报错:Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2
1.问题
写了一个简单的单层神经网络跑mnist手写数字集,结果每次fit都会出现dead kernel

很多dead kernel首先不要急着去网上搜dead kernel怎么解决,因为大家出现的原因并不相同,应该去notebook的bash终端查看报错信息,大概如下:

看到一篇博客解释这个问题解释的比较好:

根据报错,首先了解一下什么是AVX:

大概意思是说AVX是一种扩展指令之类的,需要CPU和协议的配合,而我的Tensorflow不支持它。

2.解决方法
可能是由于mac版的tensorflow版本较低(相较于windows,还不能乱升级),那么怎么解决?


就可以了,我也想搞清楚这背后到底是什么问题,但是好像越看越复杂-。-,还是乖乖忽略警告跑代码吧
