Unable to import module - python

I'd like to learn Python since it looks nice and I want to work with GTK. My previous experience with programming is Java and C# hardly a pain in the backside to deal with errors. However I am having problems with pythons py2exe and understand how to debug this problem. From what I can understand it probably a setup error relating to version types and file locations and not code.
I am running
Windows 7 64 bit
Python version 2.7.2 - 32 bit
pygtk-all-in-one-2.24.0.win32-py2.7
py2exe-0.6.9.win32-py2.7
All hyperlinks can be seen at http://pastebin.com/MNGPQVMP This is due to Stackoverflow only allowing me to post 2 links, but I've got a lot of information!
My problem is python executes my basic code fine with no problems, however using py2exe errors occur.
To produce the error I ran
python setup.py py2exe
In the list are both python files, the exe error log and the console output
PyApp.py > See main link
setup.py > See main link
PyApp.exe.log > See main link
Console output of running py2exe > See main link
For some extra information I ran
python -m py2exe.mf -d PyApp.py
python -m py2exe.mf -d setup.py
The output of both commands are listed below
python -m py2exe.mf -d PyApp.py > See main link
python -m py2exe.mf -d setup.py > See main link
from what I can understand from the exe error log and console output is it cannot import gio (is that part of glib?). And the extra module listings indicate other errors.
The gio error from the module lising of PyApp.py points to \Python27\lib\site-packages\gtk-2.0\glib\_init_.py This file contains
enter from glib._glib import *
_PyGLib_API = _glib._PyGLib_API
del _glib here
So it looks like something could be missing. However I'm not so sure
So how do I fix this import error?
Also as a side note, Dependency Walker is also stating missing 2 windows dlls.
http://localhostr.com/files/Gf1mXT3/Dependency_Walker..png
I have the DLLs however they are 64 bit and not 32 bit and if i place them in the directory then Dependency Walker flags the 64 bit error, but at the moment its clearly not the problem.
This comes across as a popular problem but I cant seem to work out how to fix it with the information I have got.

Very easy to fix! In your setup.py file, you should have a line something like this:
options = {
'py2exe': {
'packages':'encodings',
'includes': '<module names>',
}
},
In order to fix the error, simply add "gio" to the list of 'includes', like this:
options = {
'py2exe': {
'packages':'encodings',
'includes': 'gio',
}
},
I have a program built in pyGTK, so I have a number of modules I have to import. Just for reference, that code looks like THIS on mine:
options = {
'py2exe': {
'packages':'encodings',
'includes': 'cairo, pango, pangocairo, atk, gobject, gio, subprocess',
}
},

running python script as exe

I wrote a basic script in python 3.7 that does what I need. However it needs to run on another person's computer. I want to run this as an exe then just change the icon logo.
I have installed py2exe (I believe). Below is the python script:
pip install py2exe
import os
os.startfile(r"\\ComputerName\c$\users\UserName\desktop\Lullaby wav.wav")
I have another file, that looks like this (basing this off this thread Can I somehow "compile" a python script to work on PC without Python installed? ):
import sys
from distutils.core import setup
import py2exe
entry_point = sys.argv[1]
sys.argv.pop()
sys.argv.append('py2exe')
sys.argv.append('-q')
opts = {
'py2exe': {
'compressed': 1,
'optimize': 2,
'bundle_files': 1
}
}
setup(console=[entry_point], options=opts, zipfile=None)
I then open up cmd and try to use the compile.py file on myscript per the instructions but get an erro:
File "", line 1
python compile.py covid.pyw

You can use PyInstaller. Which is inbuilt, if not you can install it. Just very simple lines in cmd to create an exe file and also you can add icon using -i(I think so).
Visit this to learn about it from realpython which I love to read about python tutorials : https://realpython.com/pyinstaller-python/
By the way you can use python 3.8.6 or 3.9 which is the updated version of python 3.7.
Make sure your device is up to date, that could be the problem, also pyinstaller is a better, more modern alternative

failed to create executable with pyinstaller and cefpython on Linux (Invalid file descriptor to ICU data)

I have some simple cefpython code opening a url and am trying to create a stand alone executable with pyinstaller:
I copied files from https://github.com/cztomczak/cefpython/tree/master/examples/pyinstaller to a a directry named pyinstaller
I made following minor changes to pyinstaller.spec
+SECRET_CIPHER = ""
...
- ["../wxpython.py"],
+ ["../hello.py"],
...
- icon="../resources/wxpython.ico")
+ )
I can successfully compile my application on windows with python
On the same machine with python 3.5.4 64 bit and following virtualenv:
cefpython3==66.0
future==0.18.2
PyInstaller==3.2.1
pypiwin32==223
pywin32==228
I can also compile windows with python 3.6.4 64 and following virtualenv:
altgraph==0.17
cefpython3==66.0

