It seems cause by no kubernetes provider ?

You need to run pulumi programs via the pulumi cli, not via python directly. Put that code:
import pulumi
import pulumi_kubernetes as k8s

guestbook = k8s.yaml.ConfigFile('guestbook', 'guestbook-all-in-one.yaml')
in it's own .py file and add a
file like:
name: k8s
runtime: python
and then run
pulumi up
in that directory.
