hey @Shubhankit-Tiwari-1738649599558824,
Please save your code at IDE and share the link here.

#4

There’s just only one single mistake with the code, In line number 17, it should be
grad=np.dot(X.T,(y_-y))

I hope you know that the formula is
theta_j’ = theta_j - lr * sigma((hypothesis(Xi) - yi)*X_i_j)/m

So it should be y_-y and not y-y_

Hope this cleared your doubt.
:blush:

https://ide.codingblocks.com/s/177841 actually the problem still persist , I was able to work with it and even submmited the solution to air quality prediction with 96% accuracy but after a while the code stared working like it use to work before and started giving runtime error,plotting wrong graph

I ran your code it ran completely fine, the code would give runtime error if you are working with wrong matrices having wrong shapes, graph may be wrong because of high learning rate.

If still error persists, you are requested to share link of your ipynb file, after saving it on google drive.
Also it seems quite illogical that code running fine, starts misbehaving without any change, This doesn’t seem feasible. But anyways lets have a look on it.

You didn’t removed the target column from the X numpy array.
Here is the code
