Dear yt users,

I just updated yt to 4.0.1 and now I get this error message when trying to run enzo-mrp-music.py from John Wise on https://github.com/jwise77/enzo-mrp-music.

Traceback (most recent call last):

File "enzo-mrp-music/enzo-mrp-music.py", line 264, in <module>

params = find_lagrangian_region(params)

File "enzo-mrp-music/enzo-mrp-music.py", line 177, in find_lagrangian_region

get_center_and_extent(params["halo_info"],

File "enzo-mrp-music/get_halo_initial_extent.py", line 147, in get_center_and_extent

halo_indices, halo_com, shifted = get_halo_indices(my_halo, final_dataset,

File "enzo-mrp-music/get_halo_initial_extent.py", line 119, in get_halo_indices

get_halo_sphere_particles(my_halo, dataset, radius_factor=radius_factor)

File "enzo-mrp-music/get_halo_initial_extent.py", line 73, in get_halo_sphere_particles

my_sphere = pf.h.sphere(my_halo_data['center'], radius_factor * r_200)

AttributeError: 'EnzoDataset' object has no attribute 'h'

I am honestly not sure what the attribute 'h' does in this case, so I didn't know what to try to adjust. Any suggestions for getting around this? Or how can I go back to yt 3?

Kind regards,
