Python pacakge to flatten and fold parameter data structures.
# “Parameter origami”: paragami.
Parameter folding and flattening, parameter origami: paragami*!
This is a library (very much still in development) intended to make sensitivity analysis easier for optimization problems. The core functionality consists of tools for “folding” and “flattening” collections of parameters – i.e., for converting data structures of constrained parameters to and from vectors of unconstrained parameters.

## Using the package.
We welcome new users! However, please be aware that the package is still in development. We encourage users to contact the author (github user rgiordan) for advice, bugs, or if you’re using the package for something important.
To install the latest tagged version, install with pip:
python3 -m pip install paragami.
Note that paragami is under rapid development, so you may want to clone the respository and use the master branch instead.
