AttributeError module tensorflow has no attribute placeholder

This error occurs when you are trying to use the placeholder method in TensorFlow, but TensorFlow is not recognizing it as a valid method. This can happen if you are using an outdated version of TensorFlow, or if you have not imported the necessary modules.

To fix this error, you should make sure that you are using the latest version of TensorFlow and that you have imported the necessary modules. You can do this by adding the following 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 that TensorFlow recognizes the placeholder method. If this does not work, you may need to reinstall TensorFlow or update your Python environment.
