我在谷歌应用引擎上部署了一个django应用程序(灵活的环境)。该应用程序在本地运行良好，部署(使用gcloud app deploy)也很顺利。虽然主页加载良好，但当我使用pickle从同一应用程序目录中的目录(通过POST请求)加载一些二进制数据(约40Mo)时，我得到502坏网关nginx错误。我尝试了许多建议的解决方案(将PORT更改为8080，添加gunicorn超时或添加-preload，更改工作人员的n°…)，但仍然存在问题。我认为问题来自于我加载了一个沉重的文件，因为我可以访问部署版本上的django admin .
我对gunicorn/nginx并不了解(这是我第一次部署应用程序)。如果你花了这么多时间在这上面，我将非常感谢你有一些想法!
日志文件没有显示任何错误:

正如@gaefan建议的那样，我需要最大化内存!我在yaml文件中尝试了10个memory_gb，它工作了。
