Description

ez_map2 fails for solvers. Throws traceback ending which includes: 

  File "./tmp-XBI61.py", line 3, in function_wrapper
    return function(_x) + penalty_function(_x)
NameError: global name 'function' is not defined

ez_map2 is equivalent to Mpi( nodes, source=True ).map... which exhibits similar defect

comment:2 Changed 3 years ago by mmckerns

point of failure seems to stem from mystic.tools.wrap_penalty: 

def wrap_penalty(function, penalty_function):
    """append a function call to a function object

This is useful for binding a penalty function to a cost function;
thus, the penalty will be evaluated at every cost function evaluation.
    """
    def function_wrapper(x):
        _x = x[:] #XXX: trouble if x not a list or ndarray... maybe "deepcopy"?
        return function(_x) + penalty_function(_x)
    return function_wrapper

Here is the traceback from Mpi(nodes, source=True).map: 

>>> from mystic.solvers import *
>>> def squared(x):
...   return sum(xi**2 for xi in x)
... 
>>> from pyina.launchers import Mpi
>>> p = Mpi(8, source=True).map
>>> 
>>> solver = DifferentialEvolutionSolver2(3)
>>> solver.SetMapper(p)
>>> solver.Solve(squared)

  • Milestone changed from mystic-0.2a2 to mystic-0.3a

This is now a "somewhat deprecated" parallel map in pyina, and the above example does work for source=False, which is the default. This should be included as part of a test suite for solver interactions with pathos/pyina (see #210).

Note: See TracTickets for help on using tickets.
