Fix for color issue on website

[deirdre-k]

Issue

Scores are showing up in harsher colors than expected. The error comes from a stray np . float added into the opacity for each score chip, which stems from changes to the float type in the most recent version of numpy.

Example

The easy fix is to cast to float. However, this does highlight that the deployed version of the website does not have pinned versions of libraries (unlike current localhost setups) as the docker container uses conda and the environment.yaml instead of requirements.txt. Might be worth considering pinning all version for conda or changing the localhost approach.
