Hello SKBansal,

Welcome to the community!

When you get a name error that means you have missed running the previous cell somehow, which is why, you are getting this error:

NameError: name ‘sigmoid_test’ is not defined

Check it once and re-run it.

Hi @skbansal97 ,

The execution environment is out of sync. To reset it, at the top of the menu bar of your notebook:

click Kernel ->restart & clear all output
click Cell → run all above (from your current cell)

This will reset the execution environment and bring in all the libraries and files to run your code.
