python – 运行导入tensorflow后的非法指令(核心转储)

2019-09-27 05:54:54 阅读：503 来源： 互联网

我创建了一个全新的虚拟环境：virtualenv -p python2 test_venv /
并安装了tensorflow：pip install –upgrade –no-cache-dir tensorflow

import tensorflow给了我非法指令(核心转储)

请帮助我了解发生了什么以及如何解决它.谢谢.

解决方法:

我会使用旧版本.看起来你的CPU不支持AVX指令.

引自他们的Release Page

Breaking Changes
Prebuilt binaries are now built against CUDA 9.0 and cuDNN 7.
Prebuilt binaries will use AVX instructions. This may break TF on older CPUs.

你有至少两个选择：

>使用tensorflow 1.5或更早版本
>从源代码构建

关于您对差异的关注,您将错过新功能,但大多数基本功能和文档都没有那么不同.
