 # 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.
