# Windows installation tutorial

Another [issue#16](https://github.com/YuliangXiu/ECON/issues/16) shows the whole process to deploy ECON on *Windows*

## Dependencies and Installation

- Use [Anaconda](https://www.anaconda.com/products/distribution)
- NVIDIA GPU + [CUDA](https://developer.nvidia.com/cuda-downloads)
- [Wget for Windows](https://eternallybored.org/misc/wget/1.21.3/64/wget.exe)
- Create a new folder on your C drive and rename it "wget" and move the downloaded "wget.exe" over there.
- Add the path to your wget folder to your system environment variables at `Environment Variables > System Variables Path > Edit environment variable`

## Getting started

Start by cloning the repo:

```bash
git clone https://github.com/yuliangxiu/ECON.git
cd ECON
```

## Environment

- Windows 10 / 11
- **CUDA=11.3**
- Python = 3.8
- PyTorch >= 1.12.1 (official [Get Started](https://pytorch.org/get-started/locally/))
- Cupy >= 11.3.0 (offcial [Installation](https://docs.cupy.dev/en/stable/install.html#installing-cupy-from-pypi))
- PyTorch3D = 0.7.1 (official [INSTALL.md](https://github.com/facebookresearch/pytorch3d/blob/main/INSTALL.md), recommend [install-from-local-clone](https://github.com/facebookresearch/pytorch3d/blob/main/INSTALL.md#2-install-from-a-local-clone))

```bash
# install required packages
cd ECON
conda env create -f environment-windows.yaml
conda activate econ

# install pytorch and cupy
pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 --extra-index-url https://download.pytorch.org/whl/cu113
pip install -r requirements.txt
pip install cupy-cuda11x
pip install git+https://github.com/facebookresearch/pytorch3d.git@v0.7.1

# install libmesh & libvoxelize
cd lib/common/libmesh
python setup.py build_ext --inplace
cd ../libvoxelize
python setup.py build_ext --inplace
```
