=New (by Wei and Minh): Tensorflow 1.9.0 with GPU Installation Log='''Important note: install '''<br> Install the version of software/packages strictly according to the instructions provided by Tensorflow. A different version of software, for example CUDA toolkit 9.2 instead of 9.0, might lead to failure in tensorflow.When upgrading tensorflow, do it very carefully. As of July 2018, Tensorflow is [https://github.com/tensorflow/tensorflow/issues/17629 notoriously easy to break] with careless installation. DO NOT attempt to install Tensorflow under your user account. Tensorflow has been installed for all users, and a new local install will interfere with it. ==Synopsis==Tensorflow was previously installed. In 2018 Summer, a new piece of graphics card was installed on DB Server. Wei and Minh hence-force installed and configured '''tensorflow-gpu 1.9.0 for Python3.6''' for all users of DB Server. ==Using Tensorflow==It is important to know that, on DB Server, Tensorflow-gpu 1.9.0 is installed for ''python3.6'', instead of either the default ''python3'' which is Python 3.5, or the default ''python' ' which is Python 2.7 . In case that the system default ''python3'' might be changed, type in terminal to find out: which python3and which python3.6  A quick test of whether tensorflow-gpu is working for ''python3.6'', type the following into a terminal: python3.6 -c "import tensorflow as tf; sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))" This will report back which CPU and GPU devices the tensorflow is using. If there is no information for the GPU device, there is something wrong. 
==NVIDIA configuration==
(In progress) Before installing tensorflow with GPU, configure the NVIDIA® software by following instruction: https://www.tensorflow.org/install/install_linux#NVIDIARequirements
===Install CUDA Toolkit 9.0===
*1. Installed CUDA Toolkit 9.0 Base Installer with the Runfile option. The toolkit is in
Add
export PATH=/usr/local/cuda-9.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64\ ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
Save and exit. Close and open the terminal (or source .bashrc).
nvcc -V

===Install cuDNN v7.1.4===
*5. Downloaded cuDNN v7.1.4 for CUDA 9.0:
So far it does not affect the functionality of tensorflow, but it will probably affect libcupti-dev library.
==Tensorflow (with GPU support) Installationin a virtual environment==To install tensorflow, follow We followed this instruction here: https://www.tensorflow.org/install/install_linux#InstallingVirtualenv and install tensorflow.===Install Tensorflow using the Virtual EnvironmentInstallation===
Install on DBServer under the user McNair. Password: askEd
*1.install virtualenv:
===Testing Tensorflow with GPU in virtual environment===
Create a python file with the following:
import tensorflow as tf
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))
Run it in the virtual environment.

==Installing Tensorflow with GPU support Installation as root for All users==
'''Important note: Currently on DB Server, pip/pip3 is working with Python3.6 rather than Python3. Hence the following installs a copy of tensorflow-gpu 1.9.0 for Python3.6 for all users'''
 
===Installation===
We followed instructions here: https://www.tensorflow.org/install/install_linux#InstallingNativePip
 
*0. Deleted previously installed tensorflow with CPU support:
sudo pip3 uninstall tensorflow
*1. Used this command to install tensorflow-gpu:
sudo pip3 install -U tensorflow-gpu
 
===Path variable (crucial)===
If you logged on as a user using tensorflow for the first time, you need to set the CUDA Toolkit 9.0 environment variables. Type into terminal
nano .bashrc
 
Add the following:
export PATH=/usr/local/cuda-9.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64\
${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
 
Save and exit (CTRL + O and CTRL + X). Type
source .bashrc
