我构建了一个涉及机器学习的 Python Flask Web API，在 Heroku 上部署它时我遇到了很多挫折。
问题是，我的应用程序依赖于 Dlib(一个库)，而且我似乎找不到在我的 Heroku 服务器中安装的方法。我正在努力解决这个问题，我可以想象其他 AI 开发人员可能会遇到这个问题。请帮助我
这是我到目前为止所做的。
我尝试通过在我的 requirements.txt 中指定 dlib==19.4.0 及其依赖项来不使用 Buildpack，但由于对 Boost 的依赖性，它失败了。
我研究了 Dlib 的依赖性 ( https://www.pyimagesearch.com/2017/03/27/how-to-install-dlib/ );
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
所以我在我的 requirements.txt 文件中包含了 boost==0.1, cmake==0.7.1 & boost-py==1.00。 安装失败，这是构建日志

! Push rejected, failed to compile Python app.

我还尝试使用 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 就好像 Heroku 跳过了我的 requirements.txt 并且只尝试安装 Buildpacks。
这是日志文件:

然后当我打开该应用程序时，我收到带有日志的应用程序错误；

我观察到，如果我在不包含这些 Buildpack 的情况下部署应用程序，我在使用 gunicorn 时不会出错，但我的应用程序需要 dlib。
我的requirements.txt 文件:
gunicorn
click==6.7
cmake==0.7.1
colorthief==0.2.1
cycler==0.10.0
Flask==0.12.2
Flask-Gunicorn==0.1.1
imutils==0.4.3
itsdangerous==0.24
Jinja2==2.9.6

matplotlib==2.0.2

最佳答案
随着 Dlib 的最新更新，将 Dlib 添加到您的构建包应该不再是问题，因为 Boost 依赖项已被删除 https://github.com/davisking/dlib/issues/293
关于python - 如何使用 requirements.txt 在 Heroku python 网络应用程序中安装 Dlib？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46622227/
