Hi, we're running into an issue (stack trace below) in Owlready2 (v0.36) when used in a system with sqlite3 v3.7.17, and when input ontologies are rather large — in general, functions are very slow. Using a newer version of sqlite3 this error doesn't seem occur and the package seems performant (e.g., in my local environment I've got sqlite3 v3.36.0 and I don't get the same slowness and error).
Is there a minimum version of sqlite3 that you recommend be installed for optimal performance of owlready2?
Thank you.
