Python: Trouble running any additional queries on Geopy output?

have encountered the following – Struggling to wrap my head around it.

Have some data that looks like this:

I’ve written the following Python that works out the distance between the 2 sets of coordinates:

from geopy import distance

# Calculate distance between 2 sets of coordinates
# Result is float64

data['Distance'] = data[['Start_Lat', 'Start_Lng', 'End_Lat', 'End_Lng']].apply(lambda x: distance.distance((x[0],x[1]), (x[2],x[3])).km, axis=1)
print(data['Distance'])
# Create quantiles

data["DisBucket"] = pd.qcut(df_nyc.Aftermath, q=[0, 0.3, 0.7, 1.0], labels=['LOW', 'MEDIUM', 'HIGH'])

The first bit works fine and returns the following as a float64:

The second bit however fails and returns the following:

It doesn’t seem to like the output from Geopy for whatever reason. I haven’t been able to work out away around this. Is there potentially a way to copy across the values without the association to Geopy?

Any advice would be greatly appreciated 🙂
