tensorflow - 在 tensorflow 2.4 中被哪个命令 tf.placeholder 替换了？

Question

我正在使用tensorflow 2.4.1和来自tensorflow 1的代码。每当我运行以下命令时，都会出现错误

inputs = tf.placeholder(tf.int32, [None, None], name = 'input')

错误

AttributeError                            Traceback (most recent call last)
<ipython-input-14-c2404ca8696c> in <module>()
----> 1 inputs = tf.placeholder(tf.int32, [None, None], name = 'input')

AttributeError: module 'tensorflow' has no attribute 'placeholder'
