PyTorch Wrapper for Point-cloud Earth-Mover-Distance (EMD)
Dependency
The code has been tested on Ubuntu 16.04, PyTorch 1.1.0, CUDA 9.0.
Usage
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.
