无法与“ Python”脚本的运行时通信。请检查“ Python”运行时的要求

Question

有人知道如何在下面解决此错误吗？我正在使用SQL Server 2017在数据库中运行Python。应该已经正确设置了编码环境，并且直到上周为止都没有任何问题地运行代码，并且我没有对SQL Server进行任何更改。

---

示例代码：

exec sp_execute_external_script 
@language =N'Python',
@script=N'OutputDataSet = InputDataSet
print("Input data is {0}".format(InputDataSet))
', 
@input_data_1 = N'SELECT 1 as col'

错误消息：

Msg 39012, Level 16, State 1, Line 25
