NameError Traceback (most recent call last)

[Melobeid]

Hi, I am trying the first exercise on jupyter notebook via anaconda navigator. However, when i try assigning the identity matrix,A = np.eye(5), and running the code (In [2]) I get the following errors:

NameError Traceback (most recent call last)

&

NameError: name 'np' is not defined

Is this an issue with my set up or configuration?

Your support is really appreciated!
