cannot import name 'Sequence' from 'collections' #526

I just try to import MinkowskiEngine, but it has a major problem with its package dependency!

import numpy as np
import torch.nn as nn
import MinkowskiEngine as ME

This is the error that I get on torch.version : '1.13.1+cu117' and python 3.10.6

ImportError: cannot import name 'Sequence' from 'collections' (/usr/lib/python3.10/collections/__init__.py)

This issue pertains to Python 3.10 which the collections package got changed. MinkowskiEngine requires some updates regarding to Python upgrades.

As this link, after python 3.10, Sequence has been moved to collections.abc not collections.

You can use MinkowskiEngine on Python 3.10 by editing the following files.

# You should edit the code that import Sequence as following code..
try: 
    from collections import Sequence
except ImportError:
    from collections.abc import Sequence
