安装 SciPy 时出现问题

我正在尝试安装 Scipy 以在 Jupyter 上运行（在 VirtualBox Ubuntu OS、Windows 主机中）。我输入以下命令并出现错误。我该如何修复它？

python -m pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose

答案1

错误出现在您提供的跟踪中：socket.timeout: The read operation timed out 看起来您的互联网连接断断续续或断开。

您使用pip而不是有什么理由吗conda？

您可以使用以下方式安装 scipyconda install -c anaconda scipy
