This is a python API for binary_c (versions 2.1.7) by David Hendriks, Rob Izzard and collaborators. Based on the initial set up by Jeff andrews.

Project description

Python module for binary_c

Based on a original work by Jeff Andrews (can be found in old_solution/ directory) updated and extended for Python3 by Robert Izzard, David hendriks

Warning : THIS CODE IS EXPERIMENTAL! 09/06/2019


  • Python3
  • binary_c version 2.1+
  • requirements.txt (no?)

Environment variables

Before compilation you should set the following environment variables:

  • required: BINARY_C should point to the root directory of your binary_c installation
  • recommended: LD_LIBRARY_PATH should include $BINARY_C/src and whatever directories are required to run binary_c (e.g. locations of libgsl, libmemoize, librinterpolate, etc.)
  • recommended: LIBRARY_PATH should include whatever directories are required to build binary_c (e.g. locations of libgsl, libmemoize, librinterpolate, etc.)

Build instructions

To build the module, make sure you have built binary_c (with make in the binary_c root directory), its shared library (with make in the binary_c root directory), and set environment variables as described above, then run the following code in t:

make clean

Then to test the Python module:

python3 ./

You will require whatever libraries with which binary_c was compiled, as well as the compiler with which Python was built (usually gcc, which is easily installed on most systems).

If you want to be able to import the binary_c module correctly for child directories (or anywhere for that matter), execute or put the following code in your .bashrc/.zshrc:

export LD_LIBRARY_PATH=<full path to root dir of repo>:$LD_LIBRARY_PATH
export PYTHONPATH=<full path to root dir of repo>:$PYTHONPATH

Usage notes

When running a jupyter notebook and importing binary_c, it might happen that the module binary_c cannot be found. I experienced this when I executed Jupyter Notebook from a virtual environment which didnt use the same python (version/binary/shim) as the one I built this library with. Make sure jupyter does use the same underlying python version/binary/shim. That resolved the issue for me.

Also: I figured that having binaryc output the log like " t=10e4 ..." (i.e. printing the parameter names as well as their values) would be useful because in that way one can easily have python read that out automatically instead of having to manually copy the list of parameter names.

See examples/ dir for some working examples

When you try to import binary_c_python_api and python complains about it not existing, but you are sure that you correctly included the necessary pythonpaths, then you probably need to rebuild the package.
