解决tensorflow的"Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA Using TensorFlow backend."警告问题

问题描述

程序开始运行的时候报出警告：

I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA

解决方法

加入下面两行代码，忽略警告：

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

说明：

os.environ["TF_CPP_MIN_LOG_LEVEL"] = '1' # 这是默认的显示等级，显示所有信息 
os.environ["TF_CPP_MIN_LOG_LEVEL"] = '2' # 只显示 warning 和 Error 
os.environ["TF_CPP_MIN_LOG_LEVEL"] = '3' # 只显示 Error
