Installation

Before installing this package via pip, please install the necessary conda dependencies:

$ conda create -n smos python=3.12
$ conda env update -f environment.yml -n smos

Then

$ pip install smos

should work.

Example installation script

The following script will install miniconda and setup the environment on a UNIX like system. Miniconda will be installed into $HOME/miniconda.

wget https://repo.continuum.io/miniconda/Miniconda-latest-Linux-x86_64.sh -O miniconda.sh
bash miniconda.sh -b -p $HOME/miniconda
export PATH="$HOME/miniconda/bin:$PATH"
git clone git@github.com:TUW-GEO/smos.git smos
cd smos
conda env create -f environment.yml
source activate smos

This script adds $HOME/miniconda/bin temporarily to the PATH to do this permanently add export PATH="$HOME/miniconda/bin:$PATH" to your .bashrc or .zshrc

The second to last line in the example activates the smos environment.

After that you should be able to run:

pytest

to run the test suite.

Build Docker image

• Check out the repo at the branch/tag/commit you want bake into the image
• Make sure you have docker installed and run the command (replace the tag latest with something more meaningful, e.g. a version number)

docker build -t smos:latest . 2>&1 | tee docker_build.log

This will execute the commands from the Dockerfile. I.e. install a new environment from the environment.yml file and install the checked out version of the smos package.

To build and publish the image online, we have a GitHub Actions workflow in .github/workflows/docker.yml
