Ansible with vmware, PyVmomi needs to be installed on ESX?

Is it mandatory to install PyVmomi on Esx to talk with ansible.

http://docs.ansible.com/ansible/latest/vmware_vmkernel_module.html#id2.

Not able to install get-pip or PyVmomi from EsxCLi.

Not on the ESX, in the documentation is says "Requirements (on host that executes module)"

By that it means the control machine aka. the machine runnning ansible/ansible-playbook command.

Thanks Kai for the clarification. It was useful.
