enzo-mrp-music/get_halo_initial_extent.py not working with yt 4.0.1

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, -- Carla Bernhardt PhD Student Universität Heidelberg ZAH Institut für Theoretische Astrophysik

Hey guys, just wanted to ask if someone got experience in loading results from Fluent with yt. I only got errors when trying to load the dat.h5 files saying missing "keys" while loading database.

NAN occurs when calculating second-order gradient fields
by hyf＠stu.pku.edu.cn May 10, 2023

May 10, 2023

Hi everyone， I have tried to use the function 'add_gradient_fields' to calculate the second-order derivative of density 'rho' with x-direction, i.e., 'rho_gradient_x_gradient_x'. Here is the code: rho_gradientx = ds.add_gradient_fields(('boxlib','rho')) ds.periodicity = (True, True, True) rho_gradientxx = ds.add_gradient_fields(('boxlib','rho_gradient_x')) Unfortunately, nan occurs when I tried to plot the field 'rho_gradient_x_gradient_x' I will be appreciate if anyone can give me suggestions about how to fix it or provide other solutions to calculate higher order(more than 1st order) gradient fields. Best wishes, He Yifeng

Splitting ewah_bool_utils
by Matthew Turk May 8, 2023

May 8, 2023

Hi folks, Just a heads up that we're going to merge https://github.com/yt-project/yt/pull/2711 soon. This takes some code that was yt specific and moves it to an external package (where perhaps it can find use outside of yt). The only impact this will have is if you are accustomed to installing yt from source, where you will now need to also have this installed. If you are used to using yt from conda, pip, etc, then the dependency resolution will pick up the change and install it. *But*, if you are installing yt from source, you'll also need to install 'ewah_bool_utils' which is located at: https://github.com/yt-project/ewah_bool_utils , as well as on conda-forge, pypi, etc. -Matt
