Python Paramiko错误

我写了一个python程序。我有conf文件，我在conf文件中编写了路由器配置命令，我想在paramiko中执行这些命令。我有一个问题-错误消息如下。你能帮我吗？ 代码：

错误消息：

尝试使用以下代码：

import paramiko

if __name__ == "__main__":
    ip = "127.0.0.1"
    username = "admin"
    password = "root"

    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(ip,username=username,password=password)
    ssh_transport = ssh.get_transport()

    for command in ("ls /tmp", "date"):
        chan = ssh_transport.open_session()
        chan.exec_command(command)
        exit_code = chan.recv_exit_status()
        stdin = chan.makefile('wb', -1)         # pylint: disable-msg=W0612
        stdout = chan.makefile('rb', -1)
        stderr = chan.makefile_stderr('rb', -1)  # pylint: disable-msg=W0612
        output = stdout.read()
        print output

尝试以下代码，首先将conf文件复制到远程服务器并执行该文件

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
host = str(host)
user = 'root'
pw = 'root123'
ssh.connect(host, username=user, password=pw)

filepath = "conf"
remote_path = "/root/qats_tool.tar"

sftp = ssh.open_sftp()
sftp.put(filepath, remote_path)

command="./conf"
stdin, stdout, stderr = ssh.exec_command(command)
sftp.close()

import paramiko

if __name__ == "__main__":
    ip = "127.0.0.1"
    username = "admin"
    password = "root"

    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(ip,username=username,password=password)
    ssh_transport = ssh.get_transport()

    for command in ("ls /tmp", "date"):
        chan = ssh_transport.open_session()
        chan.exec_command(command)
        exit_code = chan.recv_exit_status()
        stdin = chan.makefile('wb', -1)         # pylint: disable-msg=W0612
        stdout = chan.makefile('rb', -1)
        stderr = chan.makefile_stderr('rb', -1)  # pylint: disable-msg=W0612
        output = stdout.read()
        print output

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
host = str(host)
user = 'root'
pw = 'root123'
ssh.connect(host, username=user, password=pw)

filepath = "conf"
remote_path = "/root/qats_tool.tar"

sftp = ssh.open_sftp()
sftp.put(filepath, remote_path)

command="./conf"
stdin, stdout, stderr = ssh.exec_command(command)
sftp.close()
