Is there any progress on this issue? torchsparse is not available due to this problem when multi-gpu learning with pytorch-lighting.

setup.py develop and pip install -e give me the same error "error: could not create 'MinkowskiEngineBackend/_C.cpython-38-x86_64-linux-gnu.so': No such file or directory"

You may have already solved the problem, but I will write down the solution. You can use the load_pc_file function of [data_utils.py](https://github.com/hkust-vgd/scanobjectnn/blob/master/data_utils.py) to properly transform the bin file.

I'm using Python 3.6 I don't know why Python 3.4 check failed...
