Answer 1

[Everything_is_bad]

1. погуглил за тебя, надо обновить typing_extensions
2. python 3.10 все таки уже "старенький", новые проекты лучше делать на 3.12 - 3.13 (новичкам всё таки 3.12)

Спасибо, попробую

[Артур]

все равно та же ошибка

[Everything_is_bad]

Артур, ну так у тебя версия обновилась или нет?

Answer 2

[Aragorn]

You shoud have typing_extensions>=4.6.1 to run pydantic.

pip install --upgrade вам в помощь
