Attribute error for pick_points

[nicolesplaining]

I am trying to get a sounding at a single point for a HRRR forecast. I ran ds.herbie.pick_points(pd.DataFrame({"latitude": [40.76], "longitude": [-111.876183]})) but I'm getting the error AttributeError: 'HerbieAccessor' object has no attribute 'pick_points'. Why is this?

Also, can the same objective (getting a “sounding” at a specific lat/lon point) be accomplished using xoak, since it also uses BallTree?
