Hi all,
I've been trying to do some preliminary experimentation with YT's surface object. I have the following snippet of code:
sphere = ds.sphere(center, radius) surf = ds.surface(sphere, ('gas', 'density'), 1e-23) ratio = (surf.volume() / surf.surface_area).in_units('pc')
However when trying to run the code I get the following error:
File "my_analysis.py", line 107, in contours ratio = (surf.volume() / surf.surface_area).in_units('pc') File "/home/brs/stack/yt/yt/data_objects/selection_objects/data_selection_objects.py", line 1394, in volume return self.quantities.total_quantity(("index", "cell_volume")) File "/home/brs/stack/yt/yt/data_objects/derived_quantities.py", line 172, in __call__ rv = super().__call__(fields) File "/home/brs/stack/yt/yt/data_objects/derived_quantities.py", line 55, in __call__ for sto, ds in parallel_objects(chunks, -1, storage=storage): File "/home/brs/stack/yt/yt/utilities/parallel_tools/parallel_analysis_interface.py", line 527, in parallel_objects for result_id, obj in oiter: File "/home/brs/stack/yt/yt/data_objects/selection_objects/data_selection_objects.py", line 94, in chunks for ci, chunk in enumerate(self.index._chunk(self, chunking_style, **kwargs)): File "/home/brs/stack/yt/yt/geometry/geometry_handler.py", line 233, in _chunk self._identify_base_chunk(dobj) File "/home/brs/stack/yt/yt/geometry/grid_geometry_handler.py", line 335, in _identify_base_chunk gi = dobj.selector.select_grids( File "/home/brs/stack/yt/yt/data_objects/selection_objects/data_selection_objects.py", line 73, in selector raise YTDataSelectorNotImplemented(self._type_name) P019 yt : [ERROR ] 2021-09-13 12:14:32,552 YTDataSelectorNotImplemented: Data selector 'surface' not implemented.
I was hoping someone could help with this. My yt version is 4.1.dev0 and my Python version is 3.8.5 Many thanks, Sam Patrick
