Ansibleの私の在庫

独自のマニフェストを作成し、3つのIPアドレスのうち2つを追加しましたが、次のコマンドを実行するとエラーが発生します。アドバイスをお願いします。

ansible all -i myinventory -m command -a 'Free'

間違い：

[DEPRECATION WARNING]: Distribution Ubuntu 18.04 on host 172.31.35.222 should use /usr/bin/python3, but is using /usr/bin/python for
backward compatibility with prior Ansible releases. A future Ansible release will default to using the discovered platform python for this

removed in version 2.12. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.

ansile.cfgでdeprecation_warnings設定を変更しようとしましたが、まだこのエラーが発生します。
