I'm working with py2app on Python 2, and was wondering if there's a way to detect from code whether my app is running as part of a compiled .app file, or as a standalone script.
This is important because some of my code dynamically loads a .dylib file. When running natively as a script, this code runs fine; however, when running inside the .app, I get something like:
Traceback (most recent call last):
File ".../python/game/dist/main.app/Contents/Resources/__boot__.py", line 316, in <module>

I'm thinking the best way would be to move the .dylib file outside of the library and into the Resources, then dynamically load it from there - but in order to do this I need to detect in code whether I'm running in the .app or not, and if so, look in a different location for the library (namely, the Resources folder of the app bundle)
Help appreciated!
Py2app sets sys.frozen to "macosx_app" (for application bundles).
A way to avoid your problem is to use the "packages" option:
setup(
...
options={
'py2app': {
'packages': ['audio'],
}
}
)
This includes the entire "audio" package in the application bundle as a directory instead of adding it to the site-packages zipfile. That way you don't have to detect whether or not you're in a application bundle.

I have been getting above error. Could some one please tell me how would i fix it?
The problem seems to be related to this github issue, essentially the skimage.io._plugins submodule is making life hard for Pyinstaller.
To make sure everything you need is packaged you should have a hook file that contains
from PyInstaller.utils.hooks import collect_data_files, collect_submodules
datas = collect_data_files("skimage.io._plugins")
hiddenimports = collect_submodules('skimage.io._plugins')
(or if you already have a hook file with these, extend the current datas and hiddenimports).
I have been running in circles trying to figure out how to get my Django app to recognise the trial version of PDFNet:
https://pypi.python.org/pypi/PDFTron-PDFNet-SDK-for-Python/5.7
I tried adding the files to my ~/usr/bin directory, I tried dropping them into my virtualenv's bin directory. Neither has worked. I have read all the documentation i can find. I am too new of a Python developer to look at this package and know how to install it and utilize it in my project.
Please help!
update I attempted to create an app folder, and list this component as an app in the app list, but when I run the code to start the application, I get the following error:
Library not loaded: #rpath/libPDFNetC.dylib
I placed all of the lib files into this folder within my project:
__init.py (empty)
_PDFNetPython.so
libPDFNetC.dylib
PDFNetPython.py
PDFNetRuby.bundle
I used the following import code at the top of the py file I was attempting to use the component on:
import site
site.addsitedir("../pdfnetc")
from pdfnetc.PDFNetPython import *
I put the lib files into a app folder named pdfnetc. once I had this, the import statements were no longer listed as unfound by pycharm.
here is the stack trace:

home page link here
Below are steps to install the PDFNet module:
Download the Python and Ruby prebuilt binaries. Make sure you download the right architecture for your Python interpreter.
Extract the downloaded zip file and navigate to it.
Navigate to the /PDFNetC/Lib directory of the Python SDK download and execute:
> chmod a+x fix_rpaths.sh
./fix_rpaths.sh
I am not knowledgable of django, but take a close look at the sample py files that are in the SDK. For example, take a look at PDFNetC/Samples/AddImageTest/PYTHON folder. In there is a .py file, and look at the first 4 lines of code, they indicate what needs to load.
Please note that you need all the files that are in PDFNetC/Lib folder, including the PDFNetC.dll file.
If this does not help, please post the exact (first) error message you get.
It just works fine for me when i try to run the shell script, btw iam using the python as my programming language for pdfnet,
Try to use these commands to run the pdfn
#!/bin/sh
TEST_NAME=PDFATest
export LD_LIBRARY_PATH=../../../PDFNetC/Lib
python -u $TEST_NAME.py
The PDFATest specifies the python code, and then the export will get the required packages such as the PDFNet which is in
../../Lib
folder so make sure you use that file in the lib and then run your code and you will not have any issues with PDFNet, btw i dont answer this with respect to django but sure this will help you out.
I don't know what changed, but suddenly none of my Python App Engine projects will start on my PC. They start on my MacBook just fine, so there's something about the installation on my PC that's messed up. I've tried going back to 1.8.8, but that doesn't work. I've also tried using a fresh Python installation, but that didn't work. I've even tried using port 8080 (I usually use port 80, as I run the app launcher as admin).
This is what shows up in the error log when I click start on one of my projects:

