Install neurodesktop on Linux

Minimum System Requirements

At least 3GB free space for neurodesktop base image
Docker requirements. Details found under https://docs.docker.com/get-docker/

Quickstart

1. Install Docker/Podman

Install Docker from here: https://docs.docker.com/get-docker/. Additional information available below. Neurodesk also works with Podman.

2. Run Neurodesktop

Before the first run, create a local folder where the downloaded applications will be stored, e.g. ~/neurodesktop-storage

Then use one of the following options to run Neurodesktop:

Option 1 (Recommended): Neurodesk-App

Instructions on installing and using the app: https://www.neurodesk.org/docs/getting-started/neurodesktop/neurodeskapp/

Option 2 (Advanced): Using Terminal

Open a terminal, and type the following command to automatically download the neurodesktop container and run it

sudo docker run \
  --shm-size=1gb -it --privileged --user=root --name neurodesktop \
  -v ~/neurodesktop-storage:/neurodesktop-storage \
  -e NB_UID="$(id -u)" -e NB_GID="$(id -g)" \
  -p 8888:8888 \
  -e NEURODESKTOP_VERSION=2023-09-20 vnmd/neurodesktop:2023-09-20

If you get errors in neurodesktop then check if the ~/neurodesktop-storage directory is writable to all users. Otherwise run:

chmod a+rwx ~/neurodesktop-storage

Once neurodesktop is downloaded, leave the terminal open and check which server neurodesktop is running on (Avoid pressing CTRL+C).

To access neurodesktop, open your web browser and type in one of the provided URLs in your terminal (e.g. http://127.0.0.1:8888/lab?token=your_unique_token).

If using Chrome, a pop-up may open with the text:

"http://127.0.0.1:8888 wants to
See text and images copied to the clipboard".

Press “Allow” to access your clipboard from within Neurodesktop.

If using Firefox, you might not be able to paste clipboard content into the virtual desktop from the host computer. In that case, please follow these instructions

Press on “Desktop Auto-Resolution” under “ALL CONNECTIONS”
If it is the first time you have used Neurodesktop, wait until the desktop appears (it may take a few seconds). Otherwise, it should appear instantaneously.
Neurodesk is now ready to use! See the tutorials page for advice on how to use Neurodesk.
For an optimal experience, switch your browser to full-screen mode by following the instructions for your browser here: https://www.thewindowsclub.com/open-chrome-edge-or-firefox-browser-in-full-screen-mode

The browser can be closed anytime, and Neurodesktop will continue running in the background. To reconnect to Neurodesktop, simply start over from step 3 above.

Deleting neurodesktop:

When done processing your data it is important to stop and remove the container - otherwise the next start or container update will give an error ("… The container name “/neurodesktop” is already in use…")

Note

Notice that any data that were saved outside of /neurodesktop-storage would be lost. Please make sure to move all your data to that folder before deleting neurodesktop.

Click on the terminal from which you ran neurodesktop
Press Ctrl-C
Run:

docker stop neurodesktop

Run:

docker rm neurodesktop

Installing Docker

For general installation instructions, refer to https://docs.docker.com/get-docker/

RHEL/CentOS (yum-based)

Refer to https://docs.docker.com/engine/install/centos/

One example to install docker in a yum-based distribution could look like this:

sudo dnf install -y yum-utils 
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo dnf install docker-ce docker-ce-cli containerd.io
# or if dnf not found: sudo yum install docker-ce docker-ce-cli containerd.io
sudo systemctl enable docker
sudo systemctl start docker
sudo docker version
sudo docker info
sudo groupadd docker
sudo usermod -aG docker $USER
sudo chown root:docker /var/run/docker.sock
newgrp docker

Ubuntu/Debian (apt-based)

Refer to https://docs.docker.com/engine/install/ubuntu/

One example to install docker in a apt-based distribution could look like this:

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io

GPU support

RHEL/CentOS (yum-based)

sudo yum install nvidia-container-toolkit -y

Running neurodesktop container with GPU

sudo docker run \
  --shm-size=1gb -it --privileged --user=root --name neurodesktop \
  -v ~/neurodesktop-storage:/neurodesktop-storage \
  -e NB_UID="$(id -u)" -e NB_GID="$(id -g)" \
  --gpus all \
  -p 8888:8888 -e NEURODESKTOP_VERSION=2023-09-20 \
  vnmd/neurodesktop:2023-09-20

Running tensorflow (w/ GPU)

Using tensorflow (python)

conda install tensorflow-gpu
python

import tensorflow as tf
print("Num GPUs Available: ", len(tf.config.list_physical_devices('GPU')))

Using tensorflow (singularity container in neurodesktop)

singularity pull docker://tensorflow/tensorflow:latest-gpu
singularity run --nv tensorflow_latest-gpu.sif
python

import tensorflow as tf
print("Num GPUs Available: ", len(tf.config.list_physical_devices('GPU')))

Using an RDP Client

Startup Neurodesktop using the following command:

sudo docker run \
  --shm-size=1gb -it --privileged --user=root --name neurodesktop \
  -v ~/neurodesktop-storage:/neurodesktop-storage \
  -e NB_UID="$(id -u)" -e NB_GID="$(id -g)" \
  -p 8888:8888 -p 3390:3389 \
  -e NEURODESKTOP_VERSION=2023-09-20 vnmd/neurodesktop:2023-09-20

If you want to connect via RDP using a different port, replace 3390 in the previous and next step with your port

Open your RDP client and connect to Computer localhost:3390

Use the following details to login if prompted

username: user
password: password

Using VNC

To enable VNC and disable RDP, startup Neurodesktop using the following command:

sudo docker run \
  --shm-size=1gb -it --privileged --user=root --name neurodesktop \
  -v ~/neurodesktop-storage:/neurodesktop-storage \
  -e NB_UID="$(id -u)" -e NB_GID="$(id -g)" \
  -p 8888:8888 \
  -e NEURODESKTOP_VERSION=2023-09-20 vnmd/neurodesktop:2023-09-20 --vnc

To enable both VNC and RDP, startup Neurodesktop using the following command:

sudo docker run \
  --shm-size=1gb -it --privileged --user=root --name neurodesktop \
  -v ~/neurodesktop-storage:/neurodesktop-storage \
  -e NB_UID="$(id -u)" -e NB_GID="$(id -g)" \
  -p 8888:8888 \
  -e NEURODESKTOP_VERSION=2023-09-20 vnmd/neurodesktop:2023-09-20 --vnc --rdp

VNC allows for multiple desktop connections to same instance

VNC option for Neurodesktop on the browser does not support auto-resolution

Using a VNC Client

Startup Neurodesktop using the following command:

sudo docker run \
  --shm-size=1gb -it --privileged --user=root --name neurodesktop \
  -v ~/neurodesktop-storage:/neurodesktop-storage \
  -e NB_UID="$(id -u)" -e NB_GID="$(id -g)" \
  -p 8888:8888 -p 5901:5901 \
  -e NEURODESKTOP_VERSION=2023-09-20 vnmd/neurodesktop:2023-09-20 --vnc
