pip install tesorflow で、TensorFlow 2.0 rc をインストールして、import してみると、次のエラーが発生。原因は、CPUが AVX（Advanced Vector Extensions）をサポートしていないためのようだ。Core i7なので、割と新しいと思っていたけど。orz

Tensorflowインストール不具合解決方法 を参考に、sseをインストールしてみる。
PS > pip install .\tensorflow-1.14.0-cp37-cp37m-win_amd64.whl により、sse をインストールしてみる。
import numpy as np
import matplotlib.pyplot as pltprint(tf.version)
1.14.0
その結果、TensorFlow のバージョンが 2.0 RC から、1.14.0 にダウンしている。ローカルでTF 2.0を試したかったのだけど、Google Colab で試すしかなさそう。
