Unable to import Pegasos module (because atleast2d_or_csr is absent)

[ChrisBg]

Hi Ejlb,

I' d like to use your pegasos library but when I try to import pegasos in python I obtain an ImportError which is the following:

Python 2.7.9 |Anaconda 2.2.0 (64-bit)| (default, Mar 9 2015, 16:20:48)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2

import pegasos
Traceback (most recent call last):
File "", line 1, in
File "pegasos/init.py", line 18, in
from .models import SVMPegasosBase, LogisticPegasosBase
File "pegasos/models.py", line 20, in
from .base import PegasosBase
File "pegasos/base.py", line 21, in
from sklearn.utils import atleast2d_or_csr
ImportError: cannot import name atleast2d_or_csr

I'm using the current version of scikit learn (0.16.1) in which atleast2d_or_csr isn't available.

Please would you have an idea or a solution ?

Thank you in advance,

Chris

pip install --user scikit-learn==0.13.1
