安装 MXNet 框架。在 Raspberry Pi - SciPy 挂起

Question

我正在尝试在 Raspberry Pi.

上使用 mxnet 设置 AWS Greengrass 以进行机器学习

当运行 ./mxnet_installer.sh 从 https://docs.aws.amazon.com/greengrass/latest/developerguide/ml-console.html#install-mxnet 开始时，它需要很长时间，并且只是断开我与 PuTTY 的会话。

它似乎挂在 Running setup.py bdist_wheel for scipy - 在 PuTTY 会话丢失之前，它在那里停留了大约 2 小时。

我正在一个干净的 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
