I was trying to reproduce with 2 0b7 but it worked just fine ```from prefect import flow task from prefect import get run logger from prefect task runners import DaskTaskRunner from prefect flow runners import DockerFlowRunner from prefect deployments import DeploymentSpec import time task def compute something x logger = get run logger <http logger info|logger info> Computing d x 2 = d x x 2 time sleep 2 flow task runner=DaskTaskRunner def dask flow for i in range 50 compute something i DeploymentSpec name= staging flow=dask flow flow runner=DockerFlowRunner ```

< Anna Geller> 2 0b6 I figured it out I was calling the for loop outside the flow task runner=DaskTaskRunner ``` task def compute something x logger = get run logger Computing d x 2 = d x x 2 time sleep 2 flow task runner=DaskTaskRunner def dask flow list map compute something range 50 worked if name == main list map dask flow range 50 didn t work dask flow DeploymentSpec name= staging flow=dask flow flow runner=DockerFlowRunner ```
