ImportError：没有名为FileDialog的模块 - 在PyInstaller之后

Question

I have written a program that I have tried to turn into an executable using PyInstaller. Pyinstaller appears to have finished without any errors and I end up with an application in /dist/my_program. However, when I try to run that application a console window flashes up for a second with a traceback:

Edit: I have copied the traceback out. There may be a mistake as I had to type it up from a screenshot because it only flashes up.

Traceback (most recent call last):
File "<string>", line 14, in <module>

ImportError: No module named FileDialog

Below are the imports that I have in my code:

import Tkinter
from tkFileDialog import askopenfilename
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.mlab as mlab
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
import subprocess
from PIL import Image, ImageTk
import os

Does anyone know whats causing this/what the fix is? I presume the error is the importation of tkFileDialog?

Edit2: the program runs fine when I run it in my interpreter (Spyder) but when I packaged it using PyInstaller the resulting application gives this error.

Answer 1

According to this question adding import FileDialog solves the problem. Matplotlib seems to need this.
However, I've used Pyinstaller on a script of mine also importing matplotlib and it gives no such error. So I don't know what exacly is the problem here.
