A Linux server with an NVIDIA GPU. These instructions were written using CentOS 7; Ubuntu 14.04 or later is known to work as well, though installation instructions may differ.
Dataiku DSS installed
We aim to install the following Python libraries:
Keras 1.2.2 (version required in fast.ai)
To do so, we must install:
Install NVIDIA driver and the CUDA and cuDNN libraries
Install NVIDIA driver
Before installing the driver we need to install required libraries, using the yum package-management utility shipped with CentOS:
sudo yum update
sudo yum install kernel-devel kernel-headers gcc gcc-c++ make wget epel-release dkms libstdc++.i686 bzip2 python-pip
The new kernel should now be loaded. You can verify that your kernel is the same as the installed source by comparing the results of the following two commands:
rpm -q kernel-devel
If the version numbers are not the same, you can upgrade and reboot:
sudo yum -y upgrade kernel kernel-devel
By default, CentOS comes with a "nouveau" driver for the GPU. You can verify it with the command
lsmod | grep nouv
We need to blacklist this driver in order to let the GPU use NVIDIA. Hence, you need to create a file at: /etc/modprobe.d/blacklist-nouveau.conf, containing:
options nouveau modeset=0
To enforce the blacklist, run the commands
sudo dracut --force
You can verify that the driver is not used anymore by re-running the command lsmod | grep nouv, which should not display anything this time.
We can now install the NVIDIA driver with its official runfile. You need to download the appropriate runfile from the NVIDIA website. Be careful to take NVIDIA for CUDA 8.0, which is the last supported version of CUDA for Tensorflow.
For our instance, it was the following parameters:
...and can be downloaded with the following command:
First make the file executable (the filename may be slightly different according to the version you have downloaded):
sudo chmod +x NVIDIA-Linux-x86_64-384.66.run
Then execute it:
Follow the instructions in the command line installation interface, using default options.
NVIDIA drivers are now installed! You can check that it worked by running the command nvidia-smi. That should display something like:
Install the CUDA library
First you need to download the CUDA toolkit. You want to install CUDA 8.0, and make the appropriate selections for your platform:
Select the runfile installer. For our instance, the link is:
As before, you need to make the file executable:
sudo chmod +x cuda_8.0.61_375.26_linux-run
Then run this command to retrieve the installer:
sudo ./cuda_8.0.61_375.26_linux-run --extract=$HOME
Next, find the installer (it starts with "cuda-linux64-rel") and run it:
Then follow the installation steps, using default options. Remember to say yes to the question "Would you like to add desktop menu shortcuts?".
Finally, you need to add CUDA to the PATH and create LD_LIBRARY_PATH. To do so, add the following line to your ~/.bashrc:
Be sure to run source ~/.bashrc afterward, or to reboot your instance so that your changes are taken into account.
You can check that CUDA is installed by running the command nvcc --version.
Installing the cuDNN library
First register as a member of the NVIDIA developer program.
Then download cuDNN 6.0 for CUDA 8.0 for Linux:
Then, transfer it to your instance, for instance using:
scp -i <MY_PRIVATE_KEY_FILE> <PATH_TO_CUDNN_ARCHIVE> centos@<MY_PUBLIC_DNS_IPV4>:~
Decompress the file:
tar -xzf cudnn-8.0-linux-x64-v6.0.tgz
Then copy/paste the library to your CUDA installation directory. Go to the CUDA folder created at the previous step and run the commands:
cp include/cudnn.h /usr/local/cuda/include/
cp lib64/libcudnn* /usr/local/cuda/lib64/
cuDNN is now installed!
Set Up A Deep Learning Code Environment in Dataiku DSS
If you plan to use the Deep Learning for Images plugin, follow the instructions in the Howto for installing the plugin and it will set up its own code environment.
To create a custom code environment, follow the reference documentation to create a Python environment and install the following libraries (note the following copy and paste-able text assumes you are using conda):
Now you can use your environment from a notebook in your own DSS project.
You can test tensorflow-gpu from your notebook:
from tensorflow.python.client import device_lib
It should give you a message like this:
If any GPU is listed, it means that you can use it with tensorflow. Congratulations!
Hi is there an updated guide for CUDA 9.0/cuDNN 7.0 or will this guide just work on those versions fine? Thanks!
PS: I am on RHEL 7 so I presume the above should work fine as CentOS 7 is the open source equivalent.
@Turribeach Thanks for your follow up. This depends:
In regards to Alex's directions above, they are mostly still valid except the following:
I hope this helps!
