Upon starting jupyter notebook

I am fixing right now

Pull request #337

Replaced collections imports with collections.abc for Sized, Sequence otherwise causes ImportError
Changed in Python 3.3.
Old method stops working in python 3.10

Thanks. I have not tried 3.10 yet so I have not noticed this problem.

I have merged the PR and will check if there is any pending bug that prevents a new release.

@BoPeng Thank you

FYI I removed the following notice

Please Note: collections.abc does not work for OrderedDict still have to use collections I think this need to be raised as a python issue.

Because looking at python documentation I believe this is correct collections.abc has been taken out from collections and contains the Abstract Base Classes for Containers (hence abc) whilst the other classes (specialised container datatypes providing alternatives to Python’s general purpose built-in containers), remain in collections.
