TensorFlow 'placeholder' Attribute Error: How to Fix

This error occurs when you try to use the 'placeholder' method in TensorFlow, but TensorFlow doesn't recognize it as a valid method. This can happen if you're using an outdated version of TensorFlow, or if you haven't imported the necessary modules.

To fix this error, make sure you're using the latest version of TensorFlow and that you've imported the necessary modules. Add these lines of code at the beginning of your script:

import tensorflow as tf

tf.compat.v1.disable_eager_execution()

This will disable the eager execution mode and ensure TensorFlow recognizes the 'placeholder' method. If this doesn't work, you might need to reinstall TensorFlow or update your Python environment.
