Getting all the cookbook recipes working is absolutely a blocker for 3.0.  I think we're all in agreement on that.  Someone should correct me if I'm wrong, but all of the existing recipes can and will be made to work by porting existing functionality to yt-3.0.  This mostly involves adopting the various newisms, units, field names, etc.  We will not release yt-3.0 with broken functionality.  This is doable on a relatively short timescale I think.  However, the new VR machinery will not be ready for a bit longer, so I think it's ok for that to come in 3.1.

As far as halos are concerned, here's the status there:
- halo_analysis completely replaces the HaloProfiler.  The halo_analysis functionality is fully documented (Thanks Hilary!) and the HaloProfiler has been removed from the source and the docs.
- all halo finders have been ported and are now compliant with halo_analysis (Thanks again to Hilary).
- HaloCatalogTimeSeries is a ways off and will need to be pushed to 3.1 or 3.2.  This is functionality that never existed anywhere, so that's fine.
- the other cards on the halo_analysis board are minor enhancements, not blockers
- the halo mass function is almost ready and has an open PR that just needs a few things cleaned up and it's ready.
- the big thing we are missing is a merger tree as neither of the old ones were ported.  The idea is for them to work with the halo_analysis and HaloCatalogTimeSeries, which will probably require work akin to a redesign.  For this reason, this will probably need to wait until 3.1.

I will continue to work on these, but you're right, we need more people working on these little issues or this will continue to be a big blocker and not get done.  I can assign specific bugs to the specialists on those issues, if it is helpful (see below).

For all issues, see this page: https://trello.com/c/NJMfoXdl/22-be-able-to-run-the-cookbook .  Reading the description can give you some clues as to the source of the error, but the best way to diagnose it is simply to go into the doc cookbook directory and try to run the python script:

e.g.
$ cd $YT_DEST/doc/source/cookbook
$ python script.py



* VR - KDTree issues (Sam Skillman? Matt Turk?)
----amrkdtree_downsampling.py
----camera_movement.py -- something going on with statusbar in brick counting!
----opaque_rendering.py -- same as camera_movement.py
----render_with_box_and_grids.py

* Light Rays and Light Cones (Britton Smith, John Zuhone, Devin Silvia)
----make_light_ray.py
----unique_light_cone_projections.py
----light_cone_projection.py
----light_cone_with_halo_mask.py

* Profiles (Matt Turk, Nathan Goldbaum, other?)
----global_phase_plots.py
----profile_with_variance.py
----rad_velocity.py
----radial_profile_styles.py?
----simple_profile.py
----time_series_profiles.py
----save_profiles.py

* Units working with everything in yt (Nathan Goldbaum, Matt Turk, John Zuhone)
----hse_field.py
----simple_off_axis_projection.py

* Miscellany
----aligned_cutting_plane.py -- something is wrong with the derived quantity AngularMomentumVector() in that it doesn't work fully for gas, but seems to work OK for particles.
----free_free_field.py--creating a new derived field (Matt Turk, Nathan Goldbaum)
----simple_slice_with_multiple_fields.py -- vorticity_squared fails as a field.


This is by no means a requirement to work on this, but it would help to take a look at it to see if you can help correct a small bug here and there if your name is listed here (or even if it isn't!)

Ah - I see that now.

Yes, I agree that fixing the cookbook should be a blocker.  FWIW that card is marked as such.  As I said the other day, the blockers are on the yt-3.0 and the documentation board.  We won't do the yt-3.0 release until all the cards marked as blockers are cleared.

This is a big task - any help we can get on this from anyone following along would be much appreciated.  There are a lot of little tasks or tasks that can be completed in a couple hours by anyone that has a little with yt-3.0.

I think all of the cookbook items are blockers to be honest, because the cookbook recipes should be tests that are seen as failing.

I think there remain some issues in the VR working in 3.0, which I identified on the cookbook post on the trello board for yt-3.0.  For example, I know the overlaying grids and overlaying boundaries does not currently work. 

I don't see this on trello.  Can you make a card and mark it as a blocker?
 
 That may be an easy fix, but it's something to keep in mind.  I was going to work on it last week as I was doing the cookbook update, but I figured it was just going to get replaced with the scene interface, so it wasn't worth the time.

I guess I'd still like to have all of the API breakage occur in the big jump from 2.x to 3.0, but if people really want to get 3.0 out the door asap, then perhaps that isn't compatible. Personally, I'm +1 on waiting to have all the halo+VR stuff in 3.0 instead of 3.1, but if everyone else wants a 3.0 out sooner, I will not block it.  I think having a super fancy VR and awesome halo interface is one of the big pulls to getting people who have not yet switched to join 3.0 (from both 2.x as well as non-users) even if it takes a few more months, but I may be the minority here.

Ok - I think the script in the issue description is sufficient.  Let me know if you need something more detailed.
