Hey @stevekola!
As per the Spaces documentation 1, we currently don’t support Streamlit 1.0.0. The currently supported versions are: 0.79.0, 0.80.0, 0.81.1, 0.82.0, 0.83.0, 0.84.2, with 0.84.2 being the default one. We’re working on exposing this in a clearer way in Spaces, but even if you specify 1.0.0 it won’t be used.
