Question

在UI上运行：它接受一个字符串，将其带到后端（使用Flask，名为main.py），执行一些ML魔法，并将JSON返回到前端。

在本地运行用户界面工作正常，但是当将其部署到Google的App Engine时，我获得状态500.查看日志，我看到我有moduleError: No module named sklearn.pipeline事情是，我不是＆＃ 39; t使用它，这也不是我的requirements.txt这里的日志查看器中的追溯对象：

对于此时该做什么感到困惑：我应该安装模块并在main.py中使用它吗？

Answer 1

我会发布我发现的解决方案：

虽然我的main.py不需要scipy或sklearn，但我需要在requirements.txt中为其中一个pickle文件提供这些模块。在部署到App Engine时，必须确保您的requirements.txt是一致的。
