AttributeError: 'function' object has no attribute 'values' heatmap

Question

I'm trying to plot a heatmap using this code:

import folium
from folium.plugins import HeatMap

max_Count = (dataM['count'].max())
hmap = folium.Map(location=[53.192838, 8.197006], zoom_start=7,)

hm_wide = HeatMap( list(zip(dataM.latitude.values, dataM.longitude.values, dataM.count.values)), 
                   min_opacity=0.2,
                   max_val=max_Count,
                   radius=17, blur=15, 
                   max_zoom=1, 
                 )

hmap.add_child(hm_wide)

the dataframe looks like that:

                     station    count   latitude    longitude   city
Time                    
2021-05-01 00:00:00 02-MI-JAN-N 11.0    52.5139 13.41780    Berlin
2021-05-01 00:00:00 24-MH-ALB   0.0     52.4925 13.55850    Berlin
2021-05-01 00:00:00 23-TK-KAI   1.0     52.4573 13.51870    Berlin

... ... ... ... ... ...

2021-09-09 23:45:00 50801_Amalienstr    0.0 53.1390 8.22225 Oldenburg

but i'm getting this error:

---------------------------------------------------------------------------

      9                    max_val=max_Count,

AttributeError: 'function' object has no attribute 'values'

Any idea about the reason behind it and how can it be solved? Thank you

UPDATE: I've used dataM['latitude'], dataM['longitude'], dataM['count'] and it works :))

import folium
from folium.plugins import HeatMap

max_Count = (dataM['count'].max())
hmap = folium.Map(location=[53.192838, 8.197006], zoom_start=7,)

hm_wide = HeatMap( list(zip(dataM['latitude'], dataM['longitude'], dataM['count'])), 
                   min_opacity=0.2,
                   max_val=max_Count,
                   radius=17, blur=15, 
                   max_zoom=1, 
                 )

hmap.add_child(hm_wide)
