- ak.size(array, axis=None)¶
- Parameters
array – Rectilinear array whose
shape
needs to be known.axis (int) – The dimension at which this operation is applied. The outermost dimension is
0
, followed by1
, etc., and negative values count backward from the innermost:-1
is the innermost dimension,-2
is the next level up, etc.
Returns an int or a list of ints, one for each regular dimension.
Implements NumPy’s
size
function in a way that accepts ak.Array
as the array
.
If the array
is not rectilinear (i.e. if #np.to_numpy would raise an
error), then this function raise an error.
