Paramiko /加密技术弃用警告：CryptographyDeprecationWarning：EllipticCurvePublicNumbers弃用了encode_point

问题描述

在进行简单的SSH连接时，我不断收到以下弃用警告：

I keep getting the following deprecation warnings when doing simple SSH connections:

2019-03-04 02:21:14 [transport] INFO : Connected (version 2.0, client OpenSSH_7.4)
/usr/local/lib/python2.7/site-packages/paramiko/kex_ecdh_nist.py:39: 
  CryptographyDeprecationWarning: encode_point has been deprecated 
  on EllipticCurvePublicNumbers and will be removed in a future 
  version. Please use EllipticCurvePublicKey.public_bytes to obtain 
  both compressed and uncompressed point encoding.
m.add_string(self.Q_C.public_numbers().encode_point())
/usr/local/lib/python2.7/site-packages/paramiko/kex_ecdh_nist.py:96: 
  CryptographyDeprecationWarning: Support for unsafe construction of 
  public numbers from encoded data will be removed in a future version. 
  Please use EllipticCurvePublicKey.from_encoded_point
  self.curve, Q_S_bytes
/usr/local/lib/python2.7/site-packages/paramiko/kex_ecdh_nist.py:111: 
CryptographyDeprecationWarning: encode_point has been deprecated on 
   EllipticCurvePublicNumbers and will be removed in a future version. 
   Please use EllipticCurvePublicKey.public_bytes to obtain both

hm.add_string(self.Q_C.public_numbers().encode_point())
2019-03-04 02:21:14 [transport] INFO : 
   Authentication (keyboard-interactive) successful!

随着程序成功运行，更多的烦恼是如何摆脱这些烦恼消息？

This more of an annoyance, as the program runs successfully, any ideas on how to get rid of these messages?

我正在将Paramiko 2.4.2与Python 2.7.9一起使用
