Dynamic Inventory on VMWare not working; but works when the script is run directly

[computerp...@gmail.com]

I am trying to implement  Dynamic Inventory for VMWare with the vmware_inventory.py script 

From here :

https://github.com/ansible/ansible/blob/devel/contrib/inventory/vmware_inventory.py

I have searched for docs on the ansible site and also google searched and there is nothing useful.

the script vmware_inventory.py works and produces a list of VMs when run directly 

# . python2 vmware_inventory.py 

But when i try this 

ansible -i vmware_inventory.py all -m shell -a "cat /etc/redhat-release"

nothing happens

This is from my ansible.cfg

[inventory]

enable_plugins = vmware_vm_inventory, host_list, script, yaml, ini, auto

I created a vmware.yml file in /etc/ansible but no luck.  There are no details as to what is required to get this working

https://docs.ansible.com/ansible/latest/plugins/inventory/vmware_vm_inventory.html

vmware.yml
