Re: [sqlalchemy] AssertionError: Type class 'sqlalchemy.engine.interfaces.Connectable' is already registered
that looks pretty much like modules are being reloaded in process. Either get web.py to not reload the sqlalchemy modules, or if it has to, then get it to fully load sqlalchemy completely. I see that reload(mod) right in the stack trace there. On 6/26/14, 1:14 PM, Dustin Oprea wrote: I'm using SQLAlchemy with web.py, and have used it many times in the past.
