.
        profile_memory (bool): Whether to collect tensor memory data, collect when True. Default is False.
        start_profile (bool): The start_profile parameter controls whether to enable or disable performance data
            collection based on conditions. The default value is True.

    Examples:
