Describe the bug

Hey folks, I've been trying out Flower recently and come up with the error when importing ClientApp
Here is the code:
from flwr.client import ClientApp
Here is the error:
ImportError: cannot import name 'ClientApp' from 'flwr.client'

My environment:

  • Ubuntu 20.04.6 LTS
  • Python 3.10.10 (conda)
  • flwr 1.4.0

Steps/Code to Reproduce

  1. Open Python in the terminal
  2. Run from flwr.client import ClientApp

Expected Results

The ClientApp should've been imported because there is a lot of tutorial-like source code that uses it.

Actual Results

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'ClientApp' from 'flwr.client' (/home/ubuntu/miniconda3/envs/pytorch-gpu/lib/python3.10/site-packages/flwr/client/__init__.py)
