AttributeError: module 'typing_extensions' has no attribute 'OrderedDictTypedDict'

[redeaglekr]

Hi,
I was using astropy wcs while working with my images. I have been using this code for more than one month and this is the first time I am getting this error. I uninstalled astropy and then re installed v5.0. but the error doesn't go away.

from astropy.wcs import WCS
w = WCS(hdu[1].header)

the error is :

Traceback (most recent call last):
  File "/home/XXXXXXs/.local/lib/python3.8/site-packages/astropy/units/_typing.py", line 9, in <module>
    from typing import Annotated
ImportError: cannot import name 'Annotated' from 'typing' (/usr/lib/python3.8/typing.py)

During handling of the above exception, another exception occurred:

@nstarman added that typing module in #10662 , so hopefully he can advise.

Might also be helpful if you let us know what is this WCS by printing out w.

[redeaglekr]

Hi,

I tried to print "w", but nothing is printed out and same error is repeated. I guess it's from the import.

[pllim]

Ah, right, because the error happened in the WCS call. My bad. Please do this:

print(hdu[1].header)

It seems there is an issue with your typing_extensions installation. Which version do you have ? You could try to uninstall and reinstall it.

[redeaglekr]

Solved! Thanks. uninstall version 3.10 and installed 4.0.1

[nstarman]

Maybe I/we should set a minimum version for typing_extensions...

[lpsinger]

This was closed, but I think that the bug remains: there needs to be a minimum version set for typing_extensions.
