Get Error from server (NotFound): pods "Error" not found

[aginpatrick]

Followed all your steps (apparently without errors). At step 4 (./4_start_ui.sh), I get the following :

 `error: error executing jsonpath "{.items[0].metadata.name}": array index out of bounds: index 0, length 0`
`Error from server (NotFound): pods "Error" not found`

It seems that the kubeflow namespace does not exist:

`kubectl get pods -n kubeflow` gives:
`No resources found.`

`kubectl get pods --all-namespaces` gives:

Any help someone? What step is supposed to create the kubeflow namespace?
thanks
