How to use the openvino.tools.calibration.CommandLineProcessor.process function in openvino

def collect_statistics():
    with CommandLineProcessor.process() as configuration:
        calibrator = CalibratorFactory.create(configuration.precision, CalibratorConfiguration(configuration))

        print("Collecting FP32 statistics for {}...".format(configuration.model))
        fp32_result = calibrator.infer(add_outputs=True, collect_aggregated_statistics=True)
        print("FP32 accuracy: {0:.4f}{1}".format(fp32_result.metrics.accuracy.value, fp32_result.metrics.accuracy.symbol))

        output_model_file_path = Path.get_model(configuration.output_model, "_statistics")
        output_weights_file_path = Path.get_weights(configuration.output_weights, "_statistics")

        quantization_levels = calibrator.get_quantization_levels(CalibrationConfigurationHelper.read_ignore_layer_names(configuration))
        statistics = fp32_result.aggregated_statistics.get_node_statistics()
        calibrator.save(output_model_file_path, output_weights_file_path, quantization_levels, statistics)
        print("Network with statistics was written to {}.(xml|bin) IR file".format(os.path.splitext(output_model_file_path)[0]))
