【问题讨论】：

错误信息显示您的计算机与 pypi.python.org 的连接错误。

标签： python tensorflow timeout

【解决方案1】：

我通过这样修改命令解决了这个问题：

pip --default-timeout=100 install THEPACKAGENAME

【解决方案2】：

您也可以尝试使用 Wheel 包进行安装。 Wheel 软件包取决于您拥有的操作系统类型、python 版本以及是否要安装 CPU/GPU 支持。还要在安装 Tensorflow 之前升级你的 protobuf。

请在此处找到软件包列表： https://www.tensorflow.org/install/install_linux#the_url_of_the_tensorflow_python_package

然后你可以发出这个命令：

$ sudo pip  install --upgrade <TF wheel package URL>   - For Python 2.7
$ sudo pip3 install --upgrade <TF wheel package URL>   - For Python 3.x

Tensorflow 网站有一些关于一些常见安装问题的详细信息。你也可以看看这些，以防万一。
