无法在keras中生成张量板

import tensorflow as tf

# 创建一个4x4的张量
tensor = tf.constant([[1, 2, 3, 4],
                      [5, 6, 7, 8],
                      [9, 10, 11, 12],
                      [13, 14, 15, 16]])

# 在行和列上复制张量
tiled_tensor = tf.tile(tensor, multiples=[2, 2])

# 打印结果
print(tiled_tensor)

import torch

# 创建一个4x4的张量
tensor = torch.tensor([[1, 2, 3, 4],
                       [5, 6, 7, 8],
                       [9, 10, 11, 12],
                       [13, 14, 15, 16]])

# 在行和列上复制张量
tiled_tensor = tensor.repeat(2, 2)

# 打印结果
print(tiled_tensor)
