Sqlite3 error while exporting HB model to OSM

Hello everyone,

I am facing an error when I export my HB model to OSM for simulation :
The eplusout.err file shows :
** Fatal ** The SQLite database failed to open.
and the sqlite.err shows :
SQLite3 message, sqlite.err open for processing!
SQLite3 message, can’t get exclusive lock on existing database: bad parameter or other API misuse

I temporarily solved the problem removing this line from idf file :
Output:SQLite,
SimpleAndTabular; !- Option Type
But I would like to found a long-term solution.
I think the problem started after installing python3 in my compute last week. Anyone has a idea how to solve it?

Thank you

Hey @FabienR ,

You usually get this error when you have the EnergyPlus SQLite file open in another program while trying to rerun EnergyPlus in a manner that overwrites the file. Try seeing if the eplusout.sql file is open in another program or see if you can delete it manually before simulating.

I doubt the problem has anything to do with your python3 installation.
