I have passed C3W2_Assignment with 80%, because method create_model have 0/20 points, due to error which I cant understand: There was a problem grading your submission. Details:
local variable ‘history’ referenced before assignment
But in Jupyter Notebook everything working fine and all cell executing without any error. I have checked variable ‘history’ and did not find any reference before assignment
If grader metadata is missing in your notebook, please follow these steps to refresh your workspace.
If that’s not the case, click my name and message your notebook as an attachment.
Thank you for your reply. After refreshing workspace I completed assignment again and its works fine. Probably error raised because I added additional cell for testing and forgot to delete it.
