I have pytorch installed.

Hi this code depends on Torch and is written in Lua. Best, Jiajun

And by everything you means pytorch with python 3.x. and lua packages too. Please specify if any other packages required. On Fri, 17 Jan 2020, 3:22 p.m. Ashish Gupta, <ashishgupta2598@gmail.com> wrote:

As I understand it this project doesn't use the pytorch library. It uses the original torch. You can find it here. You need to read the prerequisites in the README.md more carefully. It specifies everything you need.

I'll paste here the prerequisites so you can take a better look at them:

Prerequisites

Torch

We use Torch 7 (http://torch.ch) for our implementation with these additional packages:

matio or fb.mattorch: we use .mat file for saving voxelized shapes.

Visualization

Basic visualization: MATLAB (tested on R2016b)
Advanced visualization: Python 2.7 with package numpy, matplotlib, scipy and vtk (version 5.10.1)

Note: for advanced visualization, the version of vtk has to be 5.10.1, not above. It is available in the package list of common Python distributions like Anaconda
