Install on RHEL

This section describes how to install the Driverless AI Docker image on RHEL. The installation steps vary depending on whether your system has GPUs or if it is CPU only.

Environment

Operating System	GPUs?	Min Mem
RHEL with GPUs	Yes	64 GB
RHEL with CPUs	No	64 GB

For RHEL 8, Docker is not included and not supported by Red Hat (although it is still available from other sources). For more information, see https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/building_running_and_managing_containers/index.

Install on RHEL with GPUs

Note: Refer to the following links for more information about using RHEL with GPUs. These links describe how to disable automatic updates and specific package updates. This is necessary in order to prevent a mismatch between the NVIDIA driver and the kernel, which can lead to the GPUs failures.

Watch the installation video here. Note that some of the images in this video may change between releases, but the installation steps remain the same.

The following steps describe how to install the Driverless AI Docker image on RHEL version 7.4.

Open a Terminal and ssh to the machine that will run Driverless AI. Once you are logged in, perform the following steps.

1. Retrieve the Driverless AI Docker image from https://www.h2o.ai/download/.

2. Install and start Docker EE on RHEL (if not already installed). Follow the instructions on https://docs.docker.com/engine/installation/linux/docker-ee/rhel/.

Alternatively, you can run on Docker CE.

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum makecache fast
sudo yum -y install docker-ce
sudo systemctl start docker

3. Install nvidia-docker2 (if not already installed). More information is available at https://github.com/NVIDIA/nvidia-docker/blob/master/README.md.

curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | \
  sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | \
  sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt-get update

# Install nvidia-docker2 and reload the Docker daemon configuration
sudo apt-get install -y nvidia-docker2

Note: If you would like the nvidia-docker service to automatically start when the server is rebooted then run the following command. If you do not run this command, you will have to remember to start the nvidia-docker service manually; otherwise the GPUs will not appear as available.

sudo systemctl enable nvidia-docker

Alternatively, if you have installed Docker CE above you can install nvidia-docker with:

curl -s -L https://nvidia.github.io/nvidia-docker/centos7/x86_64/nvidia-docker.repo | \
sudo tee /etc/yum.repos.d/nvidia-docker.repo
sudo yum install nvidia-docker2

4. Verify that the NVIDIA driver is up and running. If the driver is not up and running, log on to http://www.nvidia.com/Download/index.aspx?lang=en-us to get the latest NVIDIA Tesla V/P/K series driver.

nvidia-docker run --rm nvidia/cuda nvidia-smi

5. Set up a directory for the version of Driverless AI on the host machine, replacing VERSION below with your Driverless AI Docker image version:

# Set up directory with the version name
mkdir dai_rel_VERSION

6. Change directories to the new folder, then load the Driverless AI Docker image inside the new directory. This example shows how to load Driverless AI. Replace VERSION with your image.

# cd into the new directory
cd dai_rel_VERSION

# Load the Driverless AI docker image
docker load < dai-docker-centos7-x86_64-VERSION.tar.gz

7. Enable persistence of the GPU. Note that this needs to be run once every reboot. Refer to the following for more information: http://docs.nvidia.com/deploy/driver-persistence/index.html.

sudo nvidia-persistenced --persistence-mode

8. Set up the data, log, and license directories on the host machine (within the new directory):

# Set up the data, log, license, and tmp directories on the host machine
mkdir data
mkdir log
mkdir license
mkdir tmp

9. At this point, you can copy data into the data directory on the host machine. The data will be visible inside the Docker container.

10. Run docker images to find the image tag.

11. Start the Driverless AI Docker image with nvidia-docker and replace TAG below with the image tag:

# Start the Driverless AI Docker image
nvidia-docker run \
    --pid=host \
    --init \
    --rm \
    --shm-size=256m \
    -u `id -u`:`id -g` \
    -p 12345:12345 \
    -v `pwd`/data:/data \
    -v `pwd`/log:/log \
    -v `pwd`/license:/license \
    -v `pwd`/tmp:/tmp \
    -v /etc/passwd:/etc/passwd:ro \
    -v /etc/group:/etc/group:ro \
    h2oai/dai-centos7-x86_64:TAG

Stopping the Docker Image

To stop the Driverless AI Docker image, type Ctrl + C in the Terminal (Mac OS X) or PowerShell (Windows 10) window that is running the Driverless AI Docker image.

Upgrading the Docker Image

This section provides instructions for upgrading Driverless AI versions that were installed in a Docker container. These steps ensure that existing experiments are saved.

WARNING: Experiments, MLIs, and MOJOs reside in the Driverless AI tmp directory and are not automatically upgraded when Driverless AI is upgraded.

• Build MLI models before upgrading.

• Build MOJO pipelines before upgrading.

• Stop Driverless AI and make a backup of your Driverless AI tmp directory before upgrading.

If you did not build MLI on a model before upgrading Driverless AI, then you will not be able to view MLI on that model after upgrading. Before upgrading, be sure to run MLI jobs on models that you want to continue to interpret in future releases. If that MLI job appears in the list of Interpreted Models in your current version, then it will be retained after upgrading.

If you did not build a MOJO pipeline on a model before upgrading Driverless AI, then you will not be able to build a MOJO pipeline on that model after upgrading. Before upgrading, be sure to build MOJO pipelines on all desired models and then back up your Driverless AI tmp directory.

Note: Stop Driverless AI if it is still running.

Requirements

As of 1.7.0, CUDA 9 is no longer supported. Your host environment must have CUDA 10.0 or later with NVIDIA drivers >= 410 installed (GPU only). Driverless AI ships with its own CUDA libraries, but the driver must exist in the host environment. Go to https://www.nvidia.com/Download/index.aspx to get the latest NVIDIA Tesla V/P/K series driver.

Upgrade Steps

1. SSH into the IP address of the machine that is running Driverless AI.

2. Set up a directory for the version of Driverless AI on the host machine:

# Set up directory with the version name
mkdir dai_rel_VERSION

# cd into the new directory
cd dai_rel_VERSION

3. Retrieve the Driverless AI package from https://www.h2o.ai/download/ and add it to the new directory.

4. Load the Driverless AI Docker image inside the new directory. This example shows how to load Driverless AI version. If necessary, replace VERSION with your image.

# Load the Driverless AI docker image
docker load < dai-docker-centos7-x86_64-VERSION.tar.gz

5. Copy the data, log, license, and tmp directories from the previous Driverless AI directory to the new Driverless AI directory:

# Copy the data, log, license, and tmp directories on the host machine
cp -a dai_rel_1.4.2/data dai_rel_VERSION/data
cp -a dai_rel_1.4.2/log dai_rel_VERSION/log
cp -a dai_rel_1.4.2/license dai_rel_VERSION/license
cp -a dai_rel_1.4.2/tmp dai_rel_VERSION/tmp

At this point, your experiments from the previous versions will be visible inside the Docker container.

6. Use docker images to find the new image tag.

7. Start the Driverless AI Docker image.

8. Connect to Driverless AI with your browser at http://Your-Driverless-AI-Host-Machine:12345.
