error in module 'attr' when trying to run jupyter notebook

I am trying to run jupyter notebook in windows 10 PC.
After installing miniconda and installed required library, I ran jupyter notebook and got following error.
I have been using jupyter notebook for few years and this is first time to see this error.
Does anyone came across this or know how to solve?

I believe the error will be solved if you install attrs which actually contains both the above mentioned packages.

$ pip uninstall attr
$ pip install attrs

But for that first you would need to uninstall your attr and then install attrs. It should work as expected after the above changes.

pip3 install --upgrade setuptools --user solved the problem for me.

Hope this helps.

I got the same problem and solved it by downgrading the attrs module to 19.2.0
