python - CDIST is choosing wrong value sometimes

I need to get the closest point from a given point in a screen ( X,Y ), from a list. My code is almost right:

from scipy.spatial.distance import cdist

def closest_detection(centroid,objects):
    lista = []
    for item in objects:
        lista.append([item[5],item[6]])        
    if len(objects)>0:        
        return objects[cdist([centroid], lista)[0].argmin()]
    else:
        return [0,0,0,0,0,0,0]

centroid = (195,139)

list=[
  [0,0,0,0,0,190,143,0,0],
  [0,0,0,0,0,293,66,0,0],
  [0,0,0,0,0,305,55,0,0],
  [0,0,0,0,0,246,87,0,0],
  [0,0,0,0,0,264,47,0,0],
  [0,0,0,0,0,318,82,0,0]
  ]


print(closest_detection(centroid,list))

In this example in a raspberry it returned to me the list[1] but when I try to run it in my computer alone it returned me list[0]

Is there a good way (and safer) to return the list item that is closest to my given X,Y point?
