Tensorflow federated installation

Hi… I am a beginner in Tensorflow federated (in Python too)… I am having this difficulty in installing Tensorflow federated… I am running the following commands as suggested by the official site:

pip install --upgrade tensorflow-federated

The CMD is installing sort of all the versions of tff and is taking forever to finish:

tf_nightly-2.9.0.dev20220202-cp39-cp39-win_amd64.whl (348.6 MB)

tf_nightly-2.8.0.dev20211209-cp39-cp39-win_amd64.whl (341.6 MB)

is this normal or am I missing something?
