kfctl.sh apply platform assumes availability of yaml python library

[cwbeitel]

> ${KUBEFLOW_REPO}/scripts/kfctl.sh apply platform
...
Traceback (most recent call last):
  File "/Users/cb/deploy/kfctl/scripts/gke/iam_patch.py", line 17, in <module>
    import yaml
ImportError: No module named yaml

This was after running download.sh without setting KUBEFLOW_VERSION i.e. pulling from master.

I ran into this as well. i tried pip install PyYAML as a way around it

If you're on gcp you can run

pip install pyyaml --user

I think the long term fix here is to replace kfctl.sh with a go binary #1419.
