PyTorch Point-cloud Earth-Mover-Distance (EMD) Implementation

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.
