[Tkinter] How to make pyinstaller import the ttk theme?

[royer14]

I have a project done and it is in the following:

import tkinter as tk
from tkinter import ttk
import tkinter.messagebox as tmb
from ttkthemes import ThemedStyle

class UI(ttk.Frame):
    def __init__(self, parent=None):
        super(UI,  self).__init__(parent)
        self.parent = parent
        style = ThemedStyle(parent)
        style.set_theme("arc")
        self.parent.geometry("480x520")
        self.init_ui()

    def init_ui(self):
        self.parent.title("New window")
        self.entrada = ttk.Entry(self, text="insert")
        self.entrada.grid(row=2, column=2) 
        boton = ttk.Button(self, text="puls", command=self.ver)
        boton.grid(row=2, column=3)
        self.pack()

    def ver(self):
        try:
            res = int(self.entrada.get())
            print(res)
        except ValueError:
            tmb.showwarning(title = "error", message = " error")

if __name__== '__main__':
    root = tk.Tk() 
    sug = tk.Label(root, text="example missing")
    sug.pack()
    app = UI(parent=root)
    app.mainloop()

When I use pyinstaller to create an exe, it releases the error that the exported exe program can not be executed: below I leave it as I use it, it should be noted that I have used a thema for the program and I doubt that it is imported.
pyinstaller --windowed ui.py -i icono.ico --onefile
