怎么helloworld也不行呀？显示Sensor Timeout？

# Hello World Example
#
# Welcome to the OpenMV IDE! Click on the green run arrow button below to run the script!

import sensor, image, time

sensor.reset()                      # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA)   # Set frame size to QVGA (320x240)
sensor.skip_frames(time = 2000)     # Wait for settings take effect.
clock = time.clock()                # Create a clock object to track the FPS.

while(True):
    clock.tick()                    # Update the FPS clock.
    img = sensor.snapshot()         # Take a picture and return the image.
    print(clock.fps())              # Note: OpenMV Cam runs about half as fast when connected
                                    # to the IDE. The FPS should increase once disconnected.

RuntimeError：Sensor Timeout
之前还可以显示的，不知道是不是动了什么东西，就突然timeout了 而且连接的时候闪了3下红灯

看一下sensor模组是不是松了？

请问怎样检查sensor模组呢？

把sensor模组旁边的螺丝拧好。
