我試圖運行與Python擴展本地使用VS 2017U型SQL，Python和本地執行， 「設備未找到」 錯誤
我按照這些步驟爲U-SQL作業：
然後我試圖るn這個：
，如果我在Azure上運行它，它工作正常，但如果我嘗試在本地運行它，我得到的錯誤是：「設備不被讀取「。

我知道，博客文章中提到，在本地運行Python擴展不正式支持，但他們並使其聽起來像它應該至少有可能以某種方式？
如果我不在本地使用Python擴展而運行U-SQL腳本，則不會收到任何錯誤。
有什麼我失蹤？有沒有我可以打開的日誌來了解更多信息？有沒有人成功地在本地使用U-SQL運行Python？
我聯繫了當地隊伍，看他們是否可以提供幫助。 –