PyInstaller==3.3.1
pyinstaller-hooks-contrib==2020.9
pypiwin32==223
pywin32==228
pywin32-ctypes==0.2.0
On Linux compilation works as well, but the executable is not operational.
I get following output and error:
CEF Python 66.0

version is python 3.5.2 64bit and the virtualenv is:
cefpython3==66.0
pkg-resources==0.0.0
PyInstaller==3.2.1
What could be the cause?
The code, that I try to compile is below:
import platform
import sys
from cefpython3 import cefpython as cef
def check_versions():
ver = cef.GetVersion()
print("CEF Python {ver}".format(ver=ver["version"]))
print("Chromium {ver}".format(ver=ver["chrome_version"]))
print("CEF {ver}".format(ver=ver["cef_version"]))
print("Python {ver} {arch}".format(
ver=platform.python_version(),
arch=platform.architecture()[0]))
assert cef.__version__ >= "57.0", "CEF Python v57.0+ required to run this"
def main(url="https://www.stackoverflow.com"):
sys.excepthook = cef.ExceptHook

cef.Shutdown()
if __name__ == "__main__":
main()
Addendum: 2020-10-14:
same error on linux with other versions:
so far I tried python 3.5 and 3.7
Is there anybody who successfully created an executable?
I could be, that this just an issue with the example project and its configuration?
As alternative, a solution could be found in PyInstaller bug 5400
Here the steps:
1- download the PyInstaller helper in CEFpython named hook-cefpython3.py from:
https://github.com/cztomczak/cefpython/tree/master/examples/pyinstaller and put in the root directory of your project
2- In that file, replace the line:
from PyInstaller.compat import is_win, is_darwin, is_linux, is_py2
with:
from PyInstaller.compat import is_win, is_darwin, is_linux
is_py2 = False
3- in your PyInstaller .spec file, add the '.' to the hookspath, e.g. hookspath=['.']. I think it is also possible to add it as PyInstaller command line option.
These steps should solve the problem, until CEFPython deliver a correct version of the hook file.
This is not really the answer I would like to accept, but it is at least one solution and contains information, that might lead to a better fix, a better answer.
After debugging with strace I found out, that the executable searches many files like for example icudtl.dat, v8_context_snapshot.bin, locales/* were searched in
'dist/cefapp/cefpython3but were copied todist/cefapp/`
An ugly work around is to do following after compilation
cd dist/cefapp/cefpython3
ln -s ../* .
and the executable works.
I'm sure there is also a nicer non-brute-force solution, but for the time being I wanted to answer in case others are stuck as well
Probably this can be fixed in the spec file but would we need one spec file for linux and one for windows then?
Perhaps there's also an option to tell the excutable to search for these files one level higer?
To solve this, you need to set this in your spec file:
hookspath=[r'YOUR_ENV_SITE_PACKAGES\cefpython3\examples\pyinstaller\']
And then rebuild, you will have things in the right place.
The following steps solved the issue for me on Windows 10, Python 3.9.5 32-bit, PyInstaller 4.3, and CEFPython 66.1:
Download the hook-cefpython3.py file from here and put it into your project root directory.
Run the pyinstaller command as usual but add the --additional-hooks-dir . command line option, so the command will look like this:
pyinstaller --additional-hooks-dir . <main-file.py>
As opposed to other answers here, this anser neither requires changes of hookspath directive in pyinstaller's spec file and, as of now, nor any changes to the downloaded hook-cefpython3.py file.

Cannot Include gi.repository.Gtk in py2exe

I have a project in Python 3.4 and GTK+ 3. I'm on Windows XP SP3 32-bit (VirtualBox).
I need to compile down to an executable using py2exe. (Do NOT suggest cx_freeze. It has ten times the problems on this project than py2exe).
My setup.py is as follows.
#!/usr/bin/python
from setuptools import setup
import py2exe
setup(name="Redstring",
version="2.0",
description="REDundant STRING generator",
author="MousePaw Labs",
url="http://www.mousepawgames.com/",
maintainer_email="info#mousepawgames.com",
data_files=[("", ["redstring.png", "redstring_interface.glade"])],
py_modules=["redstring"],
windows=[{'script':'redstring.py'}],
options={"py2exe":{
"unbuffered": True,
"compressed":True,
"bundle_files": 1,
'packages':['gi.repository'],
}},
zipfile=None
)
When I run it via C:\Documents and Settings\Jason\Desktop\redstring2>python setup.py py2exe, I get the following output (in full).
running py2exe
running build_py
1 missing Modules
------------------
? gi.repository.Gtk imported from __SCRIPT__
Building 'dist\redstring.exe'.
C:\Documents and Settings\Jason\Desktop\redstring2>
The actual script, redstring.py, runs without a hitch in my Windows environment. In that, I have the following (working) line of code: from gi.repository import Gtk That is ALL I import from gi.repository in the entire project.
If I swap the line in setup.py to 'packages':['gi'],, the error output switches to about 24-some-odd missing modules, all of them belonging to gi.repository. If I try and import "Gtk" or "gi.repository.Gtk" in either 'packages': or 'includes':, I get an error that the file in question being imported cannot be found.
I spent eight hours on #python (IRC channel) today, and no one could solve this. I need this packaged down to a Windows binary this week.
NOTE: This question is not a duplicate; while it is a similar issue, it is a) not the same error message, and b) neither answer solves the question in any way.
I solved this by, first of all, downgrading to Python 2.7. (GTK+ 3.8 is still fine.) py2exe apparently has known issues with Python 3.
Second, I switched...
options={"py2exe": {
"bundle_files": 1,
}
to
options={"py2exe": {
"bundle_files": 3,
}
For some reason, py2exe cannot include certain files needed to run the gi library when 'bundle_files' is set to 1 or 2.
The full setup.py that works with py2exe for my project can be found on GitHub. I run it on cmd with python setup.py py2exe.

