AttributeError: type object 'Callable' has no attribute '_abc_registry'

Question

When I open my jupyter notebook I get errors.

I use google for help, but I can\'t find an answer.

I\'m on macOS mojave and using python 3.7.2.I reinstalled

Answer 1

Try uninstalling typing:

pip uninstall typing

or downgrading python to 3.6. There seems to be a problem with typing in 3.7

If after that you get:

AttributeError: module 'typing' has no attribute '_ClassVar'

try pip uninstall dataclasses.
