Some of the unit tests use random seeds. As such any objects used by these
tests may have coverage variations due to the code execution paths differing
between runs. What is important here is the diff coverage is 100%, i.e. what
you added is all covered by tests.
The changes look good. Please see the Jira ticket for a suggestion to
improve efficiency of the computation.

> Hi there !
> I would like to improve the BicubicInterpolator (or the
> PiecewiseBicubicInterpolator) with the possibility to evaluate x, y, xy
> derivatives.
> In the deprecated BicubicSplineInterpolator it was already possibile.
> Before I start writing any lines of code I would like to know the rationale
> about removing this functionality.
> Also, do you have any suggestion or guideline ?
> I forked on github, I would like to contibute with a PR.
> Thank you in advance
