possible bug in dump method

[lodurality]

Pipeliner doesn't dump config in the old version. Maybe it's because we are trying to pickle lambdas as well

/home/deaddy/Repos/Connectomics/Reskit/reskit/core.py in dump(self, path)
    116         with open(path, 'wb') as f:
    117             for attr in sorted(self.__dict__.keys()):
--> 118                 dump(getattr(self, attr), f)
    119 
    120     def load(self, path):

AttributeError: Can't pickle local object 'gen_dist.<locals>.<lambda>'

[lodurality]

I found the solution -- it's lambda usage indeed

def gen_dist(p): return lambda x,y: minkowski(x.reshape(-1),y.reshape(-1),p)

We should use partial from functools in future:

from functools import partial
def gen_dist(x, y, p): 
    return minkowski(x.reshape(-1),y.reshape(-1),p)

func_list = [chebyshev] + [partial(gen_dist, p=i) for i in [1, 2]]
