直线检测报错，求教！

请问这是什么错误呀

import sensor, image, time

sensor.reset()

sensor.skip_frames(time = 1000)

    #time.sleep(3000)

        img_op.draw_line(l.line(), color = (255, 0, 0))

        print(l.theta())



sensor.flush()

31行没有冒号，而且不应该有空行

嗯嗯 刚才忘了加冒号。。。改过之后变成这样了，说帧缓存区空间不够？这是怎么回事啊

import sensor, image, time

sensor.reset()
sensor.set_framesize(sensor.QVGA)

新的问题，新的报错提示，请单独发帖子

这行代码前面有未识别的字符，在IDE里面把前面的空格全部删掉，在上一行代码结尾回车换行，对齐后重新编译。
