I am attempting to export a simple GUI that used NLTK as an exe with Python 3.6 and Windows 10.
When I run PyInstaller to freeze my simple program as an exe I get the error: Unable to find "c:\users\usr\nltk_data" when adding binary and data files.
When I even copied the nltk_data folder here and I get an error in a different nltk.data.path path "c:\users\usr\appdata\local\programs\python\python36\nltk_data"
import tkinter as tk
from nltk.corpus import stopwords
sw = stopwords.words('english')
counter = 0
def counter_label(label):
counter = 0
def count():
global counter
counter += 1
label.config(text=sw[counter])
label.after(1000, count)
count()
root = tk.Tk()
root.title("Counting Seconds")
label = tk.Label(root, fg="dark green")
label.pack()
counter_label(label)
button = tk.Button(root, text='Stop', width=25, command=root.destroy)
button.pack()
root.mainloop()
for pyinstaller I run
pyinstaller --onefile -- windowed test_tkinter.py
It seems that it is a known bug to the hook of PyInstaller named nltk. An easy way to fix it is to edit this file:
<PythonPath>/Lib/site-packages/PyInstaller/hooks/hook-nltk.py
And comment the lines iterating over nltk_data:

Remember to replace path_to_nltk_data with your currrent path for nltk_data.
