Counter in Collections module Python

Question

I\'ve come across a really weird problem. I\'m trying to use Counter function in collections module. However, I keep getting the same error message

Attribut         


        

Answer 1

Came across the same issue while installing pandas.

Cause: Counter is only supported in python2.7 and higher and is not available in earlier versions - Counter class got added into collections package in Python 2.7.

Solution 1: As stated by Martin Pieters - use the backport.

Add counter.py at /lib64/python2.6/ - this is where the collections.py is ./lib64/python2.6/collections.py Patch collections.py with:

from counter import Counter

Solution 2: use the backport_collections package. Next patch (the import statement) the package you're getting exception at i.e. pandas in my case:

from backport_collections import Counter

Answer 2

You should use a new version of python AS python 3. You can then use this module. Then import,

import collections
from collections import counter

Answer 3

You're probably using an old version of Python, the Counter class, as stated in the documentation was added in version 2.7.

Answer 4

The Counter class was added to the module in Python 2.7. You are most likely using Python 2.6 or older. From the collections.Counter() documentation:

New in version 2.7.

On python 2.5 or 2.6, use this backport instead.
