FIXED: Pydantic issubclass error for python 3.8 and 3.9 #12659

adrianeboyd · 2023-05-23T08:43:17Z

UPDATE: This is now fixed for spacy v3.4 and v3.5 with the release of Pydantic v1.10.8.

New installs with pip install spacy should work without issue.

To fix an existing venv for spacy v3.4 or v3.5, please upgrade Pydantic to the latest compatible version with:

python -m pip install -U pydantic spacy

Or for a specific version of spacy:

python -m pip install -U pydantic spacy==3.4.4

For spacy v3.2 and v3.3, we have published patch releases with fixes for the typing_extension requirement. Upgrade to spacy v3.2.6+ or v3.3.3+:

python -m pip install 'spacy~=3.2.6'

python -m pip install 'spacy~=3.3.3'

Original report:

There appears to be a bug in Pydantic v1.10.7 and earlier related to the recent release of typing_extensions v4.6.0 that causes errors for import spacy and any other spacy commands for python 3.8 and python 3.9.

We're hoping that there will be an upstream fix soon. You can follow this issue for more details: pydantic/pydantic#5821

As a workaround, you can add typing_extensions<4.6.0 to your requirements.

The error traceback looks like this:

  File "pydantic/main.py", line 197, in pydantic.main.ModelMetaclass.__new__
  File "pydantic/fields.py", line 506, in pydantic.fields.ModelField.infer
  File "pydantic/fields.py", line 436, in pydantic.fields.ModelField.__init__
  File "pydantic/fields.py", line 552, in pydantic.fields.ModelField.prepare

  File "/usr/lib/python3.8/typing.py", line 774, in __subclasscheck__
    return issubclass(cls, self.__origin__)
TypeError: issubclass() arg 1 must be a class

Did the trick typing_extensions<4.6.0

Installing typing_extensions==4.4.0 actually worked, thank you

fastapi 0.99.1 requires typing-extensions>=4.5.0, but you have typing-extensions 4.4.0 which is incompatible.

4.5.0 worked fine

leaving typing extensions at 4.7 and upgrading the pydantic version worked for me!
