我构建了一个涉及机器学习的Python Flask Web API，我在Heroku上部署它时遇到了很多麻烦。
问题是，我的应用程序依赖于Dlib（一个库），我似乎找不到在Heroku服务器中安装的方法。我正在试图解决这个问题而失去理智，我可以想象那些可能会遇到这个问题的其他AI开发人员。请帮帮我
这是我到目前为止所做的工作。
我尝试过不使用Buildpack，方法是在我的requirements.txt中指定dlib == 19.4.0及其依赖项，但由于依赖Boost而失败。
我研究了Dlib（https://www.pyimagesearch.com/2017/03/27/how-to-install-dlib/）的依赖关系;
build-essential cmake # I already have this in my requirements.txt
libgtk-3-dev
libboost-all-dev
此外，
numpy # I already have this in my requirements.txt
scipy # I already have this in my requirements.txt
sciKit-Image # I already have this in my requirements.txt
所以我包括了boost == 0.1，cmake == 0.7.1＆amp;我的requirements.txt文件中的boost-py == 1.00。 安装失败，这是构建日志

我也尝试过使用Heroku Buildpack，https://github.com/J-A-M-E-5/heroku16-buildpack-python3-opencv-dlib.git和https://github.com/J-A-M-E-5/heroku114-buildpack-python3-opencv-dlib.git 这几乎就像Heroku跳过了我的requirements.txt，只尝试安装Buildpacks。

当我打开应用程序时，我收到应用程序错误和log;

我观察到，如果我部署应用程序而不包含这些Buildpacks我没有使用gunicorn的错误，但我的app需要dlib。

随着对Dlib的最新更新，将Dlib添加到您的buildpack不再是一个问题，因为Boost依赖项已被删除https://github.com/davisking/dlib/issues/293

您需要cmake来安装dlib。要在heroku中安装cmake，您需要buildpack cmake并设置该内部版本以安装dlib。
您可以使用此buildpack进行cmake heroku-buildpack-cmake
在您的CLI中执行此操作
heroku create --buildpack https://github.com/VovchikMonkey/heroku-buildpack-cmake.git heroku buildpacks:set https://github.com/Starkast/heroku-buildpack-cmake $ git add .
$ git commit -am "make it better"
$ git push heroku大师
