tf.stack When merging data, tf.stack creates a new dimension and utilizes the parameter axis to define where to place the new dimension. When an axis is a positive number, a new dimension is added in front of the axis. When the axis is negative, a new dimension is added in the next place.

You can subtract the first sums from the second and subsequent sums by taking a linear subset of the cumulative sum: import numpy as np A = np.array([1, 2, 3, 4, 2, 3, 0, 1, 5, 3, 1, 0]) R = A.cumsum()[2::3] R[1:] -= R[:-1] print(R) Output: [6 9 6 4]
