我尝试了这样output = obj.output()[:3]，无变化
又尝试了a=output【0】 b=a【：5】 img.draw_string(10,110, str(b))显示错误

import sensor, image, time, tf,lcd 

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.set_windowing((240, 240))       # Set 240x240 window.
sensor.skip_frames(time=2000)   
lcd.init()       # Let the camera adjust.


mobilenet = "openmv_classify.tflite"
labels = [line.rstrip() for line in open("labels.txt")]
class_num = len(labels)

clock = time.clock()
while(True):
    clock.tick()
    img = sensor.snapshot()
    for obj in tf.classify(mobilenet, img, min_scale=1.0, scale_mul=0.8, x_overlap=0.5, y_overlap=0.5):
        img.draw_rectangle(obj.rect())
        output = obj.output()
        
        for i in range(class_num):
            print("%s = %f" % (labels[i], output[i]))
    print(clock.fps(), "fps")

    img.draw_string(10,110, str(output))              # 文字输入 固定
    img.draw_string(10,100, "no mask            msak")
    
    lcd.display(img)

比如口罩检测中的mask=0.9显示在lcd屏上

@kidswong999 请问openmv连接电脑后闪几下绿灯后断开连接怎么解，已更换电脑测试，还这样
