The PyNE project aims to provide a common set of tools for nuclear science and engineering needs.
If you are interested in the package itself, or would like to help and contribute, please let us know either on the mailing list (https://groups.google.com/forum/#!forum/pyne-dev, pyne-dev@googlegroups.com) or github.
Examples, documentation, and more can be found at http://pyne.io/, the official PyNE projectsite.
PyNE has the following dependencies:
Additionally, building the documentation requires the following:
A binary distribution of PyNE is currently available for windows only on 32-bit python using conda. In order to install use the following command:
conda install -c https://conda.binstar.org/batesca pyne_win32py27
Conda binaries are coming soon for other platforms.
Installing PyNE from source is a two-step process. First, download and unzip the source (zip, tar). Then run the following commands from the unzipped directory:
cd pyne/ python setup.py install --user scripts/nuc_data_make
The setup.py command compiles and installs the PyNE source code.
The nuc_data_make builds and installs a database of nuclear data.
Unfortunately, this must be done as a second step because most nuclear
data is under some form of license restriction or export control which
prevents the developers from distributing it with PyNE. However, the
nuc_data_make program (which is installed by setup.py) will
do its best to find relevant nuclear data elsewhere on your machine
or from public sources on the internet.
On mac and linux PyNE can be installed via the package manager conda. After installing anaconda or miniconda from the Continuum downloads page add conda's binary directory to your bash profile by adding:
export PATH=/path/to/anaconda/bin:$PATH
to your .bashrc or .bash_profile. Then in a new shell:
conda install conda-build jinja2 nose setuptools pytables hdf5 scipy
on linux you may also need to run:
conda install patchelf
Then dowload the latest conda-recipes here
cd to the conda-recipes directory and run:
conda build pyne conda install $(conda build --output pyne) nuc_data_make
These instructions are based on using the homebrew http://brew.sh/ package manager Install command line tools from https://developer.apple.com/downloads/ you will need to create an account in order to download:
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go/install)" brew doctor brew tap homebrew/science brew install hdf5 brew install cmake brew install python
Add:
export PATH=/usr/local/bin:$PATH export PATH=/usr/local/share/python:$PATH
to ~/.bash_profile, then:
source ~/.bash_profile sudo pip install numpy sudo chown -R $(whoami) /usr/local brew install gfortran pip install scipy pip install cython pip install numexpr pip install tables
download pyne-staging cd to that directory:
cd Downloads/pyne-staging python setup.py install
Once those lines have been added, run the following command before running
nuc_data_make:
source ~/.bashrc
We highly encourage contributions to PyNE! If you would like to contribute, it is as easy as forking the repository on GitHub, making your changes, and issuing a pull request. If you have any questions about this process don't hesitate to ask the mailing list (https://groups.google.com/forum/#!forum/pyne-dev, pyne-dev@googlegroups.com).
