TensorFlow Check: How to See if Your System Has an Available GPU

If you’re running TensorFlow on a system with an available GPU, you can speed up your computations by taking advantage of it. But how can you check if your system has an available GPU?

Introduction

GPUs are specialized hardware designed to accelerate certain types of computations, typically those involving massive parallelism. In recent years, they’ve become increasingly important for deep learning, since many popular neural network architectures are particularly well suited to the kind of large-scale matrix operations that GPUs can perform very efficiently.

If you’re planning on doing any deep learning with TensorFlow, it’s important to know whether or not your system has an available GPU. In this post, we’ll show you how to check if your system has an available GPU and how to use it with TensorFlow.

What is TensorFlow?

TensorFlow is a powerful tool for machine learning. It takes advantage of GPUs (graphical processing units) to speed up calculations. To see if your system has an available GPU, you can check the TensorFlow website.

What are the requirements for TensorFlow?

TensorFlow is a powerful tool for machine learning, but it can be daunting to set up on your own machine. This guide will show you how to see if your system has an available GPU that can be used with TensorFlow.

GPUs can dramatically speed up the training of deep neural networks. TensorFlow is designed to take advantage of this by providing high-performance APIs that can be used to train models on GPUs. However, not all systems have a GPU that can be used with TensorFlow.

To see if your system has an available GPU, you can use the nvidia-smi command:

nvidia-smi

If you see something like the following output, then your system has an NVIDIA GPU that can be used with TensorFlow:

+—————————————————————————–+
| NVIDIA-SMI 418.56 Driver Version: 418.56 CUDA Version: 10.1 |
|——————————-+———————-+———————-+
|GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr. ECC |
| Fan Temp Perf Pwr:Usage/Cap| Memory-Usage | GPU-Util Compute M. |
|===============================+======================+======================|
|| 0 GeForce GTX 1080 Off | 00000000:01:00.0 Off | N/A |”

How to see if your system has an available GPU

You can check whether your system has an available GPU by opening a Python shell and running the following command:

import tensorflow as tf
tf.test.gpu_device_name()

If the output is “/device:GPU:0”, then your system has an available GPU.

What are the benefits of using TensorFlow with a GPU?

The benefits of using TensorFlow with a GPU are mainly speed and efficiency. GPUs are much faster than CPUs when it comes to matrix operations, which is what TensorFlow heavily relies on. This means that your training will progress much faster if you use a GPU. In addition, GPUs are more energy efficient than CPUs, so you’ll save on power consumption as well.

How to install TensorFlow with a GPU

TensorFlow is a free and open-source software library for data analysis and machine learning. In this guide, we’ll show you how to install TensorFlow on a GPU-powered system.

GPUs are used in parallel computing and are more effective than CPUs for certain types of tasks. TensorFlow is designed to take advantage of GPUs in order to accelerate the performance of its computations.

In order to use a GPU with TensorFlow, you will need to install the library on a system that has a supported GPU. NVIDIA GPUs are the most widely used type of GPU for deep learning and TensorFlow supports them out of the box.

If you don’t have a NVIDIA GPU, you can still use TensorFlow with a CPU-only setup. However, you won’t be able to take advantage of the accelerated performance that a GPU provides.

Installing TensorFlow with a GPU can be done either using pre-built binaries or from source. We’ll show you how to do both in this guide.

How to use TensorFlow with a GPU

If you’re running TensorFlow on a system with an available GPU, you can use the GPU for computation. GPUs are significantly faster than CPUs for certain types of computation, so using a GPU can greatly speed up your training.

To see if your system has an available GPU, open a terminal and enter the following command:

nvidia-smi

You should see output similar to the following:

+—————————————————————————–+
| NVIDIA-SMI 367.57 Driver Version: 367.57 |
|——————————-+———————-+———————-+
| GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr. ECC |
| Fan Temp Perf Pwr:Usage/Cap| Memory-Usage | GPU-Util Compute M. |
|===============================+======================+======================|
| 0 GeForce GTX 1080 On | 0000:01:00.0 Off | N/A |
| 67% 36C P2 97W / 250W | 1MiB / 8119MiB | 0% Default | +——————————-+———————-+———————-+

Troubleshooting

If you’re new to TensorFlow, we recommend starting with the low-level API. It’s easier to understand and debug, and can give you more control over how you structure your model. The higher-level API is built on top of the lower-level API and is designed to make common tasks easier and faster.

If you’re using a GPU with TensorFlow, you’ll need to install the GPU version of TensorFlow. You can do this using pip:

pip install tensorflow-gpu

If your system doesn’t have a GPU, you can still use TensorFlow, but you’ll need to install the CPU version of TensorFlow:

pip install tensorflow

Conclusion

If you have a supported NVIDIA GPU on your system, you can use TensorFlow to take advantage of it. In order to do so, you’ll need to install the NVIDIA CUDA Toolkit. With the CUDA Toolkit installed, you can then install TensorFlow. Finally, you can use TensorFlow to check if your system has an available GPU.
