TensorFlow : インストール2022/09/08

	機械学習ライブラリー, TensorFlow をインストールします。
[1]	こちらを参考に CUDA 11.5 をインストールしておきます。
[2]	こちらの [1] を参考に Python 3 をインストールしておきます。
[3]	cuDNN (CUDA Deep Neural Network library)、および、その他必要なパッケージをインストールしておきます。

root@dlp:~#

apt -y install nvidia-cudnn python3-pip python3-dev python3-venv gcc g++ make

[4]	任意の一般ユーザーでログインして、TensorFlow インストール用の Python 仮想環境を準備します。

ubuntu@dlp:~$

python3 -m venv --system-site-packages ~/tensorflow

ubuntu@dlp:~$

source ~/tensorflow/bin/activate

(tensorflow) ubuntu@dlp:~$

[5]	TensorFlow 2.9 をインストールします。

(tensorflow) ubuntu@dlp:~$

pip3 install --upgrade tensorflow==2.9.0

# TensorFlow 動作確認

(tensorflow) ubuntu@dlp:~$

python3 -c "import tensorflow as tf;print(tf.reduce_sum(tf.random.normal([1000, 1000])))"
