Issues with pyinstaller - python

I have created a working GUI program (using tkinter), but when I try to compile it using pyinstaller (py2exe only works for python 2.6 and I used 2.7 for the program), it doesn't work. I have 2 files: program.py, and data.xml. The program uses the xml document to retrieve information and display it to the window. I have looked all over, but no one seems to have had a similar problem, and the pyinstaller documentation is useless. the command I used was
python pyinstaller.py -w -mdata.xml -nProgram program.py
It appears to make the spec file fine, but generates an error with a large traceback upon build:
pyinstaller.utils.winmanifest.invalidManifestError: Invalid root element <items> - has to be one of <assembly>, <assemblyBinding>, <configuration>, <dependentAssembly>
and quits the build process. This is the first time I have tried to build an executable for a project, so I'm kind of shooting in the dark here. Did I forget to do something, or did I just find a bug in pyinstaller's program?

Normally I wouldn't answer my own question, but I have solved the issue and I think others should know about this. When creating your program and using an xml with it, you must have the root tag (the first one) as <assembly>. Not sure why, but it works when I do that. also, don't forget to use the --hidden-import=Module command if you imported anything into your program.

Tkinter program compiled with pyinstaller crash on launch

I'm asking help today because I'm new to Tkinter and Pyinstaller (and python in general) and I'm having troubles with it.
I have a simple app working with sqlite, tkinter and pyinstaller to compile all of this in an executable program, the entrance point of my program is a file named main.py
This file calls all the dependancies (like the sqlite module for python, tkinter and my other files like classes etc...)
I made a very simple interface, with a Hello World in a tkinter label and a button to go to page 2 which displays page2 (also in a label), just to see if I'm capable of making it all run and compile all of these pieces together.
I can run it throught my shell executing it like : python main.py and everything is working fine.
But when I run pyinstaller on my linux machine, and start executing the program, nothing appears, my database.db (sqlite database file) is created but I don't have any interface like when I run it with my shell. The thing is getting even worse on windows where, once I've my .exe it just opens a shell and crash after few seconds, not even creating the database.
What I did is I created a 'log file', in which I write the steps of the program.
As you can see on the following picture, the 2 first prints are wrote in my log file (on linux), so I think it crashes when I try to create the window.
If any of you have an idea on what I do wrong, I would really appreciate help :)
General
From the PyInstaller manual:
Before you attempt to bundle to one file, make sure your app works correctly when bundled to one folder. It is is much easier to diagnose problems in one-folder mode.
As the comments suggested, use a catch-all try/except block to log all exceptions to a file. That is probably the best way to see what is really happening. Make sure that the logfile is created in an existing location where you have the necessary permissions.
I would suggest to take advantage of the built-in logging module instead of creating your own. It can e.g. automatically add from which file a log line was created.
IMHO, it is probable that the failures on Linux and ms-windows have completely different causes. You should probably treat them as different issues.
Linux
When you use single file mode, that file is unpacked into a temporary folder, probably somewhere in /tmp. Some Linux distributions mount the /tmp filesystem with the noexec flag. This is incompatible with PyInstaller.
ms-windows
On windows, there are basically two different Pythons; python.exe and pythonw.exe. Basically it is one of the quirks of windows that this is necessary. The latter is for GUI programs like tkinter programs. A tkinter script should not show a cmd window. So I'm guessing that PyInstaller calls your command with python.exe instead of pythonw.exe. From the manual:
By default the bootloader creates a command-line console (a terminal window in GNU/Linux and Mac OS, a command window in Windows). It gives this window to the Python interpreter for its standard input and output. Your script’s use of print and input() are directed here. Error messages from Python and default logging output also appear in the console window.
An option for Windows and Mac OS is to tell PyInstaller to not provide a console window. The bootloader starts Python with no target for standard output or input. Do this when your script has a graphical interface for user input and can properly report its own diagnostics.
As noted in the CPython tutorial Appendix, for Windows a file extention of .pyw suppresses the console window that normally appears. Likewise, a console window will not be provided when using a myscript.pyw script with PyInstaller.
Also, on windows it can matter which Python distribution you're using. I used to be a fan of Anaconda, but lately I've come to prefer the python.org version because it gives me less headaches. On anaconda Python I had the problem that tkinter programs would not launch without showing a cmd window, whatever I tried. Only switching to python.org Python solved that problem.

Python: no module named 'bottle-websocket' when running an executable made with PyInstaller, including Eel module

I was playing around with the eel module for Python - gives an opportunity to run HTML + CSS/JS with the python functionality.
Made a simple program, tried to make an executable out of it via PyInstaller.
No errors whatsoever, but when running this executable it crashes on the first line - import eel, telling - there is no module called 'bottle-websocket'.
I checked pip: eel, bottle-websocket are installed. Can't figure out what's the problem. Attachments:
main.py:
import eel
from os import path
eel.init(path.dirname(__file__) + "/web")
eel.start('main.html', block=False)
while True:
eel.sleep(10)
Error:
Picture with the error while I try to start the exe
EDIT:
PyInstaller Log
I was also having this same issue, but I finally fixed it, it was actually very very easy, first of all make sure you are using auto-py-to-exe to package your app.
After inserting necessary details (script file,, extra files etc), you would see an advanced options tab probably below, click on it to expand it, look for the hidden imports label and insert "bottle-websocket" in the input field representing the hidden imports, that's basically all you need to do
I HOPE THIS HELPS
Took me the whole day figuring out the solution, but finally, here it is:
Copy the plugin.py, server.py files from C:\Users\YOUR_USERNAME\AppData\Local\Programs\Python\Python36-32\lib\site-packages\bottle_websocket to C:\Users*YOUR_USERNAME*\AppData\Local\Programs\Python\Python36-32\Lib
Make sure you have this line as follows in your *.spec file generated by PyInstaller (FOR PYTHON 3.6 32bit):
datas=[('C:\Users\YOUR_USERNAME\AppData\Local\Programs\Python\Python36-32\lib\site-packages\eel\eel.js', 'eel'), ('PATH_TO_YOUR_WEB_FOLDER', 'YOUR_WEB_FOLDER_NAME')]
3)Run this command in cmd: python C:\Users\YOUR_USERNAME\AppData\Local\Programs\Python\Python36-32\lib\site-packages\eel\main.py HERE_SHOULD_BE_THE_PATH_TO_YOUR_WEB_FOLDER
this command will get the 'bottle-websocket' work and will make sure that it complies with the web folder and files.

