LBFGS2 optimizer missing from python

The LBFGS2 optimizer seems to be missing from the python pip install - from the docs there should be a couple of classes (which are available in simpleITK) - LBFGS2Optimizerv4Enums and LBFGS2Optimizerv4Template. Only LBFGSB and LBFGS are available (not LBFGS2).

Ive tried on 5.2.1, 5.0 and the 5.3 pre-release both RC1 and RC2.

Is this intentional? Sorry if I am being dense here, but I’ve been using it with simpleITK as was hoping to try it out directly from the itk python interface.

LBFGS2 is indeed missing a wrapping specification. Adding it should be simple. Do you want to give it a try?
