fig = plt.figure() and ax = fig.gca(projection='3d') needs to be ax = plt.figure().add_subplot(projection='3d') part7 and also the other 3d models
#3D plot:
#Uncomment to plot out-of-notebook (you'll be able to rotate)
#%matplotlib qt

#Scatter training examples:
ax.scatter(10X[:,0], 5X[:,1], 100*y, c='k', alpha = 1, s=30)

surf = ax.plot_surface(xx, yy, 100*allOutputs.reshape(100, 100),

ax.set_xlabel('Hours Sleep')
ax.set_ylabel('Hours Study')
