Tensorflowを使ってFedarated Learningを試す

インストール方法

公式を見よう。

https://www.tensorflow.org/federated/install

Linuxの場合

環境:
OS Ubuntu 18.04.5 LTS(Bionic Beaver)
Python  2.7.17
Python3 3.6.9
virtualenv 15.1.0 (環境破壊する可能性あるので~)

モジュール設定:
<OS>
sudo apt update
sudo apt install python3-dev python3-pip # Python 3
<virtualenv>
sudo pip3 install --user --upgrade virtualenv
virtualenv --python python3 "venv"
source "venv/bin/activate"
<TensorFlow Federated>
pip install --upgrade pip
pip install --upgrade tensorflow_federated
python -c "import tensorflow_federated as tff; print(tff.federated_computation(lambda: 'Hello World')())"

macの場合

OS: 10.15.7 Catalina
Python 2.7.16
Python3 3.8.2

設定

% brew update
% brew install python  # Python 3 に関して、Python3以外の周辺系がインストールされる
% pip3 install --user --upgrade virtualenv  

公式ではsudoを指定しているが、不要か。sudoすると、virtualenvの入っているディレクトリにパスを通す(または権限の変更)を必要が出てくる。あんまりroot権限を使いたくないので、これで十分。

% virtualenv --python python3 "venv" # Python3をベースにしたvenvという名前の作業ディレクトリを作成
% source "venv/bin/activate" # venvディレクトリ内の設定をロードし、virtualenvモードに移行 
  # プロンプトの前に(venv) が出る。
(venv) % pip install --upgrade pip
(venv) % pip install --upgrade tensorflow_federated

ここでエラーがでる。

ERROR: Cannot install tensorflow-federated==0.1.0, tensorflow-federated==0.10.0, tensorflow-federated==0.10.1, tensorflow-federated==0.11.0, tensorflow-federated==0.12.0, tensorflow-federated==0.13.0, tensorflow-federated==0.13.1, tensorflow-federated==0.14.0, tensorflow-federated==0.15.0, tensorflow-federated==0.16.0, tensorflow-federated==0.16.1, tensorflow-federated==0.17.0, tensorflow-federated==0.2.0, tensorflow-federated==0.3.0, tensorflow-federated==0.4.0, tensorflow-federated==0.5.0, tensorflow-federated==0.6.0, tensorflow-federated==0.7.0 and tensorflow-federated==0.9.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    tensorflow-federated 0.17.0 depends on tensorflow-addons~=0.11.1
    tensorflow-federated 0.16.1 depends on tensorflow~=2.2.0
    tensorflow-federated 0.16.0 depends on tensorflow~=2.2.0
    tensorflow-federated 0.15.0 depends on tensorflow~=2.2.0
    tensorflow-federated 0.14.0 depends on tensorflow-addons~=0.9.1
    tensorflow-federated 0.13.1 depends on tensorflow-addons~=0.8.3
    tensorflow-federated 0.13.0 depends on tensorflow-addons~=0.8.3
    tensorflow-federated 0.12.0 depends on tensorflow-addons~=0.7.0
    tensorflow-federated 0.11.0 depends on tensorflow-addons~=0.6.0
    tensorflow-federated 0.10.1 depends on tensorflow-addons~=0.6.0
    tensorflow-federated 0.10.0 depends on tensorflow~=2.0.0
    tensorflow-federated 0.9.0 depends on tf-nightly
    tensorflow-federated 0.7.0 depends on tf-nightly
    tensorflow-federated 0.6.0 depends on tf-nightly
    tensorflow-federated 0.5.0 depends on tf-nightly
    tensorflow-federated 0.4.0 depends on tensorflow~=1.13
    tensorflow-federated 0.3.0 depends on tensorflow~=1.13
    tensorflow-federated 0.2.0 depends on tensorflow~=1.13
    tensorflow-federated 0.1.0 depends on tensorflow>=1.13.0rc2

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
