安装Tensorflow的问题 - 不是CUDA/CuDNN问题

Question

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
Traceback (most recent call last):
  File "C:\Users\[user]\AppData\Local\Programs\Python\Python36\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 14, in swig_import_helper

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

Answer 1

@ user1735003想通了.我没有使用最新版本的tensorflow

pip uninstall tensorflow

然后安装tensorflow 1.5

pip install tensorflow==1.5

然后我验证了安装与脚本一起工作

import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))

我得到了正确的输出

Hello, TensorFlow!

Answer 2

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.实际上从1.6开始,tensorflow预建二进制文件使用AVX指令.

目前您的选择是:

1. 使用TF 1.5或更早版本的官方预建二进制文件.(你会想念一些事情,但我会说).
2. 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conda installWindows上的TF 1.10开始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将会持续多长时间.
   • 请注意,conda-forge另一方面,来自(在主通道上可用之前的主要conda tensorflow提供程序)的二进制文件是使用AVX支持构建的.
3. 更改硬件以支持AVX(显然).
4. 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.
