pycharm运行TensorFlow警告：Your CPU supports instructions that this TensorFlow binary was not compiled to

还有警告如下：The TensorFlow library wasn't compiled to use SSE instructions, but these are available on your machine and could speed up CPU computations.

原始代码如下：

import tensorflow as tf
hello=tf.constant("Hello!")
sess=tf.Session()
print(sess.run(hello))

加入如下两行代码，问题解决，警告消失

import os
os.environ['TF_CPP_MIN_LOG_LEVEL']='2'
