Tensorflow-gpu with Keras Error

Question

Using Ubuntu 16.04, PyCharm

I used the following link to install tensorflow-gpu with python 3.5 : http://www.python36.com/install-tensorflow141-gpu/

Tensorflow installation is fine. It ran with test code. Then I installed Keras to run codes from here: https://github.com/fchollet/deep-learning-with-python-notebooks/blob/master/5.1-introduction-to-convnets.ipynb

I got the following error:

2018-02-23 11:19:13.457201: I tensorflow/stream_executor/cuda/cuda_gpu_executor.cc:892] successful NUMA node read from SysFS had negative value (-1), but there must be at least one NUMA node, so returning NUMA node zero

Tensorflow-cpu works fine with Keras. My question is:

1) which instructions to follow to correctly install tensorflow-gpu with Keras for my setup?

2) What can I do eliminate these errors?

3) Is there any universal instructions that could be followed to correctly install tensorflow-gpu with Keras for all platforms?

Edit Here is a file I created which shows how to run Keras with tensorflow-gpu in Pycharm-community edition. https://github.com/mdkhan48/AgBot2018_VidStream/blob/master/how%20to%20run%20tensorflow-gpu.odt

There are 4 components you are trying to install:

Cuda
Cudnn
tensorflow
keras

they are not always synchronized, as of today tensorflow supports cuda 9.1 if you compile it yourself (like the guide you posted), the prebuilt binaries were compiled with cuda 9.0 and cudnn 7. I prefer using them so this is this is the cuda version I'm using.

this is how you can install it:

first, remove existing cuda installations:

sudo apt-get remove --purge nvidia-*

install ubuntu headers and cuda 9.0:

sudo apt-get install linux-headers-$(uname -r)
CUDA_REPO_PKG=cuda-repo-ubuntu1604_9.1.85-1_amd64.deb
wget -O /tmp/${CUDA_REPO_PKG} http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/${CUDA_REPO_PKG}
sudo dpkg -i /tmp/${CUDA_REPO_PKG}
sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/7fa2af80.pub
rm -f /tmp/${CUDA_REPO_PKG}
sudo apt-get update
sudo apt-get install -y cuda-9-0

download cuDNN v7.0.5 Library for Linux from nvidia site, navigate to downloaded folder and install it:

tar -xzvf cudnn-9.0-linux-x64-v7.tgz
sudo cp cuda/include/* /usr/local/cuda/include/
sudo cp cuda/lib64/* /usr/local/cuda/lib64/

reboot your machine and check nvidia driver works using:

nvidia-smi

the output should look like this:

create a virtual environment and install tensorflow and keras in it:

sudo apt-get install virtualenv
virtualenv tfenv
source tfenv/bin/activate
pip install tensorflow-gpu
pip install keras
