[Bug] typing._ClassVar AttributeError: module 'typing' has no attribute '_ClassVar' #181

Closed mGalarnyk closed 3 years ago

mGalarnyk commented 3 years ago

I was trying to use this example: https://github.com/ray-project/tune-sklearn/blob/master/examples/sgd.py

and I got the following error.

File "/Users/michaelgalarnyk/opt/anaconda3/lib/python3.7/site-packages/dataclasses.py", line 801, in _process_class for name, type in cls_annotations.items()] File "/Users/michaelgalarnyk/opt/anaconda3/lib/python3.7/site-packages/dataclasses.py", line 801, in <listcomp> for name, type in cls_annotations.items()] File "/Users/michaelgalarnyk/opt/anaconda3/lib/python3.7/site-packages/dataclasses.py", line 659, in _get_field if (_is_classvar(a_type, typing) File "/Users/michaelgalarnyk/opt/anaconda3/lib/python3.7/site-packages/dataclasses.py", line 550, in _is_classvar return type(a_type) is typing._ClassVar AttributeError: module 'typing' has no attribute '_ClassVar'

I am using conda version 0.24.1. Any ideas of how I can fix this?

richardliaw commented 3 years ago

hey @mGalarnyk could you uninstall typing (pip uninstall typing)?

Didn't solve the issue. The full error is
