I am using the same package on Linux (Fedora) and receiving the same error. This is occurring when simply running the example test code:

paramgrid = {"kernel": ["rbf"],
"C" : np.logspace(-9, 9, num=25, base=10),
"gamma" : np.logspace(-9, 9, num=25, base=10)}
random.seed(1)

I also have this suddenly
from sklearn-deap.
For some reason I had to roll back to scikit-learn==0.18.2
, I tried upgrading to 0.19.0 now, and the error went away.
from sklearn-deap.
I have the same issue, but upgrading to sklearn 0.19.1 did not solve the issue.
from sklearn-deap.
I solved it by removing these fromt init
#self.best_score_ = None
#self.best_params_ = None
Looks like they are already declared in the base module, and it creates some trouble for some strange reasons... Any ideas?
Seems to be working just fine without declaring None
Edit: It didn't work. It fails in the end with the same error at:
self._best_score = current_best_score_
self._best_params = current_best_params_
Edit2: It did work in the end by just renaming to something else.
from sklearn-deap.
Maybe something changed with the new version of scikit-learn, I'll see if I have some time to fix this bug.
from sklearn-deap.
This shows how to solve this problem: https://stackoverflow.com/q/35950741/4013571
class Test(BaseSearchCV):
best_score_ = None
def __init__(self):
self.best_score_ = None
t = Test()

Hi,
Getting the attribute error, as shown. installed whatever is mentioned in this thread, still the same error.
