# Environment Setup


- We use conda to install required packages:
```
    conda env create -f env/env_equiformer_v2.yml
```

- This will create a new environment called `equiformer_v2`.

- We activate the environment:
```
    export PYTHONNOUSERSITE=True    # prevent using packages from base
    conda activate equiformer_v2
```

- After setting up the environment, clone OC20 GitHub repository and install `ocpmodels`:
```
    git clone https://github.com/Open-Catalyst-Project/ocp
    cd ocp
    git checkout 5a7738f
    pip install -e .
```

- The correpsonding version of OC20 GitHub repository is [here](https://github.com/Open-Catalyst-Project/ocp/tree/5a7738f9aa80b1a9a7e0ca15e33938b4d2557edd).
