PyStemmusScope 0.1.1

This repository includes the python package PyStemmusScope for running the STEMMUS-SCOPE model.

The model source code, executable file and utility files are available in the STEMMUS_SCOPE repository.

The input datasets are available on Snellius and CRIB. First, make sure you have right access to the repository and data. Then, see the notebook run_model_in_notebook.ipynb which provides different options to run the model, see Run the model.

Run the model

1. Using executable file: As a user, you don't need to have a MATLAB license to run the STEMMUS-SCOPE model. If PyStemmusScope and MATLAB Runtime are installed on a Unix-like system (e.g. your own machine, Snellius or WSL), you can run STEMMUS_SCOPE using the executable file.
2. Using Matlab: If PyStemmusScope and Matlab are installed, you can run STEMMUS_SCOPE from the source code, for example on Snellius or CRIB.
3. Using Octave: If PyStemmusScope and latest Octave including required packages are installed, you can run STEMMUS_SCOPE from its source code, for example on CRIB or your own machine.

See section Installations for required packages.

Installations

On Snellius

Snellius is the Dutch National supercomputer hosted at SURF. MATLAB and MATLAB Runtime are installed on Snellius, see the script run_jupyter_lab_snellius.sh on how to load the module. Also, use the same script to create a jupyter lab server for running notebooks interactively. The script activates the conda environment pystemmusscope. Make sure that you create the pystemmusscope conda environment before submitting the the bash script. See Create pystemmusscope conda environment.

On CRIB

CRIB is the ITC Geospatial Computing Platform. You can run the model using Matlab or Octave. Currently, running the exceutable file on CRIB is not supported because MATLAB Runtime can not be installed there. See Install PyStemmusScope.

On your own machine

Choose how do you want to run the model, see Run the model.

Install PyStemmusScope

Run the commands below in a terminal (On Windows, use python instead of python3):

python3 -m pip install pystemmusscope

or

Open a jupyter notebook and run the code below in a cell:

!pip install pystemmusscope

Install jupyterlab

Jupyterlab is needed to run notebooks. Run the commands below in a terminal:

python3 -m pip install jupyterlab

Open a terminal, make sure the environment is activated. Then, run jupyter lab:

jupyter lab

JupyterLab will open automatically in your browser. Now, you can run the notebook run_model_in_notebook.ipynb.

Install MATLAB Runtime

To run the STEMMUS_SCOPE, you need MATLAB Runtime version 2021a and a Unix-like system.

In a terminal:

# Download MATLAB Runtime for Linux
wget https://ssd.mathworks.com/supportfiles/downloads/R2021a/Release/6/deployment_files/installer/complete/glnxa64/MATLAB_Runtime_R2021a_Update_6_glnxa64.zip

# Unzip the file
unzip MATLAB_Runtime_R2021a_Update_6_glnxa64.zip -d MATLAB_Runtime

# Install it
cd MATLAB_Runtime
sudo -H ./install -mode silent -agreeToLicense yes

For more information on how to download and install MATLAB Runtime, see the links below:

• installation

Install WSL

As the STEMMUS-SCOPE executable only supports Unix-like systems, Windows users cannot run STEMMUS-SCOPE natively. However, users of Windows 10 and newer can use WSL (Windows Subsystem for Linux) to run the model. Check the Microsoft Guide for a compatibility information and for general WSL instructions. If no installation exists, a Ubuntu distribution can be installed using the following commands:

wsl --install

After installation, you can start up the WSL instance and update the default software:

sudo apt update && sudo apt upgrade

You can now set up a python environment using either python's venv, or use Conda/Mamba. Note that the command to run python and pip can be python3 and pip3 by default.

For the rest of the installation instructions simply follow the steps below. Note that it is possible to access files from the Windows filesystem from within WSL, by accessing, e.g., /mnt/c/ instead of C:\. This means that large input data files can be stored on your Windows installation instead of inside the WSL distro. However, WSL does not have write permission. Therefore, output data will be stored within WSL. Make sure that WorkDir in the model config file is set correctly.

Create pystemmusscope conda environment

If a conda environment is neeed, run the commands below in a terminal:

# Download and install Mamba on linux
wget https://github.com/conda-forge/miniforge/releases/latest/download/Mambaforge-pypy3-Linux-x86_64.sh
bash Mambaforge-pypy3-Linux-x86_64.sh -b -p ~/mamba

# Update base environment
. ~/mamba/bin/activate
mamba update --name base mamba

# Download environment file
wget https://raw.githubusercontent.com/EcoExtreML/STEMMUS_SCOPE_Processing/main/environment.yml

# Create a conda environment called 'pystemmusscope' with all required dependencies
mamba env create -f environment.yml

# The environment can be activated with
. ~/mamba/bin/activate pystemmusscope
