Yup! Have two queues: services with one worker spun up in --services-mode , and another queue (say foo ) that has a bunch of GPU workers on them. When I start the pipeline locally, jobs get sent off to foo and executed exactly how I'd expect. If I keep everything exactly the same, and just change pipeline.start_locally() -> pipeline.start() , the pipeline task itself is picked up by the worker in the services queue, sets up the venv correctly, prints Starting Task Execution: then does nothing 😕
