How to Fix the “‘Module’ Object Has No Attribute ‘Placeholder'” Error in TensorFlow

This error message typically occurs when you’re trying to use TensorFlow 2.x code with TensorFlow 1.x. The Placeholder API was used in TensorFlow 1.x to define input placeholders, but it was removed in TensorFlow 2.x.

To resolve this issue, you can either:

1. Use TensorFlow 1.x and define your placeholders using tf.placeholder:

import tensorflow as tf

# Define a placeholder for input data
x = tf.placeholder(tf.float32, shape=[None, 784])

Use TensorFlow 2.x and define your inputs using tf.keras.layers.Input:

import tensorflow as tf

# Define a input layer for input data
inputs = tf.keras.layers.Input(shape=(784,))

Note that the rest of your code will need to be updated to use the appropriate API based on the version of TensorFlow you choose to use.
