How to use the miscnn.data_loading.interfaces.Image_interface function in miscnn

def test_IOI_IMAGE_creation(self):
        interface = Image_interface()
    # Initialization

        seg = interface.load_segmentation(sample_list[0])
        self.assertTrue(np.array_equal(img, self.img[:,:,0]))
        self.assertTrue(np.array_equal(seg, self.seg[:,:,0]))
    # NIFTI_interface - Loading and Storage of Predictions

        self.assertEqual(len(sample_list), 1)
        self.assertEqual(sample_list[0], "image")
