Problem with projection / YTQuantity values must be numeric
Hi all, Recently I have seen this error more often:
raise RuntimeError("YTQuantity values must be numeric”)
I have been able to solve most of the problems which were related with units (some packages behave differently if I do units*array or array*unit). However, I’m getting an error when I’m trying to project a field, and I don’t know how to solve that Code: . . def _Disk_H(field, data): center = data.get_field_parameter('center') z = data["z"] - center[2] return np.abs(z) yt.add_field("Disk_H", function=_Disk_H, units="pc", take_log=False, validators=[ValidateParameter('center')]) . . . disk_dd = dd.cut_region(["obj['Disk_H'].in_units('pc') < 1.0e3"]) proj = ds.proj('density', 2,data_source=disk_dd,weight_field='density’) Saludos!

Hi José, Can you try, in your cut region, changing the selection string to this? "obj['Disk_H'].in_units('pc').d < 1.0e3" (It'd be better to multiply 1.0e3 times the unit pc, but I don't know if it's imported at that point.) Also, does the `disk` object work in lieu of a cut_region? On Tue, Jun 18, 2019 at 11:23 AM José Mauricio Utreras <jutreras@ug.uchile.cl> wrote:

Code: . .

. . .
disk_dd = dd.cut_region(["obj['Disk_H'].in_units('pc') < 1.0e3"]) proj = ds.proj('density', 2,data_source=disk_dd,weight_field='density’)
Saludos!