Also, I'm using Windows 7 x64. My original installation of Python is from Enthought x64, but I did try using the basic x64 Python as well. As mentioned, I downgraded from 1.8.9 to 1.8.8, to no avail.
From a quick Google search, other users are suggesting it's a bug in pyvenv. Since not very many people are still using CherryPy, and it seems to only manifest itself in whatever CherryPy is doing there, that's probably it.
Bug the gist is that somewhere, only on Windows, you have a pydoc.py file which is being imported instead of the standard library's pydoc file.
So, find the offending pydoc.py file in your import path, and rename it. You can most likely find it by doing something like this:
import pydoc
print pydoc.__file__
I am trying to create an executable of my Python application that uses PyGTK to make a GUI. I have a well-established, automated build process using Pyinstaller that has worked for me for a previous application. Suffice it to say that it calls the usual Makespec.py and Build.py with 32-bit Python 2.7, with Pyinstaller configured for 32 bits. The resulting 32-bit application works fine on my machine and another machine running Windows 7 64-bit, but fails on 32-bit Windows XP with this error:
C:\OutNav_0_64\OutNav_0.64>outnav
Traceback (most recent call last):

ImportError: DLL load failed: The specified procedure could not be found.
The strange part is, there is no C:\Pyinstaller-1.5 directory on my machine or the one experiencing the error. I have no idea why it is attempting to run code from this nonexistent directory, or what the missing DLL is. Can anyone help me fold PyGTK into my application?
NOTE: The first line of the trace, line 23 in my program, is
import gtk
UPDATE: My manager successfully ran it on 64-bit Windows XP.
UPDATE 2: He was mistaken, it was 64-bit Windows 7. It has the same problem on his Windows XP installation.
Also, on the original machine it failed on, from the directory of the executable, I did this:
>>> import imp
>>> fp = open('gtk._gtk.pyd', 'rb')
>>> mod = imp.load_module('gtk._gtk', fp, 'gtk._gtk.pyd', ('.pyd', 'rb', 3))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: DLL load failed: A dynamic link library (DLL) initialization routine failed.
As far as I can tell, the .pyd file (which is in the format of a .DLL file) generated by pyinstaller on Windows 7 is incompatible with Windows XP. My solution was to simply recreate my build process on a Windows XP machine, which solved it to my satisfaction.
I am trying to create an exe file from my program written in Python 2.7 (using GTK+ layouts). I have consulted this guide: http://www.py2exe.org/index.cgi/Py2exeAndPyGTK and tried to set up my files accordingly. I succesfully make an .exe file, but when trying to run it, i get this error:
Traceback (most recent call last):
File "cipherka.py", line 183, in <module>
File "cipherka.py", line 18, in __init__
GError: Nelze otevřít soubor "C:\Repa\cipherka\dist\library.zip\gui.xml": No such file or directory
While I cannot find the gui.xml file in the library.zip archive, it is available on the same level as the main .exe (cipherka.exe) file. If i copy it into the .zip file on my own, it doesn't solve the problem.
Here is my setup.py file:
from distutils.core import setup
import py2exe
import glob
setup(
name="cipherka",
windows = [
{
'script': 'cipherka.py',
}
],
options = {
'py2exe': {
'packages':'encodings',
'includes': 'cairo, pango, pangocairo, atk, gobject, gio',
}
},
data_files=['gui.xml',
'README',
("modules", glob.glob("modules/*.*")),
("media", glob.glob("media/*.png"))
]
)
Any help will be wildly appreciated! And I can give you any necessary info when needed. Thx
UPDATE:
Allright, I implemented the change. However, it does weird things. When i use:
path = os.path.dirname(__file__).replace('\\library.zip','')
it works when ran from the .py file, but fails when compiled with this error:
Traceback (most recent call last):
File "cipherka.py", line 217, in <module>
File "cipherka.py", line 18, in __init__
NameError: global name '__file__' is not defined
When i use
path = os.path.dirname('gui.xml').replace('\\library.zip','')
instead - the program stops running from python and the compiled version gives me the following:
C:\Repa\cipherka\dist\cipherka.exe:188: GtkWarning: gtk_tree_path_append_index: assertion `index >= 0' failed
C:\Repa\cipherka\dist\cipherka.exe:188: GtkWarning: gtk_tree_model_get_iter: assertion `path->depth > 0' failed
Traceback (most recent call last):
File "cipherka.py", line 217, in <module>

Any ideas?
"gui.xml" is in "C:\Repa\cipherka\dist\", not "C:\Repa\cipherka\dist\library.zip" as your code supposes.
This should work whether your program is compiled or not.
path = os.path.dirname(__file__).replace('\\library.zip','')
xml_file = open(os.path.join(path, 'gui.xml'))
the error reported is due to scripts running under py2exe do not have a __file__ global. Detect this and use sys.argv[0] instead in your .py file.