Py2app keyflag error CFLAGS

What I'm trying to do is compile a program I've written in Python 2.7, using pygame, into a standalone app for Mac computers. I'm working on a PC running Windows 8 with no access to a mac, so tweaking the process has been difficult.
When I run the setup file from the command prompt, I get the "text flood" (similar to what py2exe gave me when it worked to compile the windows version) and the program appears to work. It creates build and dist folders, but the dist folder has no contents. When looking at the command prompt output, the last two lines are
BASE_CFLAGS = cfg['CFLAGS']
Key Error: 'CFLAGS'
This seems to happen when py2app is trying to create the application bundle.
Here is the setup.py file I've gotten to thus far:
"""
Script for building the example.
Usage:
python setup.py py2app
"""
from setuptools import setup
NAME = 'PetCute Slide Puzzle Test'
VERSION = '0'
plist = dict(
CFBundleIconFile=NAME,
CFBundleName=NAME,
CFBundleShortVersionString=VERSION,
CFBundleGetInfoString=' '.join([NAME, VERSION]),
CFBundleExecutable=NAME,
CFBundleIdentifier='Py2App and PyGam test',
)
setup(
data_files=['Dog1.jpg', 'Dog2.jpg', 'Dog3.jpg', 'Dog4.jpg', 'Dog5.jp', 'Dog6.jpg', 'Dog7.jpg', 'Dog8.jpg', 'Dog9.jpg', 'Dog10.jpg', 'Dog11.jpg', 'Dog12.jpg', 'Dog13.jpg', 'Dog14.jpg', 'Dog15.jpg', 'Dog16.jpg', 'AYearWithoutRain.ttf'],
app=[
dict(script="PetCute_slidepuzzle.py", plist=plist),
],
setup_requires=["py2app"],
)
The data_files lists out the pictures and text file that need to be bundled with the code. I got to this by adapting the alien.py example. Please let me know if any more info is needed!
It probably had an error during compilation. I suggest you make sure you have Numpy installed, its needed for py2app to compile Pygame programs.

Making exe using py2exe + sqlalchemy + mssql

I have a problem with making exe using py2exe. In my project i'm using sqlalchemy with mssql module.
My setup.py script looks like:
from distutils.core import setup
import py2exe
setup(
windows=[{"script" : "pyrmsutil.py"}],
options={"pyrmsutil" : {
"includes": ["sqlalchemy.dialects.mssql", "sqlalchemy"],
"packages": ["sqlalchemy.databases.mssql", "sqlalchemy.cresultproxy"]
}})
But when i'm starting procedure like:
python.exe setup.py py2exe
I'm receiving build log with following errors:
The following modules appear to be missing
['_scproxy', 'pkg_resources', 'sqlalchemy.cprocessors', 'sqlalchemy.cresultproxy']
And in "dist" folder i see my pyrmsutil.exe file, but when i'm running it nothing happens. I mean that executable file starts, but do nothing and ends immediately without any pyrmsutil.exe.log. It's very strange.
Can anybody help me with this error?
I know it's no an answer per se but have you tries pyInstaller? I used to use py2exe and found it tricky to get something truly distributable. pyInstaller requires a little more setup but the docs are good and the result seems better.
For solving this issue you could try searching for the mentioned dlls and placing them in the folder with the exe, or where you build it.
Looks like py2exe can't find sqlalchemy c extensions.
Why not just include the egg in the distribution, put sqlachemy in py2exe's excludes and load the egg on start?
I use this in the start script:
import sys
import path
import pkg_resources
APP_HOME = path.path(sys.executable).parent
SUPPORT = APP_HOME / 'support'
eggs = [egg for egg in SUPPORT.files('*.egg')]
reqs, errs = pkg_resources.working_set.find_plugins(
pkg_resources.Environment(eggs)
)
map(pkg_resources.working_set.add, reqs)
sys.path.extend(SUPPORT.files('*.egg'))
i use Jason Orendorff's path module (http://pypi.python.org/pypi/path.py) but you can easily wipe it out if you want.
