Caffe2 aims to provide an easy and straightforward way for you to experiment
|
|
with deep learning and leverage community contributions of new models and
|
|
algorithms. You can bring your creations to scale using the power of GPUs in the
|
|
cloud or to the masses on mobile with Caffe2's cross-platform libraries.
