Romain Hardouin commented on CASSANDRA-13779:
---------------------------------------------
Hi, this error happens when there is a mismatch between Cassandra version and
Driver version. This is not related to PyCharm. Be sure to check [DataStax
driver compatibility
matrix|https://docs.datastax.com/en/developer/java-driver/3.3/manual/native_protocol/#compatibility-matrix].
(Note that DataStax Driver has its own bug tracker:
https://datastax-oss.atlassian.net/projects/JAVA/summary )
