How to include timzonefinder module while creating an exe file via pyinstaller

Question

I'm trying to create an GUI which, on the basis of user's choice gets the lat and long of US states from a CSV file and gets the current time in that state using timezonefinder and datetime module.

I understand that few states have 2 time zones, but getting only 1 time zone is fine for this project. While I'm able to properly use the code and it functions perfectly as a python script, but when I convert it into an executable using pyinstaller, I get a FileNotFound Error.

Here is the code:

import pandas
from tkinter import *
from tkinter import messagebox
from datetime import datetime
from timezonefinder import TimezoneFinder
import pytz

def get_time(state_choosen):
    
    tf =   TimezoneFinder()
    states_data = pandas.read_csv('data/us_states.csv')
    data_list = states_data.to_dict('records')
    
    for data in data_list:
        if state_choosen == data['state']:
            longitude = data['longitude']
            latitude = data['latitude']
            t_zone = tf.timezone_at(lng=longitude, lat=latitude)    
    
            tzone = pytz.timezone(t_zone)
            current_time = datetime.now(tz=tzone).strftime("%I:%M:%S %p")
            
            return current_time 

And here is the error I get:

Traceback (most recent call last):
  File "tkinter\__init__.py", line 1892, in __call__
  File "main.py", line 179, in city_time
    current_time = us_time.get_time(city)
  File "us_time.py", line 10, in get_time
    tf =   TimezoneFinder()
  File "timezonefinder\timezonefinder.py", line 260, in __init__
  File "timezonefinder\timezonefinder.py", line 118, in __init__
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\vaibhav\\AppData\\Local\\Temp\\_MEI71562\\timezonefinder\\poly_zone_ids.bin'

Please suggest how can I fix this error. or if there is a workaround by including another library that is supported by pyinstaller, or maybe creating an executable by something other then pyinstaller?

I'm but a novice right now, so please suggest the best course of action.

Answer 1

Add this parameter to the command line when running pyinstaller:

--collect-data timezonefinder
