When does this happen?
IF AsyncSqliteSaver raises AttributeError: 'Connection' object has no attribute 'is_alive' when using aiosqlite >= 0.22.0.
How others solved it
THEN Downgrade aiosqlite to version 0.21.0 (pip install aiosqlite==0.21.0) or apply a monkeypatch to add the missing is_alive method to aiosqlite.Connection before initializing the checkpointer. The monkeypatch defines a dummy is_alive that returns True.
import aiosqlite
def is_alive_patch(self):
return True
if not hasattr(aiosqlite.Connection, 'is_alive'):
setattr(aiosqlite.Connection, 'is_alive', is_alive_patch)Related patterns
