python - Ubuntu Python : unable to pip install dlib - Failed building wheel for dlib and machine is almost stuck

Question

我正在尝试为我的 django python 环境安装 dlib(机器学习库)。但是，我无法安装它。有错误并卡住。

根据这个指令，这就是我所做的 https://www.pyimagesearch.com/2017/03/27/how-to-install-dlib/

$ sudo apt-get install build-essential cmake
$ sudo apt-get install libgtk-3-dev
$ sudo apt-get install libboost-all-dev

$ source somedotcomenv/bin/activate <-- virtualenv

$ pip install numpy
$ pip install scipy
$ pip install scikit-image
$ pip install dlib

但是，它失败了，我认为卡住了，在最后阶段将近一个小时。我不确定它是否仍在编译。

这是最后一个顶级进程，它不确定它是否仍在编译，但它已经过了一个小时。有什么东西卡住了。即使尝试在另一个命令行上键入内容也非常慢。

尝试在此拉取请求中使用 dlib 的版本 https://github.com/davisking/dlib/pull/1040 .它消除了对 boost 的依赖，因此应该可以解决您的问题。
