NameError: name 'CallPipeline' is not defined

When I run Video_Lane_detecct.py, I meet this problem. But I have imported pipeline.py. I do not know what i should input here.
video_output1 = 'test1.MOV'
video_input1 = VideoFileClip('project_video.mp4')#.subclip(20,25)
processed_video = video_input1.fl_image(CallPipeline)
print("1")
processed_video.write_videofile(video_output1, audio=False)
print("done")
video_input1.reader.close()
video_input1.audio.reader.close_proc()
And the problem shows that:
