"msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this. ?Please add this host's fingerprint to your known_hosts file to manage this host."
解决：
打开ansible.cfg文件位置，/etc/ansible/ansible.cfg
去掉注释即可
# uncomment this to disable SSH key host checking
host_key_checking = False

[WARNING]: Platform linux on host ai_host_1 is using the discovered Python interpreter at /usr/bin/python, but future
installation of another Python interpreter could change this. See
https://docs.ansible.com/ansible/2.9/reference_appendices/interpreter_discovery.html for more information.?
解决：
在ansible.cfg的[defaults]部分添加
interpreter_python = auto_legacy_silent
