使用anaconda3 python 3.5进行Tensorflow安装时出现“读取超时错误”

我正在尝试使用python3.6和anaconda 3安装tensorflow-gpu，我正在遵循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创建-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（tensorflow）C：>

但是这是在我的conda环境中安装TensorFlow的最后一步。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

好吧，那之后我尝试安装cpu版本，我遇到了同样的错误。如果有人能帮助我，我将很感激，我真的很想开始学习tensorflow。
