The code contained in this repository has been tested on Ubuntu 20.04 with Python 3.8.6.

Setup

Create a virtual environment and install the library pycarus:

$ python3 -m venv .venv
$ source .venv/bin/activate
$ pip install -U pip setuptools
$ pip install pycarus

Then, try to import pycarus to get the command that you can run to install all the needed Pytorch libraries:

$ python3
>>> import pycarus
...
ModuleNotFoundError: PyTorch is not installed. Install it by running: source /XXX/.venv/lib/python3.8/site-packages/pycarus/install_torch.sh

In this example, you can install all the needed Pytorch libraries by running:

$ source /XXX/.venv/lib/python3.8/site-packages/pycarus/install_torch.sh

This script downloads and installs the wheels for torch, torchvision, pytorch3d and torch-geometric. Occasionally, it may fails due to pytorch3d wheel not being available anymore. If that happens, please let us know or try to install pytorch3d manually.
Finally install the other dependencies:

$ pip install hesiod torchmetrics wandb h5py==3.0.0

Experiments

The code for each experiment has been organized in a separate directory, containing also a README file with all the instructions.

Datasets

Please contact Pierluigi Zama Ramirez (pierluigi.zama@unibo.it) if you need access to the datasets used in the experiments, both the ones containing the raw 3D shapes and the ones with the INRs.
