我试图将从摄像头读取的帧作为参数传递给另一个python脚本，但无法使其工作。
运行以下脚本每5秒在我的网络上存储一个摄像机帧：

#!/usr/bin/python

import cv2
import threading
import subprocess
import time
import datetime

def camera():
    camera = cv2.VideoCapture("/dev/video0")
    if not camera.isOpened():
        print("Cannot open camera.")
        raise SystemExit
    camera.set(cv2.CAP_PROP_FRAME_WIDTH, 320)
    camera.set(cv2.CAP_PROP_FRAME_HEIGHT, 320)
    camera.set(cv2.CAP_PROP_FPS, 15)
    return camera

try:
    camera = camera()
    while True:
        frame = camera.read()[1]
        #subprocess.call(["python", "/home/user/test2.py", frame])
        server = "/net/192.168.4.51/mnt/LAN4Storage/EC/Camera/"
        cv2.imwrite(server + "temp.jpg", frame)
        timestamp = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
        cv2.imwrite(server + timestamp + ".jpg", frame)
        time.sleep(5)

except Exception as error:
    print(error)

finally:
    camera.release()

如果我取消对subprocess.call行的注解，并对接下来的4行进行注解，我希望该帧传递给我的test2.py脚本：
`

#/usr/bin/env python

    import cv2
    import sys
    import os
    import time
    import datetime

    try:
        frame = cv2.imread(sys.argv[1])
        server = "/net/192.168.4.51/mnt/LAN4Storage/EC/Camera/"
        cv2.imwrite(server + "temp.jpg", frame)
        timestamp = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
        cv2.imwrite(server + timestamp + ".jpg", frame)

    except Exception as error:
        print(error)

    finally:
        pass

'但是在启动www.example.com时test1.py，我得到以下错误：

`expected str, bytes or os.PathLike object, not ndarray`
