This fork: API similar to scipy.optimize
This is a Python wrapper around Naoaki Okazaki (chokkan)'s liblbfgs library of quasi-Newton optimization routines (limited memory BFGS and OWL-QN).
This package aims to provide a cleaner interface to the LBFGS algorithm than is currently available in SciPy, and to provide the OWL-QN algorithm to Python users.
example.py currently only Python2.. Type:
python2 setup.py build_ext --inplace python2 example.py
Type:
pip install pylbfgs
Type:
pip install "pip>=10" pip install -r requirements.txt pip install -e .
To run the test suite:
pytest tests
PyLBFGS was written by Lars Buitinck.
Alexis Mignon submitted a patch for error handling.
