Hi @tiangolo, fastapi tests are currently failing and therefore causing pydantic tests to fail.

See pydantic/pydantic#2584, fastapi is not compatible with the v1.4 of SQLAlchemy which was released earlier in March, I've had to pin to SQLAlchemy==1.3.23

Please could we fix fastapi (the incompatibility looks like it might be trivial) or pin the dependency?

Once master of fastapi is fixed, we'll need to remember to also remove the hack from pydantic.
