pramiko .get 显示不一致的输出

Question

我正在使用以下代码通过 paramiko 在远程机器上运行命令。

commands = [[r"1st commands goes in here", "remote path", "localpath"],
[r"2nd commands goes in here", "remote path", "localpath"]]

for command in commands:
    # create a new session
    try:
        server = ShellHandler(ip_address, "admin", admin_pw)
        open_ftp = server.ftp()
    except:
        sys.exit("something went wrong, please try again")

    cmd = server.execute("cd /home/admin/automated")

    cmd = server.execute(command[0])

    open_ftp.get(command[1], command[2])

    # end the current session
    avamar.ssh.close()
    open_ftp.close()

我正在为每个命令创建一个新连接并将输出重定向到一个文件并使用 pramiko .get 下载该文件

我从这段代码中得到不一致的输出，有时它工作得很好并抓取文件，有时它会给出这个错误：

Traceback (most recent call last):
  File "Z:\gdrive\python\projects\automation\alpha\loop.py", line 726, in <module>

    raise IOError(errno.EACCES, text)
PermissionError: [Errno 13] Permission denied

知道这里出了什么问题吗！
