kolla-ansible prechecks error : checking docker sdk version failed

i deploy openstack multinode with kolla-ansible. But i have this error: checking docker sdk version failed.

fatal: [controller]: FAILED! => {"changed": false, "cmd": ["/usr/bin/python", "-c", "import docker; print(docker.version)"], "delta": "0:00:00.011586", "end": "2020-11-25 13:40:32.457131", "failed_when_result": true, "msg": "non-zero return code", "rc": 1, "start": "2020-11-25 13:40:32.445545", "stderr": "Traceback (most recent call last):n File "", line 1, in nImportError: No module named docker", "stderr_lines": ["Traceback (most recent call last):", " File "", line 1, in ", "ImportError: No module named docker"], "stdout": "", "stdout_lines": []}

This is my configuration of all nodes:

docker = 19.03.13
