I am trying to use ML Ensemble. You can see installation details here: http://ml-ensemble.com/info/start/install.html.

I would run in terminal:

pip3 install sklearn
pip3 install mlens
pip3 install pandas
pip3 install -U mlens

and I have Python 3.11.3 installed as well as the newest version of pip. I would then run the attached python file, which would fail at the line from mlens.ensemble import SuperLearner.

The error I get is:

[MLENS] backend: threading
Traceback (most recent call last):

ImportError: cannot import name 'Sequence' from 'collections' (/opt/homebrew/Cellar/python@3.11/3.11.3/Frameworks/Python.framework/Versions/3.11/lib/python3.11/collections/__init__.py)

When I open the init.py file, there seems to be some errors with how it is working. For example, there is this line:

import _collections_abc
import sys as _sys

from itertools import chain as _chain
from itertools import repeat as _repeat
from itertools import starmap as _starmap
from keyword import iskeyword as _iskeyword
from operator import eq as _eq
from operator import itemgetter as _itemgetter
from reprlib import recursive_repr as _recursive_repr
from _weakref import proxy as _proxy

try:
    from _collections import deque
except ImportError:
    pass
else:
    _collections_abc.MutableSequence.register(deque)

try:
    from _collections import defaultdict
except ImportError:
    pass

and it underlines _collections (i.e. it is not recognizing it). Is this an error with Python3 or with ML Ensemble?

I have messed around a bit with the init.py file, but that does not seem to be solving it. Is this an error with ML Ensemble or Python? Should I try uninstalling and reinstalling python3? How can I go about resolving this import error?
