You can install pyaerocom via conda, pip or from source.
The easiest way to install pyaerocom and all requirements using conda. You can install pyaerocom into a pre-existing conda environment via:
conda install -c conda-forge pyaerocom
Or into a new conda environment (recommended) named pya via:
conda create -c conda-forge --name pya pyaerocom
This will install the latest release of pyaerocom including all requirements. Alternatively, you may install via pip or from source as described in the following.
This will install the latest released version of pyaerocom and its depencencies. NOTE this same pacakge as distributed via conda-forge (see prev. point).:
# install pyaerocom on machines with Proj8 or newer # e.g. Ubuntu 22.04 LTS (Jammy Jellyfish) python3 -m pip install pyaerocom
Or into a new virtual environment (recommended) named .venv via:
# create and activate new virtual environment python3 -m venv --prompt pya .venv source .venv/bin/activate # update pip python3 -m pip install -U pip # install pyaerocom on machines with Proj8 or newer # e.g. Ubuntu 22.04 LTS (Jammy Jellyfish) pip install pyaerocom
Install from source into a conda environment
Please make sure to install all requirements (see below) before installing pyaerocom from source. You can do that with the provided file pyaerocom_env.yml.
pip install --no-deps .
The –no-deps option will ensure that only the pyearocom package is installed, preserving the conda environment.
Alternatively, if you plan to apply local changes to the pyaerocom source code, you may install in editable mode (i.e. setuptools “develop mode”) including the test rependencies:
pip install --no-deps -e .
You may also download and extract (or clone) the GitHub repo to install the very latest (not yet released) version of pyaerocom. Note, if you install in develop mode, make sure you do not have pyaerocom installed already in the site packages directory, check e.g. conda list pyaerocom.
Requirements for a conda environment
A list of requirements is provided in file pyaerocom_env.yml.
Normally, conda will install these requirements along with pyaerocom, however, if you install from source or using pip, you need to install the requirements yourself.
With conda you can install all requirements (specified in previous section) into a new environment using the pyaerocom_env.yml file:
conda env create -n pya -f pyaerocom_env.yml
This will create a new conda environment called pya which can be activated using:
conda activate pya
Alternatively, you can include the requirements into an existing environment. First, activate the existing environment, and then install the dependencies using:
conda env update -f=pyaerocom_env.yml
