ansible-control-host

  config file = /home/user/ansible_training/ansible.cfg
  configured module search path = ['/home/user/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']

Stop right there. That "ansible" is from well before it was split to
ansible-core, which has the ansible scripts and binaries, and is now
up to version 2.13 in RPMs available for RHEL and CentOS 8. And the
"ansible" package, itself, is no longer ansible. It's a collection of
more than 100 "ansible_collections" modules, in a tarball called
"ansible", and yes it is amazingly confusing.

Don't install the "ansible" package anymore on RHEL. There is no
official RPM published for it from Red Hat, there is only the
"ansible-core" package. The only one who publishes a workable RPM, or
RPM building tools for it on RHEL, is me over at
https://github.com/nkadel/ansiblerepo/.

To get the right tool via RPM, use this.

     sudo dnf remove ansible
     sudo dnf install ansible-core

This should help. The split of python to "python2" and "python3"
caused a lot of confusion, and I'm afraid that older versions of
ansible are not as consistent about using "python3" by default.

Thank you nkadel for your response but I am running the ansible on ubuntu mate not the CentOS. I tried removing ansible from the ubuntu host and re-installing it like you said but I got an error message. Please see below
!
user@ansible-controller:~$ sudo apt install ansible-core -y

You need install python in CenOS.

sorry I re read, you need define python interpreter
