Skipping plugin

Hello Team,

Am getting below warning message while running ansible Ad hoc command. There is no changes made in ansible.cfg file. How to avoid the below warning message. Could you please some one help me on this.

The issue is fixed by myself. One of the recent package install via pip was causing the issue. After removing that package issue got fixed.
