Code that works in pandas should work for chainladder

import chainladder as cl
clrd = cl.load_sample('clrd')
clrd_pd = clrd.sum('origin').sum('development').to_frame()

groups = [i.find('Loss')>=0 for i in clrd.columns]

# Works for pandas
clrd_pd.groupby(groups, axis=1).sum(1)
# Fails for chainladder
clrd.groupby(groups, axis=1).sum(1)
