ak.size

Defined in awkward.operations.structure on line 4240.

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 by 1, 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.
