Why my notebook I created in a Repo can be opened safe?

[dnchankov]

I've cloned a Repo during "Get Started with Data Engineering on Databricks".

Then I'm trying to run another notebook from a cell with a magic %run command.

But I get that the file can't be opened safe.

Here my code:

notebook_a

name = "John"
print(f"Hello {name}")
%run ./notebook_b3
print(f"Welcome back John {full_name2}")

notebook_b3:

full_name2 = "Todorov"

Error

/databricks/python/lib/python3.10/site-packages/IPython/core/interactiveshell.py:2807: UserWarning: Could not open file </Workspace/Repos/dnchankov@abv.bg/my_databricks_course/my_folder/notebook_b3> for safe execution.
  warn('Could not open file <%s> for safe execution.' % fname)
NameError: name 'full_name2' is not defined

Thanks in advance!

Opening in Confined Mode is the most secure choice and you can constantly resume the record in your unique Versus Code window once you decide the document is reliable.

It could be that you need to put the %run in a cell all by itself.

Hi,

 

Just sharing this here for future reference in case it helps other users. 

I ran into the same warning/error, and the solution is indeed what @petermeissner pointed out.

 

The %run command must be in a cell by itself.

In my case, having a comment in the `%run` cell was the reason the error occurred.

+1 to all the above comments. Having the %run command along with other commands will confuse the REPL execution. So, have the %run notebook_b3 command alone in a new cell, maybe as the first cell, is notebook_a, which will resolve the issue, and your variables can also be accessed anywhere in notebook_a.
