The code has been tested on Ubuntu 16.04, PyTorch 1.1.0, CUDA 9.0.
First compile using
python setup.py install
Then, copy the lib file out to the main directory,
cp build/lib.linux-x86_64-3.6/emd_cuda.cpython-36m-x86_64-linux-gnu.so .
Then, you can use it by simply
from emd import earth_mover_distance
d = earth_mover_distance(p1, p2, transpose=False) # p1: B x N1 x 3, p2: B x N2 x 3
Check test_emd_loss.py for example.
The cuda code is originally written by Haoqiang Fan. The PyTorch wrapper is written by Kaichun Mo. Also, Jiayuan Gu provided helps.
