Pynistaller .exe does not seem to embeded Python

Question

I created an .exe file with pyinstaller on Windows but when I try to open it on another Windows computer I have a traceback.

To create the .exe, I installed Python 3.7.

Then I pip installed pyinstaller and run it with --onefile:

PS> py -3.7 -m pip install pyinstaller 
PS> pyinstaller --onefile hello_world.py 

I expect that pyinstaller --onefile

• embeded in the exe file everything including the Python.
• On the traceback I see that the python interpreter is the c:\users\helen\appdata\local\programs\python\python37 this is the Python I used to create the .exe. This Python is not suppose to exist in the target Windowe I execute the .exe

My goal is to make this .exe work on any computer.

Am I missing something ? Are there other arguments for pyinstaller to prevent those kinds of errors ?

important note: this is not a question relate to including pandas in pyinstaller PyInstaller and Pandas

hello_world.py

My hello_world.py is just a simple script using Tkinter to print hello world.

import tkinter as tk
import pandas as pd

class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.master.geometry("250x50")
        self.master.title("POC")
        self.pack()
        self.create_widgets()

    def create_widgets(self):
        self.hi_there = tk.Label(self)
        self.hi_there["text"] = "Hello World"
        self.hi_there.pack(fill='x', side="top")
        self.quit = tk.Button(self, text="QUIT", fg="red",
                              command=self.master.destroy)
        self.quit.pack(side="bottom")


root = tk.Tk()
app = Application(master=root)
app.mainloop()

traceback
