'Problem in making an exe file using Pyinstaller (file made using tkinter and Custom tkinter)

I am trying to make a small application for data entry using tkinter and custom tkinter. The code runs fine in python and I made the exe file of it using pyinstaller --onefile --noconsole try45.py

But on running the exe file it gives error labelled as "Unhandled exception in script". Details of it are attached as below,

I have also attached the image of the error. The first two lines of it say "Failed to execute script 'try45' due to unhandled exception: [Errno 2] No such file or directory: 'C:\Users\Farzan Bashir\AppData\Local\Temp\_MEI127522\customtkinter\assets\themes\blue.json"

and the details in next lines are,

Traceback (most recent call last): File "try45.py", line 2, in File "", line 1027, in _find_and_load File "", line 1006, in _find_and_load_unlocked File "", line 688, in load_unlocked File "PyInstaller\loader\pyimod03_importers.py", line 495, in exec_module File "customtkinter_init.py", line 3, in File "", line 1027, in _find_and_load File "", line 1006, in _find_and_load_unlocked File "", line 688, in _load_unlocked File "PyInstaller\loader\pyimod03_importers.py", line 495, in exec_module File "customtkinter\widgets\customtkinter_input_dialog.py", line 4, in File "", line 1027, in _find_and_load File "", line 1006, in _find_and_load_unlocked File "", line 688, in _load_unlocked File "PyInstaller\loader\pyimod03_importers.py", line 495, in exec_module File "customtkinter\widgets\customtkinter_label.py", line 4, in File "", line 1027, in _find_and_load File "", line 1006, in _find_and_load_unlocked File "", line 688, in _load_unlocked File "PyInstaller\loader\pyimod03_importers.py", line 495, in exec_module File "customtkinter\widgets\customtkinter_tk.py", line 9, in File "", line 1027, in _find_and_load File "", line 1006, in _find_and_load_unlocked File "", line 688, in _load_unlocked File "PyInstaller\loader\pyimod03_importers.py", line 495, in exec_module File "customtkinter\customtkinter_theme_manager.py", line 83, in File "customtkinter\customtkinter_theme_manager.py", line 16, in load_theme FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\Farzan Bashir\AppData\Local\Temp\_MEI44122\customtkinter\assets\themes\blue.json'

This is a pyinstaller problem, read the customtkinter documentation:

There are several issues in partition:

  • The call to swap is passing values from your list, instead of indices.

  • Even when the previous mistake is corrected, it will either move the pivot value to the low+1 index, or it will not move at all.

  • The returned index i, should be the one where the pivot was moved. In a correct implementation that means i is the last index to which a value was moved, which was the value at index high. This is not what is happening, as already with the first swap the pivot value is moved.

  • The swap should be of the current value with the value at i, so that all values up to the one at index i are less or equal to the pivot value.

Here is the corrected partition function:

def partition(array, high, low):
    pivot = array[high]
    i = low - 1
    for x in range(low, high+1):
        if array[x] <= pivot:
            i+=1
            swap(array, x, i)
    return i

These are the issues in the function g:

  • It is supposed to perform the sort in-place, so the + operator for lists should not occur here, as that would create a new list. Moreover, the base case (in else) does not return anything, so the + operator will fail with an error

  • partition(array,high,low) is called twice, which is not only a waste, but the second call will in most cases return a different result, because the pivot can be different. This means the second call of g will potentially not work with an adjacent partition, but will either leave an (unsorted) gap, or work on an overlapping partition.

Here is a correction for the function g:

def g(array, low, high):
    if low < high:
        i = partition(array, high, low)
        g(array, low, i-1)
        g(array, i+1, high)

You should also consider using a better name than g, and change the order of the high/low parameters for partition: that reversed order is a good way to confuse the readers of your code.

Here is Hoare's quicksort algorithm implemented in Python -

def quicksort(A, lo, hi):
  if lo >= 0 and hi >= 0 and lo < hi:
    p = partition(A, lo, hi)
    quicksort(A, lo, p)
    quicksort(A, p + 1, hi)

def partition(A, lo, hi):
  pivot = A[(hi + lo) // 2]
  i = lo
  j = hi
  while True:
    while A[i] < pivot:
      i += 1
    while A[j] > pivot:
      j -= 1
    if i >= j:
      return j
    swap(A, i, j)

def swap(A, i, j):
  A[i], A[j] = A[j], A[i]

You can write g using lambda if you wish, but I would recommend to define an ordinary function instead -

g = lambda a: quicksort(a, 0, len(a) - 1)

Given a sample input, x -

x = [5,0,9,7,4,2,8,3,1,6]
g(x)
print(x)

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

See this related Q&A if you would like to count the number of comparisons and swaps used.
