如何使用Keras Tensorflow删除张量中的最后一行和最后一列

import tensorflow as tf
from tensorflow import keras

tensor = tf.constant([[1, 2, 3], [4, 5, 6], [7, 8, 9]])

shape = tf.shape(tensor)

sliced_tensor = tensor[:shape[0]-1, :shape[1]-1]

import tensorflow as tf
from tensorflow import keras

tensor = tf.constant([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
shape = tf.shape(tensor)
sliced_tensor = tensor[:shape[0]-1, :shape[1]-1]

print(sliced_tensor)

tf.Tensor(
[[1 2]
 [4 5]], shape=(2, 2), dtype=int32)
