Dear Ruth,

I'm playing with the library but I see an error as soon as I try to execute "gprot-fit":

gprot-fit -h Traceback (most recent call last): File "/Users/covino/Pacchetti/anaconda3/bin/gprot-fit", line 4, in import('pkg_resources').run_script('gprot==0.1', 'gprot-fit') File "/Users/covino/Pacchetti/anaconda3/lib/python3.7/site-packages/pkg_resources/init.py", line 666, in run_script self.require(requires)[0].run_script(script_name, ns) File "/Users/covino/Pacchetti/anaconda3/lib/python3.7/site-packages/pkg_resources/init.py", line 1446, in run_script exec(code, namespace, namespace) File "/Users/covino/Pacchetti/anaconda3/lib/python3.7/site-packages/gprot-0.1-py3.7.egg/EGG-INFO/scripts/gprot-fit", line 10, in from gprot.model import GPRotModel, GPRotModel2 File "/Users/covino/Pacchetti/anaconda3/lib/python3.7/site-packages/gprot-0.1-py3.7.egg/gprot/model.py", line 10, in from george.kernels import ExpSine2Kernel, ExpSquaredKernel, WhiteKernel, CosineKernel ImportError: cannot import name 'WhiteKernel' from 'george.kernels' (/Users/covino/Pacchetti/anaconda3/lib/python3.7/site-packages/george/kernels.py)

I think it is just a change in the "george" library, the WhiteKernel.

Thanks, Stefano

Hi Stefano,

Thanks for raising this issue. Unfortunately, I am no longer maintaining this package. If you're interested in using GPs to measure rotation periods, I recommend celerite or exoplanet.
