Win10 TensorFlow CPU 导入问题

Question

尝试在 Windows 10 上安装 Tensorflow CPU，我下载了最新的 python 3.5.x 环境，这是我在导入 TF 时得到的。 我需要每个 microsoft dll（即 vc_redist.x64 ）......也许应该使用另一个 python 版本？请帮忙。

 >>> import tensorflow
Traceback (most recent call last):

在处理上述异常的过程中，又发生了一个异常：

Answer 1

Theano 有一个相关社区question。

当您选择pip install 时，总是有可能出现此类问题。我已经使用 anaconda 在我的 windows10 机器上设置了 tensorflow。它相当容易做到。这个社区question 还可以通过在答案之间滚动来指导您完成设置。

总结一下设置：

1)。从here 下载 anaconda 并安装安装程序（所有下一步点击和特定路径）

2)。打开 Anaconda Navigator 并在下面输入：

$ conda create --name mytensorflowenv (this will automatically take the python version of conda)
$ activate mytensorflowenv
$ conda install tensorflow (this will fetch latest tf available with conda)

3)。测试张量流导入

python
import tensorflow

它应该可以工作。

Answer 2

如果您不想安装 anaconda，请阅读以下内容：

如果你在win10（python3.5.x）中正确安装了tensoflow 1.8 for cpu，并且出现错误，请尝试将版本更改为1.5 pip3 安装张量流==1.5 我花了一天时间才知道它:)
