Get Started

Step 0. Clone the Repo

git clone https://github.com/jiawei-ren/ModelNet-C.git
cd ModelNet-C

Step 1. Set Up the Environment

Set up the environment by:

conda create --name modelnetc python=3.7.5
conda activate modelnetc
pip install -r requirements.txt
cd SimpleView/pointnet2_pyt && pip install -e . && cd -
pip install -e modelnetc_utils

Step 2. Prepare Data

Download ModelNet-C by:

cd data
gdown https://drive.google.com/uc?id=1KE6MmXMtfu_mgxg4qLPdEwVD5As8B0rm
unzip modelnet_c.zip && cd ..

Alternatively, you may download ModelNet40-C manually and extract it under data.

Step 3. Download Pretrained Models

Download pretrained models by

gdown https://drive.google.com/uc?id=11RONLZGg0ezxC16n57PiEZouqC5L0b_h
unzip pretrained_models.zip

Alternatively, you may download pretrained models manually and extract it under root directory.
