Installation Instruction

Start by cloning the repo:

git clone --recursive [email protected]:pengsongyou/openscene.git
cd openscene

First of all, you have to make sure that you have all dependencies in place. The simplest way to do so, is to use anaconda.

You can create an anaconda environment called openscene as below. For linux, you need to install libopenexr-dev before creating the environment.

sudo apt-get install libopenexr-dev # for linux
conda create -n openscene python=3.8
conda activate openscene

Step 1: install PyTorch (we tested on 1.7.1, but the following versions should also work):

pip install torch==1.7.1+cu110 torchvision==0.8.2+cu110 torchaudio==0.7.2 -f https://download.pytorch.org/whl/torch_stable.html

Step 2: install MinkowskiNet:

sudo apt install build-essential python3-dev libopenblas-dev

If you do not have sudo right, try the following:

conda install openblas-devel -c anaconda

And now install MinkowskiNet:

pip install -U git+https://github.com/NVIDIA/MinkowskiEngine -v --no-deps \
                           --install-option="--force_cuda" \
                           --install-option="--blas=openblas"

If it is still giving you error, please refer to their official installation page.

Step 3: install all the remaining dependencies:

pip install -r requirements.txt

Step 4 (optional): if you need to run multi-view feature fusion with OpenSeg (especially for your own dataset), remember to install:

pip install tensorflow
