The cost after training is 6.78395445.
The resulting vector of weights is [4.1e-07, 0.00035658, 7.309e-05]

Expected output

The cost after training is 0.67094970.
The resulting vector of weights is [4.1e-07, 0.00035658, 7.309e-05]

I edited your post to delete your code, you edited your post to add code again. Please note that sharing your code in a public thread is strictly prohibited by the community code of conduct and if you keep sharing your code, this will lead to suspend your account.

Regarding your query, use dot product and don’t need to use sum function.
