How do I use TensorFlow GPU version instead of CPU version in Python 3.6 x64?

import tensorflow as tf

Python is using my CPU for calculations. I can notice it because I have an error:

Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2

I have installed tensorflow and tensorflow-gpu.

How do I switch to GPU version?

Follow this tutorial Tensorflow GPU I did it and it works perfect.

Attention! - install version 9.0! newer version is not supported by Tensorflow-gpu


  1. Uninstall your old tensorflow
  2. Install tensorflow-gpu pip install tensorflow-gpu
  3. Install Nvidia Graphics Card & Drivers (you probably already have)
  4. Download & Install CUDA
  5. Download & Install cuDNN
  6. Verify by simple program

from tensorflow.python.client import device_lib print(device_lib.list_local_devices())

Use a GPU, These options are useful: Python's 'pip' installer is used at Step 7.2 of this guide to install Tensorflow. Additionally, I use the IDE (integrated� conda create --name tf_gpu tensorflow-gpu This is a shortcut for 3 commands, which you can execute separately if you want. Create an anaconda environment conda create --name tf_gpu. Activate the environment activate tf_gpu. Install tensorflow-GPU conda install tensorflow-gpu. You can use the conda environment.

First you need to install tensorflow-gpu, because this package is responsible for gpu computations. Also remember to run your code with environment variable CUDA_VISIBLE_DEVICES = 0 (or if you have multiple gpus, put their indices with comma). There might be some issues related to using gpu. if your tensorflow does not use gpu anyway, try this

GPU support, Get an introduction to GPUs, learn about GPUs in machine learning, learn the benefits of utilizing the GPU, and learn how to train TensorFlow� This is a multipurpose tutorial because not only we will install TensorFlow 2.0 with GPU but we will also set up our Nvidia GPU for OpenCV source installation so that we can use our GPU with the OpenCV DNN module. The Blog post for source installation of OpenCV in windows can be accessed here.

I tried following the above tutorial. Thing is tensorflow changes a lot and so do the NVIDIA versions needed for running on a GPU. The next issue is that your driver version determines your toolkit version etc. As of today this information about the software requirements should shed some light on how they interplay:

NVIDIA® GPU drivers —CUDA 9.0 requires 384.x or higher.
CUDA® Toolkit —TensorFlow supports CUDA 9.0.
CUPTI ships with the CUDA Toolkit.
cuDNN SDK (>= 7.2) Note: Make sure your GPU has compute compatibility >3.0
(Optional) NCCL 2.2 for multiple GPU support.
(Optional) TensorRT 4.0 to improve latency and throughput for inference on some models.

And here you'll find the up-to-date requirements stated by tensorflow (which will hopefully be updated by them on a regular basis).

Set Up Your GPU for Tensorflow, I walk through the steps to install the gpu version of TensorFlow for python on a windows 8 or Duration: 16:46 Posted: Dec 21, 2018 If you have Anaconda installed, then you can also create a python environment with the 3.6 version, if you do make sure to enable the environment before you proceed with the installation. We will use the TensorFlow ecosystem. This means we need to install the following libraries: CUDA 10.0; CuDNN 7.4; TensorFlow GPU built for these versions.

Strangely, even though the tensorflow website 1 mentions that CUDA 10.1 is compatible with tensorflow-gpu-1.13.1, it doesn't work so far. tensorflow-gpu gets installed properly though but it throws out weird errors when running.

So far, the best configuration to run tensorflow with GPU is CUDA 9.0 with tensorflow_gpu-1.12.0 under python3.6.

Following this configuration with the steps mentioned in (the answer above), worked for me :)

Installing Tensorflow with CUDA, cuDNN and GPU support on , In order to use the GPU version of TensorFlow, you will need an NVIDIA GPU with a compute Duration: 15:54 Posted: Aug 26, 2016 We'll use the same bit of code to test Jupyter/TensorFlow-GPU that we used on the commandline (mostly). Take the following snippet of code, and copy it into textbox (aka cell) on the page and then press Shift-Enter.

The 'new' way to install tensorflow GPU if you have Nvidia, is with Anaconda. Works on Windows too. With 1 line.

conda create --name tf_gpu tensorflow-gpu 

This is a shortcut for 3 commands, which you can execute separately if you want.

  1. Create an anaconda environment conda create --name tf_gpu

  2. Activate the environment activate tf_gpu

  3. Install tensorflow-GPU conda install tensorflow-gpu

You can use the conda environment.

How to Train TensorFlow Models Using GPUs, Reboot to let graphics driver take effect. 2. Install and test CUDA. To use� You can now run the following to get a notebook server running with GPU capabilities (note that we must run the jupyter in our virtualenv bin directory): ./bin/jupyter notebook. The trickiest part to configuring TensorFlow to run on the GPU was getting and installing the correct versions of key libraries.

How to Install TensorFlow GPU on Windows, Remember, every time you want to use this virtual environment, you must run this command! conda activate tf-gpu. 5. Install TensorFlow GPU� I am trying to install tensorflow-gpu in python, ubuntu 18.04, using pip command as pip install tensorflow-gpu==2.1.0 when I run this command: import tensorflow as tf I get following error: >&g

Installing the GPU version of TensorFlow for making use of your , Tensorflow model server (no batching, GPU): ~100ms per image; Not using GPUs/TPUs. GPUs made deep learning possible as they can do operations massively in parallel. When using docker containers to deploy deep learning models to production, the most examples do NOT utilize GPUs, they don’t even use GPU instances.

TensorFlow Framework & GPU Acceleration, These chips are designed to speed up model inference on mobile or edge devices and use less power than running inference on the CPU or GPU. Today, we are excited to announce a new TensorFlow Lite delegate that uses Apple's Core ML API to run floating-point models faster on iPhones and iPads with the Neural Engine.

  • Have you tried uninstalling tensorflow and just keep the tensorflow-gpu installed?
  • Try downloading CUDA and installing the GPU version.
  • That's just a warning, if you have an NVIDIA GPU, Tensorflow-gpu will automatically use that. To know more and how to disable the warning: To check that you're using the GPU: sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))
  • Device mapping: no known devices. I do not use Anaconda
  • NVIDIA 940mx, it is relative new Nvidia card. @JorgeLeitão yes, then I have no TensorFlow
  • So, CUDA 9.2 can be the problem? Should I install 9.0 then? Yesterday I had an error after installing CUDA 9.2. It said that I need DLL from CUDA 9.0 and I knew it was using GPU version, today all the time I see the error about CPU, so it is using CPU. I will try it step by step, thanks.
  • Yea, i had same problem about 2 month ago. I tried CUDA 9.1 and Tensorflow doesn't support it..Then i uninstall everything and repeat all steps with CUDA 9.0 and now it works without problems.
  • Maybe I should ask in another question, but is tensorflow on GPU is faster than CPU at your PC? I tried with linear regression model and for 10000 epos and step 0.01 my CPU can calculate it in 13 second and when I use GPU it takes 39 second.
  • Ofc i have CPU i7 8700k and GPU nVidia GTX 1060 STRING 6GB and on GPU is faster 20 times aproximate.
