@Aayushkh_333
In my program the shape of X_test is ((400, 5) but for Y_test i am getting the shape of (1600,)) not ((400,)).
Can you please tell me where I am going wrong

#4

Hey @naazsayma123, can you tell me how have you created Y_test in your code ? I guess you should read the test file and assign it’s last column as Y_test.

Let me know if there is any issue you are facing again !

Happy Learning ! :slightly_smiling_face:

@Aayushkh_333
I am doing this- Y_test=hypothesis(X_test,theta)

#6

Can you print the shapes of X_test and theta in code and tell me what are they coming ?

#7

Shape of X_test is (400,5)
and shape of theta is (6,)

#8

Yeah so now you can realise your mistake there right ? When you call hypothesis(X_test,theta) in your code, the dot product is not correct as the shape of X_test should also be (400,6). Only then you can take it’s dot product with theta of shape (6,). So please add an additional column of ones in X_test like you have done for X to make it of shape (400,6).

I hope this clears your doubt ! :slightly_smiling_face:
Happy Coding ! :+1:
