本文解析了在使用TensorFlow CPU版本时遇到的关于AVX2 FMA指令集支持的警告信息，详细解释了该警告的意义，并提供了解决方案，即通过设置环境变量TF_CPP_MIN_LOG_LEVEL为2来屏蔽此警告。

遇见这个提示是什么意思？

背景：今天安装的tensorflow是cpu版本的 在写了一个小小的demo后 出现了一个提示：

            2018-10-15 16:14:02.486398: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA

意思：

            这个警告是告诉使用者，你的cpu是支持AVX的

如何去掉这个无关痛痒的警告：

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

兴致勃勃的写了第一个TensorFlow程序，结果又给出了提示，以为是错误，大胆的去百度，结果发现不是。 感谢这位仁兄的指导https://blog.youkuaiyun.com/CliuGeek/article/details/78836598 这个提示不是错误，而是类似一个建议，TensorFlow觉得你的CPU还不错，可以支持更快更好的模式，但是你目前的模式还稍微差了些。 这个提示并不影响程序...

这是一个包含多个错误信息的日志，其中第一行提示...最后几行是TensorFlow的信息，提示该二进制文件没有使用CPU的某些指令，以及正在创建新的线程池。开发者需要对这些错误信息进行逐一排查，找出问题所在并进行修复。
