Description

Dear Support Team,

I am having difficulties completing the “Assess Task” for exercises 0, 1, and 2.

I have tried to redo the exercises several times, but the “Assess Task“ keeps failing. I am concerned as I am close to running out of available time in the environment.

For your analysis, I am attaching screenshots and the three notebooks (exercises 0, 1, and 2). I was able to run all cells sequentially and successfully in all of them.

I would like to clarify a few points to try and diagnose the problem:

  • Is the only requirement for conclude “Assess Task” to ensure that all cells are executed successfully?

  • In exercise 2, the last cell executed successfully but generated a “warning”. I have attached a screenshot of this. Does this combination (Success + Warning) prevent the task from being approved?

I am also attaching the exact error message I receive when I try to submit the assessment.

Note: For security reasons, I have hidden my NVIDIA api key in one of the cells in exercise 1.

I appreciate any guidance you can provide to help me resolve this issue.

Sincerely, Alberto Granja.

Environment

Warning that I receive, however, does not seem to be an impediment as it is not an error.
