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 ([email protected]) or github.
PyNE has the following dependencies:
Additionally, building the documentation requires the following:
A binary distribution of PyNE is hopefully coming soon. Until then, please install from source.
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 MacOSX, it may be necessary to add the pyne library path to the
DYLD_FALLBACK_LIBRARY_PATH environment variable before running
nuc_data_make. To do this, add the following lines to your
~/.bashrc file where /path/to/pyne/lib is the absolute path to the
directory containing libpyne.dylib
DYLD_FALLBACK_LIBRARY_PATH="${DYLD_FALLBACK_LIBRARY_PATH}:/path/to/pyne/lib"
export DYLD_FALLBACK_LIBRARY_PATH
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 ([email protected]).
