Scipy LBFGS with Lightning
🚀 Feature
Nico Pinto (p.c.) says that the vanilla Scipy LBFGS optimizer has produced really good results for him, better so than Pytorch's LBFGS implementation. I am trying to use this wrapper, but similar to this issue I get error
TypeError: step() missing 1 required positional argument: 'closure'

How can I get the closure to work with Scipy's LBFGS implementation?
