使用 anaconda3 python 3.5 安装 TensorFlow 时出现“读取超时错误”答案

【问题标题】：Tensorflow instalation with anaconda3 python 3.5 got 'Read timed out error"使用 anaconda3 python 3.5 安装 TensorFlow 时出现“读取超时错误”

【问题描述】：

我正在尝试安装 tensorflow-gpu 使用 python3.6 和 anaconda 3 我正在按照以下链接中的安装步骤https://www.tensorflow.org/install/install_windows

1- 我通过调用以下命令创建了一个名为 tensorflow 的 conda 环境：

C:> conda create -n tensorflow python=3.6

2- 然后通过发出以下命令激活 conda 环境：

C:> 激活张量流 (张量流)C:>

但即将完成最后一步，在我的 conda 环境中安装 TensorFlow。使用该命令 pip install --ignore-installed --upgrade tensorflow-gpu 我得到了那个错误

(C:\Users\Chaymae\Anaconda3) C:\WINDOWS\system32>activate tensorflow

(tensorflow) C:\WINDOWS\system32>pip install --ignore-installed --upgrade tensorflow-gpu

然后我尝试安装 cpu 版本，我得到了同样的错误。如果有人可以帮助我，我将不胜感激，我真的很想开始学习 tensorflow。

【问题讨论】：

好像是网络连接错误。再次尝试时，错误是否出现在完全相同的位置（5%）？
没有不一样的地方
然后你可以尝试再次下载，希望连接不会中止。如果每次都失败，您可以手动下载。但为此，您必须知道 URL。您可能还需要一个可以处理不稳定的 Internet 连接并自动恢复下载的工具。
"SSLError: The read operation timed out" when using pip的可能重复
@user502144 工具，可以从命令提示符处理不稳定的 Internet 连接？

【解决方案1】：

超时也有同样的问题。

做了pip --default-timeout=300 install tensorflow，但仍然遇到同样的问题。

在网上搜索更多信息，我设法使用pip 安装 TF。

这是我为解决这个问题所做的：

先运行这一行

conda config --set ssl_verify no

按照这个（你可以更改超时或不超时就尝试）

pip --default-timeout=300 install tensorflow

【解决方案2】：

只是网络不稳定的问题，现在已经安装好了，运行良好

【讨论】：

【解决方案3】：

确实是网络不稳定的问题。您可以将默认超时设置为 60（秒）。例如pip --default-timeout=60 安装张量流
