So if you have a 2-dimensional array where 1 of the dimensions only has length 1, see if you can reduce the dimension. (see below) The problem in (2) is solved when …
WebArray broadcasting cannot accommodate arbitrary combinations of array shapes. For example, a (7,5)-shape array is incompatible with a shape-(11,3) array. ... one of the dimensions has a size of 1. The two arrays are broadcast-compatible if either of these conditions are satisfied for each pair of aligned dimensions. Web1 Answer Sorted by: 23 If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample ), then you will get this type of error.
