How to Fix AttributeError: Module TensorFlow Has No Attribute Session Error

If you are working with TensorFlow, you may have encountered the error message "AttributeError: module 'tensorflow' has no attribute 'Session'". This error message can be frustrating, but it is not uncommon. In this guide, we will go through the reasons why this error can happen and provide you with a step-by-step solution to fix it.

Reasons for the Error

The "AttributeError: module 'tensorflow' has no attribute 'Session'" error message can occur due to the following reasons:

Using incompatible versions of TensorFlow: If you are using an incompatible version of TensorFlow, you may encounter this error message. For example, if you are using TensorFlow 2.x, you may need to use tf.compat.v1.Session() instead of tf.Session().

Incorrect import statement: If you have imported TensorFlow incorrectly, you may encounter this error message. Make sure you are importing TensorFlow correctly by using the following import statement: import tensorflow as tf.

Solution to the Error

To fix the "AttributeError: module 'tensorflow' has no attribute 'Session'" error message, follow the steps below:

1. Check your TensorFlow version: Check the version of TensorFlow you are using by running the following code:

import tensorflow as tf
print(tf.__version__)

If you are using TensorFlow 2.x, you may need to use tf.compat.v1.Session() instead of tf.Session().

1. Update your TensorFlow version: If you are using an outdated version of TensorFlow, upgrade to the latest version using the following command:

!pip install --upgrade tensorflow

1. Use the correct import statement: Make sure you are importing TensorFlow correctly by using the following import statement:

import tensorflow as tf

1. Use the correct syntax: If you are using TensorFlow 2.x, you may need to use tf.compat.v1.Session() instead of tf.Session(). Use the following code to create a session:

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()
sess = tf.Session()
