DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

今回はpython2の警告があります
実は、python2でTensorFlowをインストールしたので、python3でもTensorFlowを使いたいと考えています。プロンプトにはたくさんのコメントがあります。

動作します(?)、なぜ警告がたくさんあるのですか?
答え1
まず、Python 3 で tensorflow を使用するには、 を使用してインストールする必要がありますpip3。インストールされていない場合はpip3、 を使用してインストールできます。sudo apt install python3-pip
その後、次のコマンドを実行するだけで tensorflow をインストールできますpip3 install tensorflow。sudo を使用する必要はありません。
次に、NumPy のバージョンが原因で警告が表示されています。おそらく、インストールした TensorFlow のバージョンではサポートされていない NumPy バージョン (1.17 または 1.15) を使用している可能性があります。
したがって、これらの警告を解決するには、次の操作を実行できます。
- 最新バージョンのnumpyで問題なく動作するtensorflow 2.0をインストールします。コマンドは
pip3 install --upgrade tensoflow
または
- numpyを1.13.3<=numpy<=1.14.5にダウングレードし、tensorflowの現在のバージョンを維持します。コマンドは
pip3 install nupmpy==1.14
注意:警告が表示されても、インストールが失敗したわけではありません。Tensorflow は正常に動作するため、警告を無視すればすべて正常に動作します。
