My role at work includes automating several processes which are easily automated via Python, for use by the entire team at the office. None of my coworkers have Python set up on their devices (we're all Windows) nor would they be comfortable using it if they did, so I've been compiling my work into .exe files with tkinter.
My most recent (and, of course, the most important) program compiles into a onefile .exe without issue, and runs perfectly on my computer. My coworkers are able to open it and load files into it, but when they go to activate some of the tkinter buttons within, one coworker has absolutely nothing happen while another gets a windows error message that the program has crashed. I'm unable to recreate these issues on my side.
The .exe was made using pyinstaller in a virtual environment, in which I installed all necessary dependencies. The script does not need to read or reference any other files in order to run. Is it possible that the .exe is still somehow missing a dependency that it's finding on my device and not others? How can I be sure? Would setting it up to include an installer wizard make a difference? Thanks for the help on this!
I can't include the full script due to character limit, but I've included the opening lines with all imports.

I am very new to using PyQt4. So far, i have used QtDesigner to create the GUI windows i shall be using for my program.
However, when i run the first bit of python coding to get the user interface to appear, i get an error i cannot find a solution to.
Here's the code:
import sys, os
from PyQt4 import QtCore, QtGui, uic
form_class = uic.loadUiType("HomeScreen.ui") [0]
All i am trying to do with this is to load a GUI, which is called 'HomeScreen.ui'.
Upon running this code, the python shell returns an error saying:
from PyQt4 import QtCore, QtGui, uic
ImportError: No module named 'PyQt4'
I have Python 3.5 installed, as well as PyQt v4.11.4 and PyQt5.6.
'QtGui' and 'QtCore' are both saved in a folder called PyQt4 (and PyQt5), which are both stored in the path:
C:\Program Files (x86)\Python\Python35-32\Lib\site-packages
I believe this is where third party modules are supposed to be stored, but python can never find the module and i repeatedly get the same error message.
Any help would be appreciated.
I also work in windows and python 3,just run the execute file to install pyqt:
https://sourceforge.net/projects/pyqt/files/PyQt5/PyQt-5.6/
it works well in my environment
I try to compile a Python project under Windows 7 using PyInstaller. The project works fine, there are no issues, however when I try to compile it the result doesn't work. Though I get no warnings during compilation there are many in the warnmain.txt file in the build directory: warnmain.txt
I don't really understand those warnings, for example "no module named numpy.pi" since numpy.pi is no module but a number. I never tried to import numpy.pi. I did import numpy and matplotlib explicitly. In addition I'm using PyQt4. I thought the error might be related to those libraries.
However I was able to compile a simple script which uses numpy succesfully:
import sys
from PyQt4 import QtGui, QtCore
import numpy as np
class MainWindow(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.pb = QtGui.QPushButton(str(np.pi), self)
app = QtGui.QApplication(sys.argv)
main = MainWindow()
main.show()
sys.exit(app.exec_())
Successfully here means that the created executable file actually showed the desired output. However there is also a warnmain.txt file created which contains exactly the same 'warnings' as the one before. So I guess the fact that compiling my actual project does not give any success is not (or at least not only) related to those warnings. But what else could be the error then? The only output during compilation are 'INFO's and none of the is a negative statement.
I did not specify an additional hook directory but the hooks where down using the default directory as far as I could read from the compile output, e.g. hook-matplotlib was executed. I could not see any hook for numpy neither could I for my small example script but this one worked. I used the following imports in my files (not all in the same but in different ones):
import numpy as np
import matplotlib.pyplot as ppl
from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QTAgg as NavigationToolbar
from PyQt4 import QtGui, QtCore
import json
import sys
import numpy # added this one later
import matplotlib # added this one later
Since PyInstaller does not give any errors/warnings I could not figure out if the problem is related to the libraries or if there is something else to be considered.
Had a similar problem with no module named FileDialog. Discovered that with version 3.2, I could use
pyinstaller --hidden-import FileDialog ...
instead of modifying my main script.
See Listing Hidden Imports documentation
Pyinstaller won't see second level imports. So if you import module A, pyinstaller sees this. But any additional module that is imported in A will not be seen.
There is no need to change anything in your python scripts. You can directly add the missing imports to the spec file.
Just change the following line:
hiddenimports=[],
to
hiddenimports=["Tkinter", "FileDialog"],
If you are getting ModuleNotFoundError: No module named ... errors and you:
call PyInstaller from a directory other than your main script's directory
use relative imports in your script
then your executable can have trouble finding the relative imports.
This can be fixed by:
calling PyInstaller from the same directory as your main script
OR removing any __init__.py files (empty __init__.py files are not required in Python 3.3+)
OR using PyInstaller's paths flag to specify a path to search for imports. E.g. if you are calling PyInstaller from a parent folder to your main script, and your script lives in subfolder, then call PyInstaller as such:
pyinstaller --paths=subfolder subfolder/script.py.
The problem were some runtime dependencies of matplotlib. So the compiling was fine while running the program threw some errors. Because the terminal closed itself immediately I didn't realize that. After redirecting stdout and stderr to a file I could see that I missed the libraries Tkinter and FileDialog. Adding two imports at the top of the main solved this problem.
I was facing the same problem and the following solution worked for me:
I first removed the virtual environment in which I was working.
