IOError: You have attempted to connect to an IPython Cluster but no Controller could be found

Hi. I tried the 'Getting started: 30 seconds to MLBox', but I have this error when read and preprocess the files:

data = Reader(sep=",").train_test_split(paths, target_name)  #reading
data = Drift_thresholder().fit_transform(data)  #deleting non-stable variables

IOError: You have attempted to connect to an IPython Cluster but no Controller could be found.
Please double-check your configuration and ensure that a cluster is running.

Before successfully started a cluster with:

ipcluster start

Also I checked at the same notebook this without error:

import os
import ipyparallel as ipp
rc = ipp.Client()
ar = rc[:].apply_async(os.getpid)
pid_map = ar.get_dict()
pid_map

{0: 10634,
 1: 10639,
 2: 10644,
 3: 10649,
 4: 10654,
 5: 10674,
 6: 10662,
 7: 10688}

Could you help me? I really want to try your MLBox 😄

Thanks.

I tried to copy the directory ~/.ipython/profile_default to ~/.jupyter/profile_default and didn't work.

Hello,

hum did you wait 30 sec after importing mlbox ? Otherwise, It won't work and you will have to stop ipcluster engines :

os.system("ipcluster stop --profile=home &")

and start a again :

os.system("ipcluster start --profile=home &")

I see the same issue on my end too. Here is the stack trace of the error on my end:

Traceback (most recent call last): File "E:/some_folder/mlbox_pipeline.py", line 19, in <module> data=mlb.preprocessing.Reader(sep=",").train_test_split(["data/train_imputed2.csv","data/test_imputed2.csv"],'SalePrice') File "C:\ProgramData\Anaconda3\lib\site-packages\mlbox\preprocessing\reader.py", line 175, in __init__ self.__client = ipp.Client(profile='home') File "C:\ProgramData\Anaconda3\lib\site-packages\ipyparallel\client\client.py", line 399, in __init__ raise IOError(no_file_msg) OSError: You have attempted to connect to an IPython Cluster but no Controller could be found. Please double-check your configuration and ensure that a cluster is running.

P.S. I managed to install MLBox on Windows 7, 64-bit

It has just been fixed, so you can have a try ! It should work now..
