That error message was improved/fixed in cx_Oracle 7.1. What it's saying is that your PATH (on Windows) or LD_LIBRARY_PATH (on Linux or Unix) has an old version of Oracle Client libraries. You need to install newer ones somewhere and set PATH or LD_LIBRARY_PATH to them before you run Python. Newer Oracle client libraries will still allow you to connect to older databases (but not really old ones). Check the cx_Oracle installation instructions https://cx-oracle.readthedocs.io/en/latest/installation.html

Which of the two errors? What operating system? What version of cx_Oracle? What other Oracle software have you got installed?

Start with https://cx-oracle.readthedocs.io/en/latest/user_guide/installation.html#troubleshooting and post much more detail if you still have problems
