我正在做一个网络配置项目。我想在 cisco nexus 交换机上启用密码加密以进行密码加密。我需要在命令执行后处理提示，这是我的 python 代码：

def audit_password_encryption():

 pass_encryption = False
 output = net_connect.send_command('show encryption service stat')
 if(str.__contains__(output,"not being used")):
    a = input("Şifreler clear-text formatında tutuluyor. AES şifrelemeyi konfigüre etmek ister misiniz? EVET[1] HAYIR[2]")
    if a==str(1):
         do_password_encryption()

def do_password_encryption():

 passw = input("16-64 karakter sayisinda bir master key girin : ")
 

 output=net_connect.send_command(
     command_string='key config-key ascii',
     expect_string=r"New Master Key:",
     strip_prompt=False,
     strip_command=False
 )
 output += net_connect.send_command(
     command_string=passw+"\n",
     expect_string=r"Retype Master Key:",
     strip_prompt=False,
     strip_command=False
 )
 output += net_connect.send_command(
     command_string=passw+"\n",
     expect_string=r"#",
     strip_prompt=False,
     strip_command=False
 )

 config_commands = ['feature password encryption aes']
 net_connect.send_config_set(config_commands)

执行后出现如下错误：

File "/usr/local/lib/python3.8/dist-packages/paramiko/channel.py", line 699, in recv
 out = self.in_buffer.read(nbytes, self.timeout)
File "/usr/local/lib/python3.8/dist-packages/paramiko/buffered_pipe.py", line 164, in read
 raise PipeTimeout()
paramiko.buffered_pipe.PipeTimeout

During handling of the above exception, another exception occurred:

为什么我会收到此错误？或者你有什么想法在命令执行后处理提示？谢谢
