Problem in Surface Plots and Contours

The link to code is

I am getting error in line no 9 . Please tell what is the error as this is the exact code which sir wrote in video.

Hey @abhaygarg2001 , matplotlib’s current version requires us to import another library for 3D-plots which is :

from mpl_toolkits.mplot3d import Axes3D 

Try adding this to your code. Hope this helps.
Happy Learning :slight_smile:

Also dont call the function
axes = fig.gca(projection = ‘3d’)

Call this instead
axes = Axes3D(fig)
