I get an error when running the last part of gwa_tutorial.ipynb "Now, the easy way to do all of this" during the sampler_setup step that model_utils doesn't have setup_sampler.

# Setup a sampler instance.
# This will add some fanicer stuff than before, like prior draws, 
# and custom sample groupings.
sampler = model_utils.setup_sampler(pta, outdir=outdir, resume=False)

If I replace model_utils with sampler and import sampler from enterprise_extensions earlier, then it works. I found this by grepping in enterprise_exentions, so I don't know if this is the Right Thing To Do. There is also a sampler_setup in hypermodel.

The following cell in gwa_tutorial_part2.ipynb gives an error that dm_gp isn't defined:

# full model
if bayesephem:
    s = ef + eq + rn + dm_gp + tm + eph + gw
else:
    s = ef + eq + rn + dm_gp + tm + gw

log10_A_dm and gamma_dm are both defined, so presumably, there should have been something above to the effect of:

dm = utils.powerlaw(log10_A=log10_A_dm, gamma=gamma_dm)
dm_gp = gp_signals.FourierBasisGP(spectrum=dm, components=30, Tspan=Tspan, name='dm')

or else not include dm_gp in the s = ... line.

Also, @stevertaylor, would it be more efficient to create a dwg-tutorials channel on slack for this kind of thing?
