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'] = ''

说明：

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