C2 W1: There was a problem compiling the code from your notebook. Details: name 'schema' is not defined

Course Q&A Machine Learning Engineering for Production(MLOps) Machine Learning Data Lifecycle in Production

Whenever I submit an assignment in C2: W1, it is not giving any points but shows the same errors for all 9 exercises. The error: There was a problem compiling the code from your notebook. Details:
name ‘schema’ is not defined
But I have defined the schema. Also using schema is only required in Exercise 3: Infer the training set schema (which I have defined as well). But here I am not able to understand why I am getting the error of schema even before that.
Any suggestions/ideas will be welcomed. (I have updated my chrome and cleared the cookies)

Hello Balaji,

Thanks for the suggestion. In the link given, it was asked to check if the meta data has got the tag graded or not. But in my case, the ipynb has already got the tag. PFBS for sample:

I have sent you the notebook. Please let me know if I missed any.

Exercise 3 cell containing code schema=... doesn’t have grader metadata. This is the metadata for the cell:

{
  "trusted": false
}

Please refresh your workspace.

Hello Balaji,

Thanks for your help. I have reloaded the notebook and it got executed after reloading it multiple times.
