the incompatibility between george.kernels.Matern52Kernel and george.kernels.TaskKernel in robo.fmin.mtbo

Hi @aaronkl

I tried to implement a MTBO program, but I have problems calling robo.fmin.mtbo.

Two kernels are used in robo.fmin.mtbo. i.e., Matern52Kernel and TaskKernel. But neither version of the george version can fit both.

1. I tried the development branch of george, but TaskKernel is undefined.
2. I tried the master branch of george, though TaskKernel is defined, the initialization parameters for Matern52Kernel are apparently different from those defined in robo.fmin.mtbo.

Could you kindly fix this?

Unfortunately, the Taskkernel doesn't work with the latest george version anymore (automl/george development branch) and I don't know how to fix that with their new interface for kernels
