Windows Subsystem for Linux (WSL)

We recommend the use of Windows Subsystem for Linux (WSL) to install PyBaMM, see the instructions below to get PyBaMM working using Windows, WSL and VSCode.

Install WSL

Follow the instructions from Microsoft here. When given the option, choose the Ubuntu 18.04 LTS distribution to install. Don’t forget to initialise the Ubuntu installation using the instructions given here.

Install PyBaMM

Open a terminal window in your installed Ubuntu distribution by selecting “Ubuntu” from the start menu. This should give you a bash prompt in your home directory.

To download the PyBaMM source code, you first need to install git, which you can do by typing

sudo apt install git-core

For easier integration with WSL, we recommend that you install PyBaMM in your Windows Documents folder, for example by first navigating to

$ cd /mnt/c/Users/USER_NAME/Documents

where USER_NAME is your username. Exact path to Windows documents may vary. Now use git to clone the PyBaMM repository:

git clone https://github.com/pybamm-team/PyBaMM.git

This will create a new directly called PyBaMM, you can move to this directory in bash using the cd command:

cd PyBaMM

If you are unfamiliar with the linux command line, you might find it useful to work through this tutorial provided by Ubuntu.

Now head over and follow the installation instructions for PyBaMM for linux here.

Use Visual Studio Code to run PyBaMM

You will probably want to use a native Windows IDE such as Visual Studio Code or the full Microsoft Visual Studio IDE. Both of these packages can connect to WSL so that you can write python code in a native windows environment, while at the same time using WSL to run the code using your installed Ubuntu distribution. The following instructions assume that you are using Visual Studio Code.

First, setup VSCode to run within the PyBaMM directory that you created above, using the instructions provided here.

Once you have opened the PyBaMM folder in vscode, use the Extensions panel to install the Python extension from Microsoft. Note that extensions are either installed on the Windows (Local) or on in WSL (WSL:Ubuntu), so even if you have used VSCode previously with the Python extension, you probably haven’t installed it in WSL. Make sure to reload after installing the Python extension so that it is available.

If you have installed PyBaMM into the virtual environment env as in the PyBaMM linux install guide, then VSCode should automatically start using this environment and you should see something similar to “Python 3.6.8 64-bit (‘env’: venv)” in the bottom bar.

To test that vscode can run a PyBaMM script, navigate to the examples/scripts folder and right click on the create-model.py script. Select “Run current file in Python Interactive Window”. This should run the script, which sets up and solves a model of SEI thickness using PyBaMM. You should see a plot of SEI thickness versus time pop up in the interactive window.

The Python Interactive Window in VSCode can be used to view plots, but is restricted in functionality and cannot, for example, launch separate windows to show plot. To setup an xserver on windows and use this to launch windows for plotting, follow these instructions:

  1. Install VcXsrv from here.
  2. Set the display port in the WSL command-line: echo "export DISPLAY=localhost:0.0" >>  ~/.bashrc
  3. Install python3-tk in WSL: sudo apt-get install python3-tk
  4. Set the matplotlib backend to TKAgg in WSL: echo "backend : TKAgg" >>  ~/.config/matplotlib/matplotlibrc
  5. Before running the code, just launch XLaunch (with the default settings) from within Windows. Then the code works as usual.
