我正在尝试在使用pytorch的gcloud上部署一个烧瓶应用程序。当我在本地运行服务器它工作正常。但是当我使用gcloud app deploy部署相同的代码时，会出现以下错误。

通过使用您提供的相同app.yaml和requirements.txt片段，我能够重现您获得的错误。
我尝试将app.yaml文件中的python_version值更改为3而不是2，并且部署工作正常。
因此，如果Python 3适合您而不影响项目中的其他库，那么这可能是一个解决方案。
我还尝试删除requirements.txt文件中的torch和torchvision行，并将Python版本保持为2.该配置已成功部署。
问题似乎是Pytorch和App Engine上的Python 2之间的兼容性问题。我建议检查Pytorch forums，看看是否有其他人有类似的问题。
