MBP 安装好 tensorflow 环境后，程序运行正常，但是出现以下 warnings
2017-05-04 23:21:11.521746: W tensorflow/core/platform/cpu_feature_guard.cc:45] The TensorFlow library wasn't compiled to use SSE4.1 instructions, but these are available on your machine and could speed up CPU computations.

关掉这些 warnings，需要添加
import os
os.environ['TF_CPP_MIN_LOG_LEVEL']='2'
TF_CPP_MIN_LOG_LEVEL is a TensorFlow environment variable responsible for the logs
- silence INFO logs set it to 1
- filter out WARNING set it to 2 （过滤掉程序中的警告）
- silence ERROR logs (not recommended) set it to 3
