WebAug 25, 2024 · It starts with the trailing (i.e. rightmost) dimensions and works its way left. Two dimensions are compatible when . they are equal, or; one of them is 1; If these conditions are not met, a ValueError: operands could not be broadcast together exception is thrown, indicating that the arrays have incompatible shapes. WebSep 12, 2024 · The `ValueError: Cannot broadcast dimensions (562, 5) (5,)` is caused by the change of utility function values_in_time, it will always treat multi-index dataframe as multi-period prediction, neglecting the case of multi-index [t, symbol]. Therefore we will have to drop symbol index level to make it work.

The arrays can be broadcast together if they are compatible … WebAug 9, 2024 · Strictly, arithmetic may only be performed on arrays that have the same dimensions and dimensions with the same size. This means that a one-dimensional array with the length of 10 can only perform arithmetic with another one-dimensional array with the length 10. This limitation on array arithmetic is quite limiting indeed. WebJun 6, 2015 · NumPy isn't able to broadcast arrays with these shapes together because the lengths of the first axes are not compatible (they need to be the same length, or one of them needs to be 1 ). Inserting the extra dimension, data [:, None] has shape (3, 1, 2) and then the lengths of the axes align correctly: cyprus nearest sea port
