The TensorFlow library wasn't compiled to use SSE instructions, but these are available on your machine and could speed up CPU computations.
W c:\tf_jenkins\home\workspace\release-win\m\windows\py\35\tensorflow\core\platform\cpu_feature_guard.cc:45] The TensorFlow library wasn't compiled to use SSE instructions, but these are available on your machine and could speed up CPU computations.
大概意思是
警告:你的机器是支持使用SSE指令的,使用SSE可以加速你的CPU计算。但是,你的Tensorflow库没有编译,所以用不了
遇到这个警告的原因是,你是使用例如 "pip install tensorflow" 这种方法安装的Tensorflow,而不是从源码编译安装的。
这只是个警告,只是影响cpu计算速度而已。使用或者不使用SSE你的程序都是可以运行的。
此外,如果你是使用的gpu版本,在gpu上的运行是不受SSE影响的。
