在pycharm中安装tensorflow后
在这里插入图片描述
运行如下测试代码：

import tensorflow as tf
x = tf.Variable(3, name="x")
y = tf.Variable(4, name="y")
f = x*x*y + y + 2
print(f)

发现会报一行错误在这里插入图片描述
Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2大概意思是安装的tensorflow版本不支持cpu的AVX2编译
可能是因为安装时使用的pip install tensorflow ，这样默认会下载X86_64的SIMD版本。
查找解决办法后，有以下两种办法：

1.忽略屏蔽这个警告

在代码最前面添加如下两行代码

import os
os.environ["TF_CPP_MIN_LOG_LEVEL"]='2' # 只显示 warning 和 Error
2.彻底解决，换成支持cpu用AVX2编译的TensorFlow版本。

首先卸载原来安装的tensorflow版本
pip uninstall tensorflow
在这里下载对应版本的tensorflow：https://github.com/fo40225/tensorflow-windows-wheel，比如我需要的是CPU+AVX2+Python3.6，那么我就在下面的列表中选择这个：
