pip install mysql-connector-python works just fine

This seems to be Connector/C related. How did you build/install MariaDB Connector/C ?

Comment by Stanislav Seltser [ 2020-02-24 ]

Brew install mariadb

Comment by Georg Richter [ 2020-02-24 ]

Did you also install libiconv (homebrew). ?
It looks like the build process links against the system libiconv, which has different symbols.
Usually brew install libiconv will report LDFLAGS which you need to set before installing MariaDB Connector/Python.

This issue was fixed in Connector/C version 3.1.10: The default lib will not use iconv anymore.
