"Jpp Python package"
Project description
The jppy Python package
This software provides Python access to functionalities in Jpp, like accessing PDF and NPE functions.
It currently depends on a few Jpp headers (no Jpp compilation needed), which are bundled with the package. However, if you want to use another (newer) Jpp version, make sure the $JPP_DIR is pointing to the Jpp directory.
Installation
If you work on the Lyon CC, you can load the jpp/master module which contains the latest release of jppy:
module load jpp/master
Before installing manually, make sure the $JPP_DIR environment variable is pointing to the Jpp directory otherwise it will use some older Jpp headers for compilation. Please note that only the headers of Jpp are needed, it is not necessary to compile the whole Jpp framework! For the sake of completeness, here is how to do it:
git clone --recursive git@git.km3net.de:common/jpp.git export JPP_DIR=$(pwd)/jpp
You also need the pybind11 headers and on some Linux also the python-dev package:
brew install pybind11 # macOS sudo pacman -S pybind11 # Arch based Linux sudo apt-get install pybind11 python3-dev # Debian based Linux (e.g. Ubuntu)
The package can then be installed via pip:
pip install jppy
or directly from the Git repository to get the latest stable from the master branch:
pip install git+https://git.km3net.de/km3py/jppy
or from a local clone:
git clone https://git.km3net.de/km3py/jppy pip install jppy/
Example - Using PDFs
The latest PDF data files can be downloaded from the KM3NeT SFTP Server. In CC Lyon, these files are stored in $JPP_DIR/data.
Here is an example how to play around with muon PDFs using the jppy module in Lyon. Notice that jppy is already installed in the jpp/master module:
