Databricks 中的 SQL 会话设置出错

Setup of SQL Session in Databricks gives error

我正在尝试在 databricks 社区版上练习 spark=sql, 并使用工作簿

https://files.training.databricks.com/courses/spark-sql/latest/amazon/Lessons.dbc

在第三步中,我在 SQL 会话

的设置过程中遇到错误

这是 python 会话中的命令

%run "./Includes/Classroom-Setup"

这是日志

Notebook not found: 
Users/amohammed@xxx.com/Includes/Classroom-Setup. 
Notebooks can be specified via a relative path 
(./Notebook or ../folder/Notebook) or via an absolute 
path (/Abs/Path/to/Notebook). Make sure you are 
specifying the path correctly.

Stacktrace:
/Users/amohammed@shuaa.com/First_Notebook: python
Command took 0.01 seconds -- by amohammed@xxx.com at

我在设置上下文时犯了什么错误

感谢期待

阿卜杜勒, 仔细检查您的笔记本是否连接了活动集群。
