How to deal with the CryptographyDeprecationWarning in python fabric?

c:\users\administrator\.virtualenvs\spiderworker-dgts38t8\lib\site-packages\paramiko\kex_ecdh_nist.py:39: CryptographyDeprecationWarning: encode_point has been deprecated on EllipticCurvePublicNumbers and will be removed in a fut
ure version. Please use EllipticCurvePublicKey.public_bytes to obtain both compressed and uncompressed point encoding.
  m.add_string(self.Q_C.public_numbers().encode_point())
c:\users\administrator\.virtualenvs\spiderworker-dgts38t8\lib\site-packages\paramiko\kex_ecdh_nist.py:96: CryptographyDeprecationWarning: Support for unsafe construction of public numbers from encoded data will be removed in a fu
ture version. Please use EllipticCurvePublicKey.from_encoded_point
  self.curve, Q_S_bytes

  hm.add_string(self.Q_C.public_numbers().encode_point())

finding the keywork in the source code, you will see class CryptographyDeprecationWarning. invoked by function _verify_openssl_version.

"OpenSSL version 1.0.1 is no longer supported by the OpenSSL "
            "project, please upgrade. A future version of cryptography will "
