OK, yeah this line: https://github.com/operator/sqlalchemy_bulk_lazy_loader/blob/master/lib/sqlalchemy_bulk_lazy_loader.py#L141 should be removed and a simple "from sqlalchemy.orm import strategy_options" should be placed at the top of the module. otherwise, this line is adding a "dependency" to the "importlater" thing (which is something that resolves import cycles in SQLAlchemy in a thread-safe way) that isn't getting resolved. > > The error seem to happen even without using the custom 'bulk' lazy option on > any relation, as long as BulkLazyLoader.register_loader()runs. > > I'll take this issue to bulk lazy loader, since the origin of this error is > probably there. > > Thanks for all your effort trying to help me! > > /Hugo > > On Tue, Nov 7, 2017 at 6:41 PM, Mike Bayer <mike...@zzzcomputing.com> wrote: >> >> Are you able to reproduce this error in other environments or only this >> one particular virtual environment?
