Webb28 sep. 2024 · 1 taneemishere commented on Nov 5, 2024 In the part where it says initialize the parameters, there you should write it as: w, b = initialize_with_zeros (X_train.shape [0]) The error occurs because we write X.shape [0] and there in the model () we don't have X we have X_train. I hope this will solve the issue!
