runtimeerror: cudnn error: cudnn_status_execution_failed

One of the often error message you might encounter is: runtimeerror: cudnn error: cudnn_status_execution_failed.

This error occurs if there is an issue with the cuDNN library, which is responsible for accelerating deep neural networks on NVIDIA GPUs.

Common Causes of the Error

The following are the common possible causes of the error:

  • Outdated cuDNN Library
  • Incompatible versions of cuDNN or CUDA
  • Insufficient GPU memory
  • Hardware issues

In addition, here are the other possible causes:

  1. issues with the Deep Learning framework
  2. malfunctioning GPU hardware
  3. conflicts with other software

How to Fix the Error?

Now that you already understand the common causes of “runtimeerror: cudnn error: cudnn_status_execution_failed“, let’s discuss how to fix it.

Here are the following steps to solve the error cudnn error: cudnn_status_execution_failed :

Method 1: Update cuDNN and CUDA

The first thing you should do is to make sure that you’re using compatible versions of cuDNN and CUDA with your deep learning framework.

If you are not sure which versions are compatible, check the documentation of your framework.

Method 2: Reduce the batch size

When you are working with large models or data sets that needed more memory than your GPU can produce.

You can try reducing the batch size. This will reduce the amount of memory needed to execute the model.

Method 3: Use a smaller model

If reducing the batch size doesn’t work, you can try using a smaller model that needs less memory to execute.

This will be not an ideal solution if you need to work with large models, but it can be a temporary solutions.

Method 4: Upgrade your GPU

If you are working with large models or data sets that needed more memory than your GPU can produce, you must upgrade your GPU to a more powerful one that can manage the workload.

Method 5: Check for other hardware issues

If you think that hardware issues are causing the error, you need to run diagnostic tests to analyze the issue.

Check your GPU, power supply, and other hardware components for defects or compatibility issues.

Tips to Avoid the Error

The following are the tips to avoid the error:

  • Keeping cuDNN and CUDA versions up to date
  • Using compatible GPU hardware
  • Monitoring GPU memory usage

Here are the other tips to prevent this error:

  • Use a batch size that is appropriate for your GPU memory
  • Use smaller models if possible
  • Avoid using multiple Deep Learning frameworks simultaneously
  • Regularly check for updates and patches to the Deep Learning framework, cuDNN Library, and CUDA.


What is cuDNN?

cuDNN is a library created by NVIDIA that provides GPU acceleration for deep learning computations. It is generally used in popular deep learning frameworks such as TensorFlow, PyTorch, and Caffe.

How do I check the version of cuDNN and CUDA?

You can check the version of cuDNN and CUDA by running the following commands in your terminal:
cat /usr/local/cuda/version.txt
cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

How do I upgrade my GPU?

To upgrade your GPU, you will need to purchase a new one that is compatible with your system. Make sure that your power supply is sufficient to support the new GPU.

What is the “runtimeerror: cudnn error: cudnn_status_execution_failed” error?

The “cudnn error: cudnn_status_execution_failed” is an error that occurs when using the NVIDIA cuDNN Library for Deep Learning on a GPU. It indicates that there was an error in executing the computations using the cuDNN Library.
