change_detector.py(103)_get_test_inputs()：

    def _get_test_inputs(self, image_shape):
        if image_shape is not None:
            if len(image_shape) == 2:
                image_shape = [1, 3] + image_shape
            self._fix_transforms_shape(image_shape[-2:])
        else:
            image_shape = [None, 3, -1, -1]
        self.fixed_input_shape = image_shape
        return [
            InputSpec(
                shape=image_shape, name='image', dtype='float32'), InputSpec(
                    shape=image_shape, name='image2', dtype='float32')
        ]

这里返回的一个list，export模型时：

ValueError(error_msg) ValueError: The decorated function forwardrequires 1 arguments: ['x'], but received 2 with (InputSpec(shape=(-1, 3, 256, 256), dtype=paddle.float32, name=image), InputSpec(shape=(-1, 3, 256, 256), dtype=paddle.float32, name=image2))
