# Setup virtual python environment
Optionally, you can use a [virtual python](https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/) environment to keep dependencies separate. The _venv_ module is the preferred way to create and manage virtual environments. 

 ```console
python3 -m venv env
```

Before you can start installing or using packages in your virtual environment you’ll need to activate it.

```console
source env/bin/activate
pip install --upgrade pip
pip install -r requirements.txt
 ```

### Installing packages

Now that you’re in your virtual environment you can install packages.

```console
python -m pip install --requirement requirements.txt
```

### JupyterLab
Once installed, launch JupyterLab with:

```console
jupyter-lab
```

### Cleanup of virtual environment
If you want to switch projects or otherwise leave your virtual environment, simply run:

```console
deactivate
```

If you want to re-enter the virtual environment just follow the same instructions above about activating a virtual environment. There’s no need to re-create the virtual environment.
