在进行简单的 SSH 连接时，我不断收到以下弃用警告:

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:

  on EllipticCurvePublicNumbers and will be removed in a future 
  version. Please use EllipticCurvePublicKey.public_bytes to obtain 
  both compressed and uncompressed point encoding.

这更令人烦恼，因为程序成功运行，关于如何摆脱这些消息的任何想法？

我正在使用 Paramiko 2.4.2 和 Python 2.7.9
