Question

当我跑

时

sudo pip install -U scipy

首先下载，然后继续显示

Running setup.py install for scipy

但它冻结了。我尝试升级pip本身。工作得很好。我的点子版本是1.5.4

我得到的唯一错误是InsecurePlatforWarning。完整输出如下所示：

tom@tom-ThinkPad-Edge-E430:~$ sudo pip install -U scipy

Answer 1

花了很长时间，但几分钟后就结束了。所以问题就解决了。

Answer 2

做

sudo apt-get install python-scipy

对于python2

或

sudo apt-get install python3-scipy

如果您不关心版本。在几秒钟内在RPI3上安装

Answer 3

将交换大小从 100M 增加到 1024M 解决了具有 1G RAM 的 Raspberry Pi 3 上的问题。仍然花了很长时间（约 1 小时）但不再冻结。
