编译器向我显示此错误：struct.error：ushort format需要0＆lt; = number＆lt; = USHRT_MAX

Question

client.py

import cv2
import numpy as np
import socket
import sys
import pickle
import struct 
cap=cv2.VideoCapture(0)
clientsocket=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
clientsocket.connect(('localhost',5000))
while True:
    ret,frame=cap.read()
    data = pickle.dumps(frame) 
    clientsocket.sendall(struct.pack("H", len(data))+data)

错误在最后一行。

  

错误：struct.error：ushort格式要求0＆lt; = number＆lt; = USHRT_MAX。

Answer 1

修改＆＃34; H＆＃34;用＆＃34; L＆＃34;在客户端和服务器上。应该工作
