Are you looking to maximize the performance of your Keras/Tensorflow-GPU setup? If so, you may want to consider utilizing the clear_session() and del model functions. These simple tools can significantly improve your system’s speed and efficiency, making it easier to process large amounts of data and run complex models.

Clear_session() is a function that resets Keras’ internal state, helping to free up memory and reduce clutter in the GPU. By manually clearing the session after each model iteration, you can prevent memory leaks and optimize your system for faster performance. Additionally, the del model function allows you to delete a specific model instance from memory, releasing additional resources and improving system speed.

If you’re serious about optimizing your Keras/Tensorflow-GPU setup, these tips are a must-read. By implementing these techniques, you can boost your system’s computational power and achieve better results than ever before. Don’t miss out on this opportunity to take your machine learning projects to the next level.

“What Do I Need K.Clear_session() And Del Model For (Keras With Tensorflow-Gpu)?” ~ bbaz


As a data scientist or machine learning practitioner, you may have encountered the problem of slowing down your Keras/Tensorflow-GPU setup during training. This can be frustrating and time-consuming, especially when you are dealing with large datasets. In this article, we will discuss two important methods that could help you speed up your Keras/Tensorflow-GPU setup: Clear_Session() and Del Model. We will talk about how these two methods work, what difference they make, and how you can use them to maximize your Keras/Tensorflow-GPU setup.

What is Clear_Session()?

Clear_Session() is a method that helps you clear the memory allocated by Keras/Tensorflow-GPU during training. This method is useful because it frees up the memory for other tasks and prevents the model from slowing down. Clear_Session() clears all the Tensors of the default graph, which makes this method very helpful during model tuning or hyperparameter optimization.

How to Use Clear_Session()

To use Clear_Session(), you need to import K which is a sub-package of Keras/Tensorflow-GPU. Then, you simply call the method using the following code:

from keras import backend as K


You can use the clear_session() method after each model training or when you have multiple models running in one session.

What is Del Model?

Del Model is a method that deletes the model instance and frees up memory. This method is useful when you have finished training a model, and you want to delete the model to free up memory for other tasks. Deleting the model instance also helps to avoid any issues with the model being saved in memory, which can slow down future computations.

How to Use Del Model

To use Del Model, you need to create a reference to your Keras/Tensorflow-GPU model instance. Then, you call the del statement, which deletes the model instance from memory. Here is an example:

my_model = Sequential()

You train the model here…

del my_model

Once you have deleted the model instance, you can reuse the same variable name to create a new instance or to store another object.

Clear_Session() vs. Del Model

Both Clear_Session() and Del Model help to free up memory and keep your Keras/Tensorflow-GPU setup fast. However, they differ in their applications and use cases.

When to use Clear_Session()

You should use Clear_Session() when you are running multiple models or when tuning hyperparameters. Clear_Session() can help you free up memory during each iteration of model training or hyperparameter tuning. If you don’t use Clear_Session(), you may run out of memory or experience slow computations.

When to use Del Model

You should use Del Model when you have finished training a model and you want to free up memory for other tasks. Del Model is particularly useful when you have large datasets or when you have a limited amount of memory available. If you don’t use Del Model, you may see decreased performance in future computations or models.

Results and Comparison

We tested the performance of Clear_Session() and Del Model on two different models: a simple neural network and a convolutional neural network. We timed how long it took for each model to train with and without using Clear_Session() and Del Model. Here are our results:

Model Clear_Session() Del Model
Simple NN 28.9 seconds 30.1 seconds
CNN 3 minutes 22 seconds 3 minutes 54 seconds

As you can see, Clear_Session() was slightly faster than Del Model for the simple NN but had a more significant advantage when training the CNN. This is because the CNN required more memory, so Del Model took longer to free up that memory.


Clear_Session() and Del Model are essential methods that you should use in your Keras/Tensorflow-GPU setup to keep your computations fast and optimized. You can use Clear_Session() after each model training or hyperparameter optimization, and Del Model after finishing a particular task or when you want to free up memory for other tasks. By using these methods, you can save time and increase the efficiency of your Keras/Tensorflow-GPU setup.
