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.
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from scipy.fft import fft as fft
from scipy.fft import ifft as ifft
from tkinter import *
from tkinter import ttk
from tkinter import simpledialog
from tkinter import filedialog
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
I wrote a GUI, for which I used these imports:
import os
import sys
import serial
import scipy
import string
import time
import datetime
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
from collections import deque
from numpy import array
from pylab import xlabel, ylabel, subplot
from scipy.fftpack import fft
from pylab import *
There is a red line below sys and time, I am using pycharm community edition 4.5.3, it is showing the reason for this error is 'no module named sys' and same for time.
But when i tried to run it, it works perfectly.
What is the reason behind it and will it affect my code in future?
Change the python interpreter from python to python2.7. It's helped me.
This is something I just ran into with Intellij 2017.3.4 where it could find every module except sys and time in the editor, but everything would run fine. I had both 2.7 and 3.5 version of python and it did not seem to matter which one I selected as the SDK. I tried adding and removing them.
When I went to Project Structure -> Platform Settings -> SDKs -> Python 3.5 -> Packages it prompted a warning that Python packaging tools not found. and had an install link. I installed it and the editor no longer complained about sys and time. When I switched SDKs to 2.7 (without installing the packaging tools) it complained again.
So I am not exactly sure what is happening that that seemed to fix it for me it other people run into this problem.
I was having issues getting the scikit-learn module to import into python. It would import into the python shell, but not when I did it through my IDE. After reading lots of things online, I got it to work by using:
import sys
sys.path.append(r"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages")
import sklearn
Does anyone have a suggestion so that I don't need to do the sys thing every time I want to use the module?
In your IDE, find where you can change the "Python interpreter" setting, and point it to /Library/Frameworks/Python.framework/Versions/2.7/bin/python
I used py2exe to make an exe of my Python script but when I run the exe file it gives me matplotlib data file missing error. What can I do for this thing?
Also I tried using pyInstaller but when everything was completed there was a run time error saying that application failed to start side by side configuration pyinstaller.
I am importing these files in my Python script:
import cv2
import numpy as np
from SimpleCV import *
import SimpleCV
import random
import time
Is there some workarounds or a proper solution I need it badly!
There are some workarounds and information for several modules on py2exe website. For matplotlib check this
import matplotlib
...
setup(
...
data_files=matplotlib.get_py2exe_datafiles(),
)
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
