Thanks for your report.
Restarting the kernel is a good idea, because it forces the notebook to be re-complied.
Hello, Iāve run into the problem as well. The exercises return the expected result, but my submission gets a 0%. I have added and removed cells, restarted and cleared the kernel, and probably just messed the environment up. If you could wipe this lab, or tell me how to clear this I would appreciate it.
Lab ID: lapdrxnd
C1_W2_Linear_Regression
Thanks in advance for your help.
Note that only the course staff (e.g. Mubsi) have the superpower to examine or reset anyone elseās notebooks. The mentors are just fellow students and we canāt do anything with other peoplesā notebooks.
But the good news is that you can reset it yourself. There are instructions in the very first topic on the DLS FAQ Thread. If this is your first time visiting that thread, itās worth making a quick scan to see what all is covered there in addition to this pont.
One other caveat: the notebook name you quote is from MLS, not from DLS. This thread is in the DLS Course 4 subcategory. I have no experience with MLS, so I donāt know if the same properties of the grader being sensitive to added cells applies there as well. But note that a lot of the topics on the DLS FAQ Thread are generic and apply to MLS as well. In particular the āget a clean copyā procedure applies to any of the courses that use the Jupyter Notebooks.
Thank you paulinpaloalto, that worked. You are indeed a Super Mentor!
Itās great to hear that the solution worked. Thanks for confirming!
