Can Not Import the EvolutionaryAlgorithmSearchCV Call

[BernardOng]

Using the exact code sample, when I ran the code, I get an import error.

Traceback (most recent call last): File "test.py", line 18, in from evolutionary_search import EvolutionaryAlgorithmSearchCV File "D:\Anaconda2\lib\site-packages\evolutionary_search__init__.py", line 1, in from .cv import * File "D:\Anaconda2\lib\site-packages\evolutionary_search\cv.py", line 6, in from deap import base, creator, tools, algorithms File "D:\Python\zillow\deap.py", line 25, in from evolutionary_search import EvolutionaryAlgorithmSearchCV ImportError: cannot import name EvolutionaryAlgorithmSearchCV

`import sklearn.datasets
import numpy as np
import random

data = sklearn.datasets.load_digits()
X = data["data"]
y = data["target"]

from sklearn.svm import SVC

paramgrid = {"kernel": ["rbf"],

Hi! Many people have reported having problems with this library in an Anaconda environment. How did you install sklearn-deap?

[BernardOng]

I installed per instruction as follows (I used Windows 10 and Anaconda, 2x on main, 3x on env): pip install sklearn-deap

I just also tried installing from a cloned source under git and it still created the same issue. I tried under Python v2.7.13 and Python v3.6.2 - same results. Is there a way around this?

Maybe you can use a virtualenv environment instead of using anaconda?
