hey @gauthampkrishnan ,
it seems to be a error in your target y and predicted y shapes. Kindly have a look at them and if still you can’t get it , then kindly provide me with a link to your code file , so that i can have a look and understand what is the problem.

Thank You.

I was unable to solve that error please help here is the link to the code and test and trainining files https://github.com/gauthampkrishnan/Air_Pollution_Prediction_Multilabel_Regression/blob/master/Air_Pollution.ipynb

hey @gauthampkrishnan ,
Gradient Descent to train our model to find patterns while training on a dataset , not on testing.
Gradient Descent requires two parameters features( X ) and target ( Y ) which is only available in training data , to get predictions you just need to use ,

hypothesis(df2,theta)

as it returns y_ which you requires.

y_test = gradient_descent(df2,theta)

in this above code of line you are providing your theta values as to be the y ( target variable ) and hence you receive different shapes error as X is of 400 in length and theta is only 6.

I hope this would have resolved your doubt.
Thank You and Happy Learning :slightly_smiling_face:.
