U盘自动弹出导致连接断开，不产生数据，是为什么？

[a2ds]

使用edge impluse训练模型产生的.py文件在IDE中运行，当识别到数据时U盘自动弹出导致连接断开，不产生数据，是为什么？
代码正常，当摄像头拍摄别的物体时，正常传输概率数据，当拍摄并识别到我的人脸时，就自动断开连接。

# Edge Impulse - OpenMV Image Classification Example

import sensor, image, time, os, tf

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)          # Let the camera adjust.

net = "trained.tflite"
labels = [line.rstrip('\n') for line in open("labels.txt")]

clock = time.clock()
while(True):
    clock.tick()

    img = sensor.snapshot()

    # default settings just do one detection... change them to search the image...
    for obj in tf.classify(net, img, min_scale=1.0, scale_mul=0.8, x_overlap=0.5, y_overlap=0.5):
        print("**********\nPredictions at [x=%d,y=%d,w=%d,h=%d]" % obj.rect())
        img.draw_rectangle(obj.rect())
        # This combines the labels and confidence values into a list of tuples
        predictions_list = list(zip(labels, obj.output()))

        for i in range(len(predictions_list)):
            print("%s = %f" % (predictions_list[i][0], predictions_list[i][1]))

    print(clock.fps(), "fps")

固件版本是多少？硬件用的是什么？

[a2ds]

固件版本4.0.2（最新），硬件OPENMV4PLUS

[a2ds]

使用OPENMV3代入例程正常，使用4PLUS代入例程以及之前写的程序也正常，是否是因为此代码运算量过大或其他原因导致IDE bug？
