enzo-mrp-music/get_halo_initial_extent.py not working with yt 4.0.1
by C Bernhardt June 2, 2023

June 2, 2023

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

Porting .ply files to Blender with colors?
by Jill P. Naiman Aug. 14, 2022

Aug. 14, 2022

Hi All, I was curious if anyone has had any luck porting .ply files generated with yt into Blender with colors? It seems to port in the surfaces just fine, but they are a uniform color. From what I can gather, Blender imports .ply files with face color instead of vertex so I tried the surf.export_ply routine with "face" instead of "vertex" for sample_type, but no luck ("vertex" doesn't work either). Let me know if I can provide any more useful info. Thanks for any help, -J

ValueError: 'Invalid filename found when building a RAMSESDataset object: %s'
by moonpigeona＠gmail.com Feb. 24, 2022

Feb. 24, 2022

Hello! I'm attempting to load a RAMSES dataset using yt.load and I keep getting this error. I'm using the most recent version and it still isn't working. I've tried ds = RAMSESDataset("/Users/Downloads/ramses-nodisc/info_00056.txt") and ds = RAMSESDataset("output_00056.txt/info_00056.txt") I've also tried changing the directory where the RAMSES dataset is located and still nothing. These are my imports: import yt from yt.config import ytcfg import pyxsim import soxs import h5py import matplotlib.pyplot as plt from astropy.wcs import WCS from astropy.io import fits from matplotlib.colors import LogNorm import pandas as pd import numpy as np from yt.frontends.ramses.api import RAMSESDataset If anyone can help that would be much appreciated!

Clump Finding for Gadget2 format
by 201s408s＠stu.kobe-u.ac.jp Feb. 21, 2022

Feb. 21, 2022

Dear all, For my master's research, I installed yt and I want to load my research data converted to gadget2 format with yt. The function I want to use is the clump function, and I want to create a similar figure by performing the same processing as the Clump Finding below. https://yt-project.org/doc/cookbook/constructing_data_objects.html#cookbook… First of all, I tried to test with the gadget data placed in the data index, but neither the default nor the hdf5 format works. Is it possible to do Clump Finding in Gadget2 format?
