SFTP:从远程服务器递归中复制/下载所有文件

Question

我得到了一个可以从远程目录下载到本地目录的代码，但是它给出了以下错误。

请解释错误的含义以及如何解决。它显示了第二行的问题。

我的代码

import paramiko, os
paramiko.util.log_to_file('/tmp/paramiko.log')
from stat import S_ISDIR
host = "ip"
port = 22
transport = paramiko.Transport((host, port))
password = "mypassword"
username = "username"
transport.connect(username = username, password = password)
sftp = paramiko.SFTPClient.from_transport(transport)
def sftp_walk(remotepath):
    path=remotepath
    files=[]
    folders=[]
    for f in sftp.listdir_attr(remotepath):
        if S_ISDIR(f.st_mode):
            folders.append(f.filename)
        else:
            files.append(f.filename)
    if files:
        yield path, files
    for folder in folders:
        new_path=os.path.join(remotepath,folder)
        for x in sftp_walk(new_path):
            yield x

for path,files  in sftp_walk("." or '/remotepath/'):
    for file in files:
        #sftp.get(remote, local) line for dowloading.
        sftp.get(os.path.join(os.path.join(path,file)), '/local path/')

错误我正在得到：
