我正在尝试运行我的 python 代码，但第二个函数（见下文.. md5()）不起作用！这是我需要解决的错误吗？

**连接到设备” 10.0.100.126 您要上传哪个图像？是的，您想为图像命名什么？测试按 Enter 继续目标文件名 [测试]？上传............ …………………………………………………………………………………………

from netmiko import ConnectHandler

from keyboard import press

from pynput.keyboard import Key, Controller

from test import image_name

with open('dev_devices.txt') as f:
    devices_list = f.read().splitlines()

for ip_address in devices_list:
    print('___________________________________________________________\n')
    print('Connecting to device" ' + ip_address)
    ios_device = {
        'device_type': 'cisco_ios',
        'ip': ip_address,
        'global_delay_factor': 4,
        "fast_cli": False,

    }

ios_device.update(yml('pass.yml', 'admin_a'))

cmd = "copy tftp://10.36.50.60/s2t54-ipservicesk9-mz.SPA.152-1.SY6.bin bootdisk:/"


def upload():
    net_connect = ConnectHandler(**ios_device)
    net_connect.enable()
    firmware = input("which image would you like to upload?")
    if firmware == "yes":
        name = input("what would you like to name the image?")
        output = net_connect.send_command(cmd + name, delay_factor=4, expect_string=r'Destination filename')
        input("press enter to continue")
        press('enter')
        print(output)
        print("UPLOADING.....................................")
        net_connect.send_command("wr")
        net_connect.disconnect()


upload()

time.sleep(20)


def md5(): # This function does not run for some reason, I have no idea
    net_connect = ConnectHandler(**ios_device)
    net_connect.enable()
    name = input("which image would you like to compare?")
    checksum = net_connect.send_command("verify /md5 bootdisk:" + name, delay_factor=4)
    print(checksum[-31:])
    net_connect.disconnect()



md5()

错误如下

您的异常堆栈跟踪表明您wr在上传功能中执行失败。

  File "C:\Users\rashhad.miah\Desktop\netauto\test.py", line 37, in upload
    net_connect.send_command("wr")

你还需要那个吗？

特别是它在该wr命令的回显上失败了，即 Netmiko 期望wr得到回显，但它从未见过它：

packages\netmiko\base_connection.py", line 1490, in send_command
    new_data = self.read_until_pattern(pattern=re.escape(cmd))

您可能想查看 Netmiko session_log 或 Netmiko 的调试日志
