Name already in use

A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

Note: This package is for use with GPFlow 1.

For Bayesian optimization using GPFlow 2 please see Trieste, a joint effort with Secondmind.
