Introducing Deepo

02 Jan 2018

Given the current state of deep learning research and development, we may need to play around with different frameworks (e.g., PyTorch for research and fun, Caffe2 for edge device inference, etc). However, setting up all the deep learning frameworks to coexist and function correctly is tedious and time-consuming.

So I made Deepo, which contains a series of Docker images that

and their Dockerfile generator that

Quick Start

GPU Version

Installation

Step 1. Install Docker and nvidia-docker.

Step 2. Obtain the all-in-one image from Docker Hub

docker pull ufoym/deepo

Usage

Now you can try this command:

nvidia-docker run --rm ufoym/deepo nvidia-smi

This should work and enables Deepo to use the GPU from inside a docker container. If this does not work, search the issues section on the nvidia-docker GitHub – many solutions are already documented. To get an interactive shell to a container that will not be automatically deleted after you exit do

nvidia-docker run -it ufoym/deepo bash

If you want to share your data and configurations between the host (your machine or VM) and the container in which you are using Deepo, use the -v option, e.g.

nvidia-docker run -it -v /host/data:/data -v /host/config:/config ufoym/deepo bash

This will make /host/data from the host visible as /data in the container, and /host/config as /config. Such isolation reduces the chances of your containerized experiments overwriting or using wrong data.

Please note that some frameworks (e.g. PyTorch) use shared memory to share data between processes, so if multiprocessing is used the default shared memory segment size that container runs with is not enough, and you should increase shared memory size either with --ipc=host or --shm-size command line options to nvidia-docker run.

nvidia-docker run -it --ipc=host ufoym/deepo bash

CPU Version

Installation

Step 1. Install Docker.

Step 2. Obtain the all-in-one image from Docker Hub

docker pull ufoym/deepo:cpu

Usage

Now you can try this command:

docker run -it ufoym/deepo:cpu bash

If you want to share your data and configurations between the host (your machine or VM) and the container in which you are using Deepo, use the -v option, e.g.

docker run -it -v /host/data:/data -v /host/config:/config ufoym/deepo:cpu bash

This will make /host/data from the host visible as /data in the container, and /host/config as /config. Such isolation reduces the chances of your containerized experiments overwriting or using wrong data.

Please note that some frameworks (e.g. PyTorch) use shared memory to share data between processes, so if multiprocessing is used the default shared memory segment size that container runs with is not enough, and you should increase shared memory size either with --ipc=host or --shm-size command line options to docker run.

docker run -it --ipc=host ufoym/deepo:cpu bash

You are now ready to begin your journey.

Customization

Note that docker pull ufoym/deepo mentioned in Quick Start will give you a standard image containing all available deep learning frameworks. You can customize your own environment as well.

Unhappy with all-in-one solution?

If you prefer a specific framework rather than an all-in-one image, just append a tag with the name of the framework. Take tensorflow for example:

docker pull ufoym/deepo:tensorflow

Other python versions

Note that all python-related images use Python 3.6 by default. If you are unhappy with Python 3.6, you can also specify other python versions:

docker pull ufoym/deepo:py27

docker pull ufoym/deepo:tensorflow-py27

Currently, we support Python 2.7 and Python 3.6.

See Available Tags for a complete list of all available tags. These pre-built images are all built from docker/Dockerfile.* and circle.yml. See How to generate docker/Dockerfile.* and circle.yml if you are interested in how these files are generated.

Jupyter support

Step 1. pull the image with jupyter support

docker pull ufoym/deepo:all-py36-jupyter

Note that the tag could be either of all-py36-jupyter, py36-jupyter, all-py27-jupyter, or py27-jupyter.

Step 2. run the image

nvidia-docker run -it -p 8888:8888 ufoym/deepo:all-py36-jupyter jupyter notebook --no-browser --ip=0.0.0.0 --allow-root --NotebookApp.token= --notebook-dir='/root'

Build your own customized image with Lego-like modules

Step 1. prepare generator

git clone https://github.com/ufoym/deepo.git
cd deepo/generator
pip install -r requirements.txt

Step 2. generate your customized Dockerfile

For example, if you like pytorch and lasagne, then

python generate.py Dockerfile pytorch lasagne

This should generate a Dockerfile that contains everything for building pytorch and lasagne. Note that the generator can handle automatic dependency processing and topologically sort the lists. So you don’t need to worry about missing dependencies and the list order.

You can also specify the version of Python:

python generate.py Dockerfile pytorch lasagne python==3.6

Step 3. build your Dockerfile

docker build -t my/deepo .

This may take several minutes as it compiles a few libraries from scratch.
