Dear everyone, I recently used yt to plot the slice files for the hdf5 file from PLUTO 4.1. An error exists when ploting, i.e., [('chombo', 'rho'), ('chombo', 'vx1'), ('chombo', 'vx2'), ('chombo', 'vx3'), ('chombo', 'prs')] Traceback (most recent call last): File "simple_slice.py", line 18, in <module> p = yt.ProjectionPlot(ds, "y", "density") File "/home/fangjun/yt/yt-x86_64/src/yt-hg/yt/visualization/plot_window.py", line 1227, in __init__ field_parameters = field_parameters, method = method) File "/home/fangjun/yt/yt-x86_64/src/yt-hg/yt/data_objects/construction_data_containers.py", line 250, in __init__ self.get_data(field) File "/home/fangjun/yt/yt-x86_64/src/yt-hg/yt/data_objects/construction_data_containers.py", line 295, in get_data chunk_fields, "io", local_only = True)): File "/home/fangjun/yt/yt-x86_64/src/yt-hg/yt/utilities/parallel_tools/parallel_analysis_interface.py", line 506, in parallel_objects for obj_id, obj in oiter: File "/home/fangjun/yt/yt-x86_64/src/yt-hg/yt/data_objects/data_containers.py", line 592, in chunks self.get_data(fields) File "/home/fangjun/yt/yt-x86_64/src/yt-hg/yt/data_objects/data_containers.py", line 681, in get_data fluids, self, self._current_chunk) File "/home/fangjun/yt/yt-x86_64/src/yt-hg/yt/geometry/geometry_handler.py", line 252, in _read_fluid_fields chunk_size) File "/home/fangjun/yt/yt-x86_64/src/yt-hg/yt/frontends/chombo/io.py", line 147, in _read_fluid_selection data = self._read_data(g, fname) File "/home/fangjun/yt/yt-x86_64/src/yt-hg/yt/frontends/chombo/io.py", line 104, in _read_data shape = grid.ActiveDimensions + 2*self.ghost AttributeError: 'IOHandlerPlutoHDF5' object has no attribute 'ghost' Could you give some instructions on it?
