InverseGamma prior broken #502

Open 1Reinier opened 7 years ago

1Reinier commented 7 years ago

Calling GPy.priors.InverseGamma(1e-3, 1e-3) gives the following error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

Probably this is because InvGamma inherits from Gamma

I get the same error running old code which ran fine using python 2.7, after switching to python 3.6.1 and now using GPy's latest release. Has the use of this class changed?

Hello! A bump for this issue, which I am also experiencing.
