Example Analysis of Operation on tf.reduce_sum tensorflow Dimension

This article will explain in detail the example analysis of the operation on the tf.reduce_sum tensorflow dimension. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

There are many dimensional operations in tensorflow, and this example is illustrated by the commonly used tf.reduce_sum. Official api

Reduce_sum (input_tensor, axis=None, keep_dims=False, name=None, reduction_indices=None)

Input_tensor: indicates input

Axis: indicates that the sum operation is performed in that dimension.

Keep_dims: indicates whether to retain the dimension of the original data. False means that the original data will be missing one dimension after execution.

Reduction_indices: for compatibility with older versions, it is no longer in use.

Official examples:

#'x'is [[1,1,1] # [1,1,1]] tf.reduce_sum (x) = > 6tf.reduce_sum (x, 0) = > [2,2,2] tf.reduce_sum (x, 1) = > [3,3] tf.reduce_sum (x, 1, keep_dims=True) = > [3], [3]] tf.reduce_sum (x, [0,1]) = > 6

Examples made by yourself:

.. Axis=1: [[5 7 9] [17 19 21]] 1 "4 2" 5 3 + 6 … . Axis=2: [[6 15] [24 33]] 1, 2, 3, 4, 5, 6... ..
