The project model of AI and ml but at last step it’s showing name error, after resolving this, it’s again showing value error and attribute error can anyone tell correct code :

NameError



Cell In[22], line 3



1 import matplotlib.pyplot as plt



2 plt.scatter(x_test,y_test)



----> 3 plt.plot(x_test, y_pred_test, color="red")



4 plt.xlabel("Temperature")



5 plt.ylabel("Revenue")



NameError: name 'y_pred_test' is not defined

I expect that output should be successful. But it doesn’t
