_multiline_python_external

I am attempting to use a Python Module. In epy_module.xml the type is _multiline_python_external.

 

When I attempt to use this module in a flowgraph, I get an error that the type "is not a possible type".

 

However, I have seen this type used successfully in Version 3.7.9 for Windows.

 

I am using version 3.7.5 on a Raspberry Pi.

 

What do I need to do to use this type in a module?
