no image displayed with folium and pandas

[Declaix]

Hi,
I am trying to use folium and pandas and I ran the following script under ubuntu 18 with python3 under geany :

#! python3
# coding: utf-8

'''

'''

import os.path, sys
import folium
import pandas

racine = '/mnt/0ea0b27f-3be6-4d2c-b157-a62559e56142/'
fich_csv = 'python3/prog/gpx/csvfile'

franchises = pandas.read_csv(racine+fich_csv)
print("--", franchises)
#view the dataset
franchises.head()

center = [-0.023559, 37.9061928]
map_kenya = folium.Map(location=center, zoom_start=8)
#display map
map_kenya

for index, franchise in franchises.iterrows():
    location = [franchise['latitude'], franchise['longitude']]
    folium.Marker(location, popup = f'Name:{franchise["store"]}\n Revenue($):{franchise["revenue"]}').add_to(map_kenya)

#display the map
map_kenya

My problem : nothing is displayed.

Thanks for your help

My problem : nothing is displayed.

I guess you running it as a plain Python script?
This in meant to be run in notebook environment like Jupyter Notebooks or Google colab(has folium pre-installed).

Doc folium
So to display it without Notebook can save as html.

m.save('index.html')

Then open that html file to get same display as in Notebook.