wxpython GUI program to exe using py2exe

I am new to python programming and development. After much self study through online tutorials I have been able to make a GUI with wxpython. This GUI interacts with a access database in my computer to load list of teams and employees into the comboboxes.
Now my first question is while converting the whole program into a windows exe file can I also include the .accdb file with it...as in I only need to send the exe file to the users and not the database..if yes how.
My second question is... I actually tried converting the program into exe using the py2exe (excluding the database...am not sure how to do that) and I got the .exe file of my program into the "Dist" folder. But when I double click it to run it a black screen (cmd) appears for less than a second and disappears. Please help me understand the above issue and resolve it.
am not sure if I have a option of attaching files...then I could have attached my wxpython program for reference.
Thanks in advance.

The console could possibly appear if you used the 'console' parameter to setup(). Switch to 'windows' instead if that is the case. Can't say for sure without seeing your setup.py script. Possibly your app could also be opening console, but again hard to say without seeing source. One thing to check is to make sure you are not printing anything to stdout or stderr. You might want to redirect all of stdout and stderr to your log just in case, and do this right at the top of your start script so that if some 3rd party import was writing to stdout you'd be able to capture that.
The db is not part of your executable, so py2exe will not do anything with it. However, you should probably package your application with an installer, and you can make the installer include the db and install it along with the executable.

running an ironpython script from python : sandbox, loadFromRemoteSources

I am kind of stuck with Iron Python now. All I want to do is to run an ironpython script from python. In my ironpython script I import a .net assembly called mydll.dll.
I thought of 2 ways to do this. The first one was to use pyc.py and make an exe file from the ironpython script. It did not work (I can't remember what was the error message but I remember wasting considerable time trying).
The second way I thought of recently was simply to call ipy.exe from my python script using subprocess.popen. Unfortunately it comes up with an error about "sandboxing" and "loadFromRemoteSources".
Here is the code that brings the error in my python script:
process = subprocess.Popen(["ipy.exe", "myironpythonscript.py"])
Here is what is in myironpythoncript.py:
from clr import AddReferenceToFile
AddReferenceToFile ('mydll.dll')
Does any one knows what's wrong?
OK I just figured it out.
It actually works, the thing is you need to add a config file called ipy.exe.config containing the following :
<configuration>
<runtime>
<loadFromRemoteSources enabled="true"/>
</runtime>
</configuration>
see here -> How do I setup configuration when I use command line to build C#/.NET?

git cannot execute python-script as hook

I have created a little pre-commit hook in python. This hook works like a charm under Linux, but in Windows it keeps telling me:
error: cannot spawn .git/hooks/pre-commit: No such file or directory
I know there have been similar questions here about the same issue and the conclusion seams to be the shebang. My script has this on the very first line:
#!F:\PortableApps\PortablePython3.2\App\python.exe
It's also interesting to note that executing the script simply by writing .git/hooks/pre-commit works wonderful, but as soon as I try to commit, git spits out the above message.
Another interesting thing is, when I convert the encoding from ANSI to UTF-8 (using Notepad++), I get the following error when trying to execute the script:
.git/hooks/pre-commit: Cannot execute binary file
I'm using the following tools:
PortablePython 3.2.1.1
msysgit 1.7.6 (Portable)
I used the proxy-approach to make the python script work under windows (with msysgit). The complete script (with description on how I did it) might be found here: https://gist.github.com/1839424
Here is the important part about making it work under Windows
If you're working with Windows (and "msysgit"), it's a little more complicated. Since "msysgit" seems to have a problem handling the SHEBANG, you'll have to use a little trick to make the script executable (further information on this problem can be found here).
In order to make the script work, you'll want to remove the SHEBANG from the Python script ("pre-commit.py") and use a wrapper bash-script to call the interpreter. This script should look something like this:
#!/bin/sh
python .git/hooks/pre-commit.py
Store this script as a file called "pre-commit" (no file-ending). This assumes that you have Python in your PATH. If you don't, you can also specify the full path to your interpreter-executable.
This script will be called by "git commit" and call the python-script to check for the huge files. The path after the SHEBANG should not be changed, as "msysgit" will remap it automatically. You must specify a path relative to the repo-root for the Python script to be executed (because thats from where the script is called).
Afterwards you'll want to copy both the wrapper-file ("pre-commit") and the Python-script ("pre-commit.py") to your repos ".git/hooks"-directory, personalize the Python-script ("max_file_size" and "git_binary_path") and mark the "pre-commit"-file executable.