Reinstalled all the modules using pip (note: this time I did not create any virtual environment).
Then I called the pyinstaller.
The .exe file created thereafter executed smoothly, without any module import error.
I had the same problem with pyinstaller 3.0 and weblib. Importing it in the main didn't help.
Upgrading to 3.1 and deleting all build files helped.
pip install --upgrade pyinstaller
If the matter is that you don't need Tkinter and friends because you are using PyQt4, then it might be best to avoid loading Tkinter etc altogether. Look into /etc/matplotlibrc and change the defaults to PyQt4, see the 'modified' lines below:
#### CONFIGURATION BEGINS HERE
# The default backend; one of GTK GTKAgg GTKCairo GTK3Agg GTK3Cairo
# CocoaAgg MacOSX Qt4Agg Qt5Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG
# Template.
# You can also deploy your own backend outside of matplotlib by
# referring to the module name (which must be in the PYTHONPATH) as
# 'module://my_backend'.
#modified
#backend : TkAgg
backend : Qt4Agg
# If you are using the Qt4Agg backend, you can choose here
# to use the PyQt4 bindings or the newer PySide bindings to
# the underlying Qt4 toolkit.
#modified
#backend.qt4 : PyQt4 # PyQt4 | PySide
backend.qt4 : PyQt4 # PyQt4 | PySide
May not be a good practice but installing pyinstaller in the original environment used in my project (instead of a separate venv) helped resolve ModuleNotFoundError
I had similar problem with PySimpleGUI.
The problem was, pyinstaller was installed in different directory.
SOLUTION (solved for me) : just install pyinstaller in the same directory in which the file is present (that to be converted to exe)
If these solutions don't work, simply deleting and reinstalling pyinstaller can fix this for you (as it did for me just now).
Putting this here for anyone else who might come across this post.
I had the same error. Mine said "ModuleNotFoundError: No module named 'numpy'". I fixed it by typing the following in the cmd:
pip install pyinstaller numpy
I know this is a long shot but I'm hoping someone on here has any experience with this as I can't find anything mentioning it online. I have a python script that imports modules from Autodesk Maya. This python script is run through mayapy.exe instead of python.exe which is whats throwing me off. I would rather not have to include a bat file with my script and have the users set the location of mayapy.exe in order to use it. I would prefer to somehow package mayapy.exe with my script using something like py2exe. I'm a little lost on where to go from here honestly.
If I run py2exe normally on my script, its result gives me the error cannot find maya.cmds, as expected. Is there a way I can find the dll to include? I tried running Dependency walker on mayapy.exe but I'm venturing into new territory here. There were only 2 dll's used from the Maya install directory base.dll and python26.dll, the rest were all system dlls. If anyone has tried any of this please share or if anyone has any advice or path I can look down or a website I can go to I would be very grateful. Thanks so much!
P.s. In case it helps at all, this is the python script imports:
try:
import maya.standalone
maya.standalone.initialize()
except:
pass
import maya.cmds as cmds
import maya.mel as mel
from time import time as tTime
from glob import iglob
from shutil import copy
from os.path import join
from PyQt4 import QtCore
from PyQt4 import QtGui
The point of the script is to create a maya file, do some things in it, then save it. Using the maya interpreter(mayapy.exe) it does this without ever opening maya, which is what I was wanting.
Pretty sure what I wanted to do was not possible. Instead I split my program into two parts, one requiring Maya one not, for the part requiring Maya I just had it do a registry lookup for the Maya install location and used that. If it were possibly to include the necessary files for my script, I'm sure Autodesk would not have approved in the first place anyways.
I am trying to build an exe using PyInstaller (with Python 2.7) and have been stumped. My python code uses the modules wx, matplotlib, basemap (a part of matplotlib), and pylab. There are others, but these seem to be the main ones.
I have installed PyInstaller and then i did:
python pyinstaller.py C:/Python27/Convertthisfile.py
It goes through the whole process, but when i try to run the final executable, it comes up with the error:
"No module named PyQt4.QtCore"
I have installed PyQt GPL 4.9.1 for Python 2.7. However, I have no idea where PyQt is even being used in my code. I don't specify it anywhere that i know of.
Anyone have any thoughts? Nothing I do seems to work. I have even tried the GUI2EXE.py -- i can't get py2exe, pyinstaller, or cx_freeze to work.
HELP!
I have added my code below to hopefully help. To answer the comments, yes, my code is located in C:\Python27. I have no problem "building" it with pyinstaller, but the above error comes up when i try to run the given executable. I have searched the code and do not see any use of PyQt4.
When i run cx_freeze, i have issues with the basemap data files -- they do not seem to be included in the ".zip" when i build it. Also, none of my modules seem to get included either.
Here is what i import for my code (some of these functions are my own -- mainly the last ones listed).
import wx
import time
from matplotlib.backends.backend_wx import FigureCanvasWx as FigureCanvas
from mpl_toolkits.basemap import Basemap
from matplotlib.figure import Figure
from datetime import datetime
import wx.calendar as cal
import wx.lib.mixins.listctrl as listmix
from pylab import *
from decimal import *
import adodbapi
import annote_new
import cPickle as pickle
import calc_dist
import Game_Score
import Calculate_Distance
import Duplicate_Finder
import copy
Hopefully this clears things up?
