To visualize the predicted result in jupyter notebook, it might be better to obtain the visualization result by

visualizer.add_datasample(
    'result',
    img,
    data_sample=data_samples,
    ...
    show=False,
    out_file=None)
img_vis = visualizer.get_image()

and then plot img_vis with cv2_imshow or matplotlib.pyplot.
In this way, the read/write processes of images can be avoided.
