import flwr as fl ModuleNotFoundError: No module named 'flwr'

pip install flwr

If you are using Jupyter Notebook or Google Colab, you can also prepend the ! character to run the command as a shell command within the notebook:

!pip install flwr

Airflow 2.1.2 doesn't support Celery 5 yet.

Long story short: just downgrade Celery provider:

$ pip install --upgrade apache-airflow-providers-celery==2.0.0

More details are within issue:
