Webb18 apr. 2024 · 1. I am creating a prediction machine with four variables. When I add the variables it all messes up and gives me: ValueError: shapes (1,4) and (5,4) not aligned: 4 … ValueError: shapes (1,1) and (4,1) not aligned: 1 (dim 1) != 4 (dim 0) So I am trying to implement (a * b) * (M * a.T) but I keep getting ValueError. As I am new to python and numpy functions, help would be great. Thanks in advance.
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! Webb11 jan. 2024 · Jun 30, 2024 at 8:21. The only answer that solved the issue for me!
