windows – 安装Tensorflow的问题 – 不是CUDA / CuDNN问题

我最近开始进入Tensorflow,但我遇到了安装问题.每次我尝试导入它时,我都会收到以下错误

>>> import tensorflow as tf

Failed to load the native TensorFlow runtime.

我查看了与我有同样问题的其他堆栈溢出帖子,他们建议从NVIDIA获取CUDA库.问题是,我既没有NVIDIA显卡也没有GPU版本的张量流,所以我不认为这是问题所在.还有一些建议可以确保安装Visual Studio的Microsoft可再发行组件.

如果这是一个基于系统变量的问题,我很感激帮助改变系统变量,因为我是新手.谢谢！

一些系统信息：

>操作系统：Microsoft Windows 10 Pro版本10.0.17134
> CPU：Intel Xeon E5620
>显卡：Radeon RX 480
> Python版本：3.6.5 amd64 Tensorflow
>安装方法：pip install tensorflow

我的猜测是你试图使用TF> = 1.6,因为你的CPU相当老,不支持AVX指令.确实从1.6上,tensorflow pre-built binaries use AVX instructions.

目前您的选择是：

>使用TF 1.5或更早版本的官方预构建二进制文件. (你会错过一些事情,但我会说).
>搜索不支持AVX的TF> = 1.6的非官方预构建二进制文件.

>目前,从Windows上的conda安装到TF 1.10之前预先构建的二进制文件似乎不是用AVX支持构建的,虽然我无法在任何地方找到这些信息,因此无法判断这是否是故意的以及情况会持续多长时间.
>请注意,另一方面来自conda-forge的二进制文件(在主要通道上可用之前曾是主要的conda tensorflow提供程序)是使用AVX支持构建的.

>更改硬件以支持AVX(显然).>在没有AVX指令的情况下编译自己的tensorflow二进制文件.如果没有其他可能的话,这是一个合理的选择.
