Generate an executable file in python - python

I have proceeded to generate an executable file using pyinstaller, once it has finished the corresponding files are generated, then:
In my windows console I apply this command: pyinstaller --onefile program_with_excel.py
I use this command to compile everything into a single.exe file, so that I can use it on another pc.
Once this is done, I open my executable located in the 'dist' folder and when doing so I have detected several problems:
My executable file 'program_with_excel.exe' is too heavy for what I am trying to do, a few simple calculations. (317,948 KB)
When I open it, the following error appears and then my application closes:
I suspect it is because to run my program I use an excel sheet using 'pandas' where I place data and they are calculated with my program. How could this be resolved?
What would be the solution for this problem and be able to work with my executable?
I also attach a rar with my program and my excel sheet: RAR_EXAMPLE
Best regards.

The exe needs to have access to all its dependencies, just like the python script. If you moved it then it may not have that access. It appears from the error that this is the problem. A common way these exe files are transported is by putting it and each dependency in a zipped folder and using NSIS.

Creating an executable kivy app and exe installer

I created a data-miner GUI for twitter with kivy and am currently having a lot of trouble turning it into an exe. I tried following this video and import glew and sdl2 into my spec but after doing pyinstaller main.spec, my executable still would not open.
Is it because I have more than one files and folders for my program (here is the link to the github repo for my project), if so, how do you deal with that?
In addition, if I manage to success create a working exe, how do I create an exe installer that other people can use to install the executable?
Making an executable from a complex script like yours may become quite frustrating because of its dependencies. But I'm giving you a brief guide about what you need to follow to achieve your goal.
Create your main.spec file with console-mode enabled to see the exact error message for the app. (make sure to remove --noconsole from PyInstaller command or set console=True in spec file). Also use --no-upx in the build command to remove compression from output file (this helps with omitting some DLLs which may cause issues).
You need to make sure that every external module you used can pack correctly. I don't think you get any problem with either Kivy or Tweepy. But if you get any missing import error, try to check the solution for each one by searching the pattern [module] pyinstaller.
Your app has external resources like images, files, etc., which must be added to the packed executable and load properly. I wrote an answer about this here.
If you want a standalone executable, you need to use -F with PyInstaller command, which is more robust than using an installer to gather files in one directory mode.

Sending Python .exe file to a machine without Python

I've created an executable file using cx_freeze that contains a simple Python script. The .exe file works on my PC (I have Python installed) but is it possible to send it to a colleague, for example, that doesn't have Python on their machine and will it work? The goal is to package useful Python programs and make them available for others to use even if they don't have Python.
I've played around with it a little bit and it doesn't seem to work on non-Python enabled machines. I've sent just the .exe file (didn't work), just the 'build' folder (in a zip file-didn't work) and I've even zipped the whole folder that contains the .py files and the build folder-that also didn't work. However, I thought this was the point of creating the .exe file? Any guidance would be appreciated.
Thanks

Pyinstaller exectuable using data from other folders?

I've written a program that generates a random name and displays a random image along with it using Python and tkinter. However, I want the user to be able to add and remove pictures as well as edit the names of students. That being said, I don't want to package these inside the executable where it can't be changed by the user.
To use PyInstaller, I go into the command prompt and navigate to the working directory and type:
pyi-makespec --windowed --onefile --icon=Assets\\icon.ico random_student.py
Then, in the spec file I change datas to:
datas=[('Assets\\icon.ico', 'Assets')],
Then, I run
pyinstaller random_student.spec
The program runs just fine using PyCharm. And I've done this exact same method on a couple of other .py files an it works. However, they don't need to pull images/text into their programs. This will create an executable, but I can't run it. It gives me a Fatal Error "Failed to execute script random_student". I've tried placing the executable in the working directory and in the pictures folder, but neither work.
I'm currently using Windows 10 64-bit and Python 3.6.6
I'd appreciate any kind of help I can get with this!
SOLUTION: I removed the --windowed option so I could actually read the error. Then realized I didn't have Pillow installed so it was unable to be packaged. Thank you for the help.

pyinstaller exe without any dependencies?

So I'm using pyinstaller with python27, and my exe works great so long as it's in the same directory as the build folder. I need it to be a completely standalone exe, without any dependencies, is there a way to bundle the important things from the build folder into one file? Neither -F nor --onefile seems to do this.
Edit: as I explain in my answer below, I thought pyinstaller was the problem because the exe would only run in the dist folder, so I assumed it had dependencies there, but in reality, it was running and then instantly crashing due to a bug that only triggered when the exe was on the desktop.
I figured out that the reason it wasn't working had nothing to do with pyinstaller or dlls. The exe was opening, and and trying to input powershell commands via python like it was supposed to. Unfortunately I had a line of code that said this:
subprocess.check_output('schtasks /create /sc minute /mo ' + str(time) + ' /tn "test_process_to_run_every_'+str(time)+'_min" /tr //'+sys.argv[0],shell=True)
#set this exe to run every X minutes in windows scheduled tasks
the problem was that sys.argv[0] changed when I put the exe on the desktop, and ended up being a path that looked like C://Users/John Smith/Desktop. The space in between John and Smith made powershell mad and crashed the program, so I escaped it using this line of code:
path = sys.argv[0].replace(" ","^")
and then I replaced sys.argv[0] with my new path variable. Hope this helps anyone in the future trying to do the same thing.
after pyinstaller has converted your script into .exe, than you need to add the executable to path, otherwise you have to open the command line in the directory that the file is in. pyinstaller just puts your script and py interpretor into a single file. same goes for linux.
for dependency side, look here.
there are other options you can try to bbFreeze, py2exe, cx_Freeze
to use pyinstaller in a simple way:
pyinstaller --onefile your_file.py
now you should see couple of files build, dist(exe in here).
NOTE: that --onefile flag doesn't necessarily get rid of the need for it to have link with certain libraries, it will still need those in order to run.
prepare for distribution, first need to get a spec file:
to get a spec file:
pyinstaller --noconsole your_file.py
than you can get the exe file for distribution like so:
pyinstaller your_file.spec
for more info and tutorial look here
see if nuitka works for you, it might sound scary but it is not. it compiles your code to executable binary format. Be aware that under the hood first it converts to c++ API calls.
if you dont like that for closed source program use Cython, and for no dependency use py2exe

Cannot find output folder for .exe file using pyinstaller

I am completely new to python and trying to create an application (or .exe) file for python using pyinstaller. I ran the command pyinstaller -[DIRECTORY].py and it saved it to an output directory "C:\Windows\System32\Dist\Foo", however when i tried to locate the directory it did not seem to exist (Dist).
NOTE: i'm trying to convert a .py file to .exe file in Python 3.5
Thanks for any help :)
If you set your command directory to the .py script location and run pyinstaller yourscript.py, it will generate folders in the same location as your script. The folder named dist/ will contain the .exe file.
Could you please try easily the command:
`pyinstaller yourscript.py`
You will get your output folder anyway if everything is correct with your software/module.
Second you can have no rights into System32 folder, so you could try a different folder.
Third you might have inconsistency with the path \ or /.
Hope those three suggestions will lead you to the correct solution :-)
Have a nice day.
