警告：

The TensorFlow library wasn't compiled to use SSE4.2 instructions, but these are available on your machine and could speed up CPU computations.

在项目前添加这样一段代码：

[python]  view plain  copy

1. import os  
2. os.environ['TF_CPP_MIN_LOG_LEVEL']='2'  
3. import tensorflow as tf  

这是一个警告，并不影响tensorflow运行，上面这段代码表示忽略这个警告，和tensorflow的硬件加速有关。
