Getting an error on install with the spacy version

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
en-core-web-sm 3.6.0 requires spacy<3.7.0,>=3.6.0, but you have spacy 3.5.2 which is incompatible.

I'm having a different problem where I need a newer version of spacy (because of a later dependency on pydantic). Anyways, updating spacy to the latest release [3.6.1] would help both of us.
