import sensor, image, time

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.GRAYSCALE) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.B64X64) # or B40x30 or B64x64
clock = time.clock() # Tracks FPS.

old = sensor.snapshot()

while(True):
clock.tick() # Track elapsed milliseconds between snapshots().
img = sensor.snapshot()

[delta_x, delta_y, response] = old.find_displacement(img)   #这句报的错

old = img.copy()

print("%0.1f X\t%0.1f Y\t%0.2f QoR\t%0.2f FPS" %(delta_x, delta_y, response, clock.fps()))

find_displacement”object not iterable

IDE提示“find_displacement”object not iterable IDE版本1.90，固件版本1.93，主控是F765，使用光流例程的的时候IDE会报错，怎么解决 是对象不可迭代的意思吗？还是我没搞懂这个函数的用法
