谷歌應用程序引擎POST 500失蹤模塊sklearn.pipeline

在用戶界面上運行：它接受一個字符串，將它帶到後端（使用Flask，名爲main.py），執行一些ML魔術，並將JSON返回到前端。谷歌應用程序引擎POST 500失蹤模塊sklearn.pipeline

在本地運行UI可以正常工作，但是在將其部署到Google的App Engine時，我會得到狀態500.查看日誌，我看到我有一個moduleError: No module named sklearn.pipeline事情是，我不使用它，也不是在我的requirements.txt下面是從日誌查看器中的回溯對象：

困惑什麼就在這一點上做的事：我應該安裝的模塊，並在我的main.py使用它？

我會後我找到了解決辦法：

雖然我main.py不需要SciPy的或sklearn，我需要無論在requirements.txt這些模塊的泡菜文件之一。在部署到App Engine時，請確保您的requirements.txt是一致的。
