Two pytests are failing in our GitHub Action

The two failing pytests in #213 should be fixed. Exception: Solving failed, conditional_maxiter reached

Can you provide a direct link to the logs? I browsed some but couldn't immediately find the errors:

Thanks, my guess is that the underlying solver (I think those tests are using scipy's solvers) may have changed some defaults of the solver settings. It's often tricky to get nonlinear solvers to converge, so I'm not too alarmed about these failures, but we should definitely fix them so that all tests do pass. I'm OK with putting a @xfail decorator on those tests as well.
