New issue 1175: fcoords and tcoords not the same shape for rays from particle datasets https://bitbucket.org/yt_analysis/yt/issues/1175/fcoords-and-tcoords-not-the... Britton Smith: This script: http://paste.yt-project.org/show/6268/ gives the following error: ``` #!python File "test2.py", line 12, in <module> print ray["x"] File "/Users/britton/Documents/work/yt/yt-hg/yt/data_objects/data_containers.py", line 268, in __getitem__ self.get_data(f) File "/Users/britton/Documents/work/yt/yt-hg/yt/data_objects/data_containers.py", line 1181, in get_data self._generate_fields(fields_to_generate) File "/Users/britton/Documents/work/yt/yt-hg/yt/data_objects/data_containers.py", line 1201, in _generate_fields fd = self._generate_field(field) File "/Users/britton/Documents/work/yt/yt-hg/yt/data_objects/data_containers.py", line 305, in _generate_field tr = self._generate_fluid_field(field) File "/Users/britton/Documents/work/yt/yt-hg/yt/data_objects/data_containers.py", line 325, in _generate_fluid_field rv = finfo(gen_obj) File "/Users/britton/Documents/work/yt/yt-hg/yt/fields/derived_field.py", line 184, in __call__ dd = self._function(self, data) File "/Users/britton/Documents/work/yt/yt-hg/yt/geometry/coordinates/coordinate_handler.py", line 40, in _coords rv = data.ds.arr(data.fcoords[...,axi].copy(), units) File "/Users/britton/Documents/work/yt/yt-hg/yt/data_objects/data_containers.py", line 1282, in fcoords return self._current_chunk.fcoords File "/Users/britton/Documents/work/yt/yt-hg/yt/geometry/geometry_handler.py", line 271, in cached_func tr = func(self) File "/Users/britton/Documents/work/yt/yt-hg/yt/geometry/geometry_handler.py", line 322, in fcoords ci[ind:ind+c.shape[0], :] = c ValueError: could not broadcast input array from shape (81,3) into shape (40,3) ``` This seems to be because the fcoords and tcoords for the ray are coming back with different shapes.
