如何在TensorFlow中将张量转换为ndarray？

import tensorflow as tf
import numpy as np

# 创建一个张量
tensor = tf.constant([[1, 2, 3], [4, 5, 6]])

# 将张量转换为ndarray
ndarray = tensor.numpy()

print("Tensor:", tensor)
print("ndarray:", ndarray)

Tensor: tf.Tensor(
[[1 2 3]
 [4 5 6]], shape=(2, 3), dtype=int32)
ndarray: [[1 2 3]
 [4 5 6]]
