Error when running mesa_example: sqlite3.ProgrammingError: SQLite objects created in a thread can only be used in that same thread.

Hi, I'm trying to run mesa_example/start.py but get this error regardless of how I run it (either through Pycharm or command prompt):

Traceback (most recent call last): File "C:\Users\Andrew\PycharmProjects\abce\venv\Lib\site-packages\sqlalchemy\pool\base.py", line 377, in _close_connection self._dialect.do_terminate(connection) File "C:\Users\Andrew\PycharmProjects\abce\venv\Lib\site-packages\sqlalchemy\engine\default.py", line 698, in do_terminate self.do_close(dbapi_connection) File "C:\Users\Andrew\PycharmProjects\abce\venv\Lib\site-packages\sqlalchemy\engine\default.py", line 701, in do_close dbapi_connection.close() sqlite3.ProgrammingError: SQLite objects created in a thread can only be used in that same thread. The object was created in thread id 16296 and this is thread id 26788.

Any ideas?

I don't have access to a Windows machine to be able to debug. That Mesa example already uses Mesa's data collector. What about commenting out all the lines containing self._db in https://github.com/AB-CE/abce/blob/master/abcEconomics/__init__.py, and install from the repo pip install .?

That Mesa example already uses Mesa's data collector.

As such, it is redundant with abcEconomics' data collector.
