Error docker on import

Hello, I use docker api within a docker. When I try to import docker api within a docker, I have this import error, would you have an idea about how to solve it ?

docker version 4.2.2

    import docker
  File "/usr/local/lib/python3.6/site-packages/docker/__init__.py", line 2, in <module>
    from .api import APIClient
  File "/usr/local/lib/python3.6/site-packages/docker/api/__init__.py", line 2, in <module>
    from .client import APIClient
  File "/usr/local/lib/python3.6/site-packages/docker/api/client.py", line 6, in <module>
    import requests.exceptions
ModuleNotFoundError: No module named 'requests.exceptions'; 'requests' is not a package

docker_compose.yml
server:
image: python3.6
....
volumes:
- /var/run/docker.sock:/var/run/docker.sock

Any suggestion is helpful.
Thanks

Start with the provided import traceback and the docker_compose.yml service configuration, including the mounted Docker socket. Reproduce the import in the stated Python 3.6 container with Docker version 4.2.2; done when the Docker API module imports without the reported requests.exceptions error.
