如何在不使用会话的情况下从tf.size()获取int值

import tensorflow as tf

# 开启Eager Execution模式
tf.enable_eager_execution()

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

# 获取张量的大小并转换为int值
size = int(tf.size(tensor))

print(size)

import tensorflow as tf
import numpy as np

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

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

# 获取数组的大小并转换为int值
size = int(np.size(array))

print(size)
