aeon is Intel Nervana's framework-independent deep learning dataloader committed to best performance. Designed for ease-of-use and extensibility.

  • Supports common media types: image, video, audio. It is ready for use with classification, segmentation, localization, transcription and more.
  • Loads and augments data in parallel to framework computation.
  • Examples folder contains simple scripts showing how to use it.

For fast iteration and model exploration, it is already used by fastest performance deep learning framework neon.

See the new features in our latest release.

Getting Started


First grab Aeon's dependencies:

Ubuntu (release 16.04 LTS and later):

apt-get install git clang libcurl4-openssl-dev libopencv-dev libsox-dev libboost-filesystem-dev libboost-system-dev libssl-dev
For Python 3.n
apt-get install python3-dev python3-pip python3-numpy

CentOS (release 7.2 and later):

yum install epel-release
yum install git clang gcc-c++ make cmake openssl-devel opencv-devel libcurl-devel sox-devel boost-devel boost-filesystem boost-system
For Python 2.7
yum install python-pip python-devel
For Python 3.n
yum install python-pip python34-pip python34-devel python34-opencv python34-numpy


brew tap homebrew/science
brew install opencv
brew install sox
brew install boost

Distributed Aeon

Please take a look at distributed documentation.

Code coverage

Code coverage in aeon depends on llvm-cov and lcov.
Report will be generated in html-coverage-report/index.html


sudo apt-get install llvm lcov
mkdir build
cd build
# COVERAGE flag must be set to generate coverage report
cmake .. -DCOVERAGE=ON
# If you want to generate report when unit test fails: make -i coverage
make coverage

To install Aeon:

git clone
For Python 2.7
cd aeon
pip install -r requirements.txt
mkdir -p build && cd $_ && cmake .. && pip install .
For Python 3.n
cd aeon
pip3 install -r requirements.txt
mkdir -p build && cd $_ && cmake .. && pip3 install .

Note: if installing system wide (as opposed to within a virtual environment) you may need to run sudo

Now continue on to the user guide to get started using aeon. Or to the developer guide to developing custom loaders/transformers.


The complete documentation for aeon is available here.
