Plotly express map that runs fine doesn't work as Pyinstaller exe

with urlopen('https://raw.githubusercontent.com/plotly/datasets/master/geojson-counties-fips.json') as response:
    counties = json.load(response)     #pull shapefile of counties from the web


fig = px.choropleth(data, geojson = counties, locations='FIPS',          #the actual mapping part  
                    color='normalized_dollar_per_MHz_pop',    #change_in_demand, or 'normalized_dollar_per_MHz_pop', 'aggregate_demand'
                    title = "Auction rounds " + str(start_round) + ":" + str(number_of_rounds),
                    animation_frame = "round",
                    scope = 'usa',
                    range_color = [0.02, 0.3] #color continuous midpoint = 0 sub, range_color = [0.02, 0.18] or [0,40]
                    ) #px.colors.diverging.PiYG

   
fig.layout.update(
   updatemenus = [
      go.layout.Updatemenu(
         type = "buttons", direction = "right", active = 0, x = 0., y = 0,
         buttons=[dict(label="Play", method="animate", args=[None]),]
      )
   ]
)

fig.show()

My data frame is called data, with columns including aggregate_demand and a few other variables. I'm creating a slider map in plotly express, and I want to make it so that anyone can run the script. It works just fine, but when I package it as an executable in pyinstaller using '''pyinstaller script.py --onefile''' and run it I get '''

range_color = [0.02, 0.3] #color continuous midpoint = 0 sub, range_color = [0.02, 0.18] or [0,40]

I had the exact same problem, but with px.timeline .

What solved the issue was adding plotly to datas in the PyInstaller spec file. More about this here: https://stackoverflow.com/a/61119844/6286652
