scipy - 安装 MXNet 框架。在 Raspberry Pi 上 - SciPy 挂

Question

我正在尝试使用 mxnet 设置 AWS Greengrass，以便在 Raspberry Pi 上进行机器学习。

当从 https://docs.aws.amazon.com/greengrass/latest/developerguide/ml-console.html#install-mxnet 运行 ./mxnet_installer.sh 时这需要很长时间，并且只会断开我与 PuTTY 的 session 。

它似乎卡在 Running setup.py bdist_wheel for scipy - 在 PuTTY session 丢失之前，它在那里停留了大约 2 小时。

我在一个干净的 PI 上执行命令，所有事先完成的都是来自 https://docs.aws.amazon.com/greengrass/latest/developerguide/gg-gs.html 的模块 1 到 6

有什么建议吗？

Answer 1

1. 增加交换空间。
2. 手动安装 SciPy。从源构建。看 this answer
3. 运行mxnet_installer
