Ansible: Shared connection to xxx closed - amazon-ec2

Question

Hello guys I make a simple playbook to practice with Ansible but I have a problem when I try to run the playbook (ansible-playbook -i hosts.ini playbook.yml) to configure an instance ec2 the output returns:
> fatal: [XX.XXX.XXX.XXX]: FAILED! => {
> "changed": false,
> "failed": true,
> "invocation": {
> "module_name": "setup"
> },
> "module_stderr": "Shared connection to XXX.XXX.XXX.XXX closed.\r\n",
> "module_stdout": "/bin/sh: 1: /usr/bin/python: not found\r\n",
> "msg": "MODULE FAILURE" } to retry, use: --limit #/home/douglas/Ansible/ansible_praticing/projeto2.retry
>
> PLAY RECAP
> *********************************************************************
> XX.XXX.XXX.XXX : ok=0 changed=0 unreachable=0 failed=1
When I try to connect with the instance via ssh -i ~/.ssh/key.pem ubuntu#public.ip it works well but the provisioning not.
My playbook:
- hosts: projeto
sudo: True
remote_user: ubuntu
vars_files:
- vars.yml
tasks:
- name: "Update"
apt: update_cache=yes
- name: "Install the Ansible"
apt: name=ansible state=latest
- name: "Installt the mysql"
apt:
args:
name: mysql-server
state: latest
- name: "Install the Nginx"
apt:
args:
name: nginx
state: latest
My hosts.ini is also ok (with public ip of aws ec2 instance) and I put the public key (~/.ssh/id_rsa.pem of local machine) in the ~/.ssh/authorized_keys file, inside of the instance.
In the last week (Friday) this playbook was working well.
What am I doing wrong?

Maybe my answer is too late but I faced the same problem today. I have an Ubuntu 16.04 instance running on my EC2. I think, since it has Python 3 (Python 3.5) as its default Python installation. Hence, ansible is not able to find the required Python directory (/usr/bin/python). I got around this issue by changing the ansible Python interpreter to Python 3.
I added ansible_python_interpreter=/usr/bin/python3 to my inventory file and did not have to change the playbook.
