Parsing/Writing SysML v2? - python-3.x

Question

I'm trying to find an existing parser (preferably in Python) to write and read SysML v2.
The official Github repo by SysML v2 Submission Team (SST) has placed some examples online already (For instance https://github.com/Systems-Modeling/SysML-v2-Release/blob/master/sysml/src/examples/Vehicle%20Example/VehicleUsages.sysml ), but I'm unable to get the Eclipse Plugin running properly. (Nothing is shown in the preview windows, no error message either).
There's a repo for the SysML-v2-API-Python-Client which I installed and executed the given sample code (https://github.com/Systems-Modeling/SysML-v2-API-Python-Client), but all I'm getting is this message:
$ python3.8 Test1.py

Am I supposed to have anything running? Is there anywhere a tutorial or manual on how to use it?
Or are there any other parsers out there?

Answer 1

There are no parsers currently available for Python. The API Python Client is an example implementation to interact with the Pilot Server API Implementation. You would need to run the server to interact with the API using the python client.
