Installs:

With PIP:

pip3 install Neat-EO.pink

With Ubuntu 19.10, from scratch:

# Neat-EO.pink [mandatory]
sudo sh -c "apt update && apt install -y build-essential python3-pip"
pip3 install Neat-EO.pink && export PATH=$PATH:~/.local/bin

# NVIDIA GPU Drivers [mandatory]
wget http://us.download.nvidia.com/XFree86/Linux-x86_64/435.21/NVIDIA-Linux-x86_64-435.21.run
sudo sh NVIDIA-Linux-x86_64-435.21.run -a -q --ui=none

# Extra CLI tools [used in tutorials]
sudo apt install -y gdal-bin osmium-tool

# HTTP Server [for WebUI rendering]
sudo apt install -y apache2 && sudo ln -s ~ /var/www/html/neo

NOTAS:

• Requires: Python 3.6 or 3.7
• GPU with VRAM >= 8Go is mandatory
• To test Neat-EO.pink install, launch in a new terminal: neo info
• If needed, to remove pre-existing Nouveau driver: sudo sh -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf && update-initramfs -u && reboot"

Architecture:

Neat-EO.pink use cherry-picked Open Source libs among Deep Learning, Computer Vision and GIS stacks.

GeoSpatial OpenDataSets:

• Christoph Rieke's Awesome Satellite Imagery Datasets
• Zhang Bin, Earth Observation OpenDataset blog

• The Lovász-Softmax loss: A tractable surrogate for the optimization of the IoU measure in neural networks
• Albumentations: fast and flexible image augmentations

Contributions and Services:

• Pull Requests are welcome ! Feel free to send code... Don't hesitate either to initiate a prior discussion via gitter or ticket on any implementation question. And give also a look at Makefile rules.

• If you want to collaborate through code production and maintenance on a long term basis, please get in touch, co-edition with an ad hoc governance can be considered.

• If you want a new feature, but don't want to implement it, DataPink provide core-dev services.

• Expertise, assistance and training on Neat-EO.pink are also provided by DataPink.

• And if you want to support the whole project, because it means for your own business, funding is also welcome.

Requests for funding:

We've already identified several new features and research papers able to improve again Neat-EO.pink, your funding would make a difference to implement them on a coming release:

• Increase again accuracy :

  • on low resolution imagery
  • even with few labels (aka Weakly Supervised)
  • Topology handling
  • Instance Segmentation

• Improve again performances

• Add support for :

  • Time Series Imagery
  • StreetView Imagery
  • MultiHosts scaling
  • Vectors post-treatments
  • ...
