C2_W3_Assignment grades Error - wrong version

[Prabhat_Jha]

Hi @lucas.coutinho ,

Thanks for the prompt reply.
Here is the step-by-step process I did.

1. Once I got an error that my version of Jupyter Notebook was older, I saved the notebook on my local drive, went into the Help section, and updated the Lab. All answers were saved so I submitted the assignment which gave me the same error.
2. Then, I clicked on the file and clicked on Open after which I selected the file as shown in the picture
3. Then, I renamed the file “C2_W3_Assignment_v2” and ran the code which gave me the error.
   PS: I did not copy-paste the answers before submitting them.

Doubt: If I rename the file, that doesn’t reset the codes to “None”. All the codes are the same as it was.
How do I solve this?
