it shows this error
j[i,j]=np.sum((y-y_)**2)
'int' object does not support item assignment
Hey @yashaswiupmon, you have two variables showing the same name, in line 4 you initialized j = np.zeros(t00.shape) and in line 6 you again used it “for j in ran…” So change the variable name and rerun the code.
Hope this resolved your doubt.
