我在我的Ubuntu 17.04 32bit上使用bazel编译了Tensorflow，我用pip安装了结果.whl。但是当我尝试导入tensorflow时，我收到了这个错误

编辑： 如果我在使用'./configure'时添加'O2'，我得到了这个：

答案 0 :(得分：1)
似乎-march = native指令在32位盒子上无法正常工作。使用O2代替我解决了这个问题。
您可以在配置期间选择-O2
$ ./configure
Please specify the location of python. [Default is /usr/bin/python]:
Please specify optimization flags to use during compilation [Default is -march=native]: O2
