Deep learning framework by BAIR
The demo server requires Python with some dependencies.
To make sure you have the dependencies, please run
pip install -r examples/web_demo/requirements.txt, and also make sure that you’ve compiled the Python Caffe interface and that it is on your
PYTHONPATH (see installation instructions).
Make sure that you have obtained the Reference CaffeNet Model and the ImageNet Auxiliary Data:
./scripts/download_model_binary.py models/bvlc_reference_caffenet ./data/ilsvrc12/get_ilsvrc_aux.sh
NOTE: if you run into trouble, try re-downloading the auxiliary files.
python examples/web_demo/app.py will bring up the demo server, accessible at
You can enable debug mode of the web server, or switch to a different port:
% python examples/web_demo/app.py -h Usage: app.py [options] Options: -h, --help show this help message and exit -d, --debug enable debug mode -p PORT, --port=PORT which port to serve content on
In a nutshell: ImageNet predictions are made at the leaf nodes, but the organization of the project allows leaf nodes to be united via more general parent nodes, with ‘entity’ at the very top.
To give “maximally accurate” results, we “back off” from maximally specific predictions to maintain a high accuracy.
bet_file that is loaded in the demo provides the graph structure and names of all relevant ImageNet nodes as well as measures of information gain between them.
