Error when calling spacy info

[balachander1964]

Hi, I am Bala and am using Spacy version 3.6.1 with Allen AI SCISPACY. Spacy was working really well a month ago but suddenly stopped working properly. 'Spacy info' throws an exception. My version of Python is 3.8 and Windows Version is 10.x. The following is the exception.

Hi, sorry to hear it! What version of Pydantic do you have installed in your environment?

[Rcrossmeister]

I solved this error by xHi, I guess this issue is caused by the incompatible version of spacy and pydantic. I solved this error by matching their version:

pip install spacy==3.7.2
pip install pydantic==2.4.1
