tensorflow reshape,range用法

import tensorflow as tf

                 [[2,3],[4,5]],
                 [[6,7],[8,9]]
                 
               ],
                 tf.int32)

d1=tf.range(0, tf.shape(x)[0])

print(d1.numpy())

print(d2.numpy())

d3=tf.reshape(d2,shape = tf.shape(x)[:-1])

print(d3.numpy())
