Docker Environment for DeepLabCut2.0+

This package will allow you to run DeepLabCut2.x with everything pre-installed inside a Docker container. This base container is mainly useful for server deployment for training networks and video analysis (i.e. you can move this to your server, University Cluster, AWS, etc) as it assumes you have no display.

However, if you want to use the GUIs, there is a "heavy" image (16 GB) that eqs built from our original container. It is a folder inside this repo as "GUISupport_DLCDocker", but also please see here for more information.

This Docker file is based off the Bethge lab container. Specifically, the one we provide comes with Ubuntu 16.04 + CUDA 9.0 + CuDNN v7 and Tensorflow 1.8 and the required python packages.

Note, please check your NVIDIA driver is up to date (for CUDA9 you need > 384.xx). Please check your driver/CUDA/TensorFlow version on this Stackoverflow post.

NOTE: this container does not work on windows hosts!

Prerequisites

(1) Install Docker. See https://docs.docker.com/install/ & for Ubuntu: https://docs.docker.com/install/linux/docker-ce/ubuntu/ Test docker:

$ sudo docker run hello-world

The output should be: Hello from Docker! This message shows that your installation appears to be working correctly.

(2) Install nvidia-docker, see https://nvidia.github.io/nvidia-docker/. But, basically it is just:

$ sudo apt-get install nvidia-docker2

*you can also run: sudo docker run --runtime=nvidia --rm nvidia/cuda:9.0-base nvidia-smi to test your nvidia-docker, and if you get the error docker: Error response from daemon: Unknown runtime specified nvidia. just simply restart docker:

   $ sudo systemctl daemon-reload
   $ sudo systemctl restart docker

(3) Add your user to the docker group (https://docs.docker.com/install/linux/linux-postinstall/#manage-docker-as-a-non-root-user) Quick guide to create the docker group and add your user: Create the docker group.

$ sudo groupadd docker

Add your user to the docker group.

$ sudo usermod -aG docker $USER

(perhaps restart or (at min) open a new terminal to make sure that you are added from now on) Lastly, download this Docker:

git clone https://github.com/DeepLabCut/Docker4DeepLabCut2.0
cd Docker4DeepLabCut2.0

Step-by-step instructions for creating the Docker environment:

Next create the image. The image needs only be created once to use the commands below (i.e. you can enter, stop and re-enter a container again). However, if you want to UPGRADE YOUR DEEPLABCUT package, you should build a new image! All the required software will be downloaded from DockerHub. (you can pick a user name and container name other than dlc_username/dlcdocker if you want):

docker image build -t dlc_username/dlcdocker .

Starting the docker container from your image (de-novo):

In the terminal start your container with the following command (in the DockerContainer4DeepLabCut2.0 folder):

Options:

• change port: (i.e. 2351 can be 777, etc)
• change which GPU to use (check which GPU you want to use in the terminal by running nvidia-smi)
• change the name: --name containername can be anything you want
• change the home folder:-e USER_HOME=$HOME/DeepLabCut (i.e. this can be -e USER_HOME=$HOME/whateveryouwant)

GPU=1 bash ./dlc-docker run -d -p 2351:8888 -e USER_HOME=$HOME/DeepLabCut --name containername dlc_username/dlcdocker

Do not run this with sudo.

• Enter the container via the terminal (to get terminal access in container):

docker exec --user $USER -it containername /bin/bash

Access your linked (internal home) directory:

cd ../../../home/

Now, for the training and video analysis you need to supress the GUI support:

Linux: export DLClight=True

Now you have an Ubuntu with Python3 and a GPU-installed with Tensorflow 1.8, and all the other dependencies ... installed! Happy DeepLabCutting!

Jupyter + Docker:

This container could also be used for other things besides DeepLabCut, so you might want to utlitize the features in Jupyter, i.e. you can also go into the terminal separately via a browser interface (i.e Google Chrome + a Jupyter Notebook) to check out what's inside. For this, go to the port you specified, i.e. in our example enter http://localhost:2351 in Google Chrome. Get the token for entry: back in the terminal, look at the docker log; copy and paste the value after "token=":

$ docker logs containername 

Then, you can open the notebook provided, to check your installation and play around with other ways this Docker could be useful to you.

Using the Docker for Training and Video Analysis:

Here is an example Notebook for using DeepLabCut with Jupyter: https://github.com/AlexEMG/DeepLabCut/blob/master/examples/Docker_TrainNetwork_VideoAnalysis.ipynb

Docker Quick Tips:

Check which containers are running:

$ docker ps 

You can stop a container:

$ docker stop containername 

You can re-start your container:

$ docker start containername

After stopping you can remove old containers:

$ docker rm containername

(once removed, it can be created again):

GPU=1 bash ./dlc-docker run -d -p 2351:8888 -e USER_HOME=$HOME/DeepLabCut --name containername dlc_username/dlcdocker
