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.
This has been fixed in Paramiko 2.5.0 already:
https://www.paramiko.org/changelog.html#2.5.0
https://github.com/paramiko/paramiko/pull/1379
https://github.com/paramiko/paramiko/issues/1369
I've had better success with:
import warnings
warnings.simplefilter("ignore", cryptography.utils.DeprecatedIn23)
