Hi! Requesting for some help. Was running process_demo.py run - - with batch(chapter 4) and had an error: AWS Batch error: 2023-01-10 210726.950 [15/start/31 (pid 31166)] AWS Batch error: 2023-01-10 210726.950 [15/start/31 (pid 31166)] CannotPullContainerError: Error response from daemon: pull access denied for n/python, repository does not exist or may require 'docker login': denied: requested access to the resource is denied This could be a transient error.

Step failure: Step start (task-id 31) failed. When i made the configuration of CloudFormation template I set: apibasicauth:false Enable sagemaker: false Enable ui: false Where can the problem be? Thanks in advance!

can you paste the

process_demo.py

file? it seems that the flow is trying to use

n/python

image that doesn't exist.

Sure! from metaflow import FlowSpec, step import os global_value = 5 class ProcessDemoFlow(FlowSpec): @step def start(self): global global_value global_value = 9 print('process ID is', os.getpid()) print('global_value is', global_value) self.next(self.end) @step def end(self): print('process ID is' , os.getpid()) print('global_value is', global_value) if name == '__main__': ProcessDemoFlow()

and what does your metaflow config look like? If you peer into

~/.metaflowconfig/config.json

is there any value that's set to

n/python

?

There is a “metaflow_batch_container_registry” : ”n”. Should I change that? I cant see any configuration in aws outputs that resembles to that.

yeah - you can nuke that entire line

the flows should run without any issues after that

Thank you very much! That appears to solve the issue.
