Hi all,

I installed Prodigy 1.10.6 in a virtual environment with Python 3.8 (Ubuntu 20.04.02 LTE). When running textcat.manual I get this error message (full traceback at the end)  
" from pydantic import validator, BaseModel, Field, Schema  
ImportError: cannot import name 'Schema' from 'pydantic' (/home/ahe/Venvs/Leydenlabs/venv-llabs/lib/python3.8/site-packages/pydantic/ **init**.cpython-38-x86\_64-linux-gnu.so)

When installing Prodigy in the normal environment everything works fine

thanks,

Andreas

Hi!

This probably happens because `pydantic.fields.Schema` was deprecated in version 1.8 of Pydantic. In your virtual environment, you could install `pydantic==1.7` first, then install Prodigy, and hopefully it should work.

This has been fixed in Prodigy v1.10.7 - the related thread is here for background information: [ImportError: cannot import name 'Schema' from 'pydantic'](https://support.prodi.gy/t/importerror-cannot-import-name-schema-from-pydantic/3948)

Let us know if you'd still run into issues though!
