I deleted some rows and rewrite them and solve them all. But, when submitted for grading, it could not grade me.
This shows error, even if I have defined ‘MultiplyRow’ function.

There was a problem compiling the code from your notebook. Details:
name ‘MultiplyRow’ is not defined

At this point its better to perform of reset of the notebook. Just search jupyter notenook force refresh in google and a link will guide you.

Hi @Prajwal_Khanal ,

Try these steps:
Kernel → restart and clear all output
Cell → run all

After checking all the outputs are as expected, then, submit your assignment.

@Kic ,
Even after restarting kernel and clearing output the grading was not performed.

Open your notebook
Rename it some different name
After renaming just add ?forceRefresh=true to the end of your notebook URL
and then press enter key

Now You have
old renamed version and
new refreshed to default one

This works. Thanks a lot.

But it doesn’t works to me
