    Please use the python_capi converter cython module, imported like:
        from cimport <py3_namespace>.<module_name>.thrift_converter cimport (
            <TypePythonName>_convert_to_cpp,
            <TypePythonName>_from_cpp,
        )
    Using the converter module requires only a single import cython dep:
        "//path/to/package:<thrift_module_name>-python_capi-types-converter"
