raise KeyError(key) Python

Question

I get this error when executing my code do you have an idea how to fix it? here is the image and the code of the first lines of my csv file, the file is too big to display it entirely. the code is complete. i try to display the points on a map with geoplotlib

enter image description here

import geoplotlib
import csv
import pandas as pd

data = pd.read_csv('E:Projet de Memoir sur les tics/humdataAL.csv')
geoplotlib.dot(data)
geoplotlib.show()

It returns the following error:
