Pysimplegui: Issue with frozen mutiprocessing script is ran

[hpca01]

Hi Mike,

I messaged you about this issue on reddit, although I have found my workaround for it, using threads instead for my task.
Maybe in the future it might affect the ability to distribute scripts made from your package.
As usual i did it in a venv, modules in attached text.

Using Windows 10 64bit, Python 3.6

    #this is the long func call, of course as of right now it is a progress bar, 
    #but in place of it should be a normal function and a popup to indicate that it is done

    for i in range(20):
        sg.EasyProgressMeter("In Process code", i+1, 20)
        time.sleep(0.5)

    #So initially this is where the progress bar would show up, the func call to the 
    #another_long_func has already been profiled for example to last 10 seconds

    p=Process(target=another_long_func)
    p.start()
    for i in range(20):

I'm running Windows 10, 64 bit and only got crashes when I tried PyInstaller version 3.4

It seems to build OK, but I get this crash when I try and run the .exe

Would be AWESOME to get this to work. Then people could distribute .EXE files with a GUI!

Fatal Python error: Py_Initialize: unable to load the file system codec
LookupError: unknown encoding: utf-8

I believe the issue maybe related to PyInstaller, I will work on this to see if i can modify your module to be copacetic with the build system. 👍

[hpca01]

By the way this issue is non-existent with the following command:
pyinstaller test.py --onedir

hmm, maybe it will be the workaround, although it sucks. The issue revolves around how windows spawns processes in python.

[MikeTheWatchGuy]

PySimpleGUI.py is capable of running standalone. So, I typed this command:

pyinstaller pysimplegui.py --onedir

I still got the same error. And I still get a ton of info printed out when I do the build.

Really hopeful something's possible... this would be such a cool thing to be able to do!

Hmm can you make a venv and then run the test? Pyinstaller is heavily reliant on patterned searches for files in modules, maybe your re package is corrupt?

[MikeTheWatchGuy]

Which package are you thinking is corrupt? I uninstalled and reinstalled Pyinstaller with --no-cache-dir. The problem remains. Are there other pip install options I should do in order to get a cleaner install?

I do not currently have a virtual environment set up. What would you recommend that I run in order to do this under Windows 10?

I would like something that will allow me to easily text Linux and test python 3.4.

[hpca01]

it seems to be the re module

 File "c:\python\anaconda3\lib\re.py", line 142, in <module>
    class RegexFlag(enum.IntFlag):

I would try creating a small virtual environment for testing so that you can isolate the root cause. If you want i can upload my env and you can just run your tests on it.

[MikeTheWatchGuy]

@JorjMcKie managed to get a sample PySimpleGUI program built using nuitka!! 💯

I ran a PySimpleGUI.EXE file that he compiled. I've been unable to duplicate it using my setup. There are some tricky things to do in order to get tkinter working with nuitka.

If Jorj can work out the problems then we'll have an _amazing solution available for Windows users_!!! I'm SO looking forward to being able to give my Python programs to my friends that are not running Python. It opens up all sorts of opportunities

[hpca01]

Nice! I've been eyeing that library too, did he give you a link to his build script?

[MikeTheWatchGuy]

It's happened!

@JorjMcKie and I have both compiled programs that use PySimpleGUI and they make an exe file (and folder full of stuff) that runs the program. I tried Pong as a performance and compat challenge and it worked perfectly!

Damn, this is a big damned deal. I'm working to get the instructions published.

[MPoppinga]

Even if a nuitka solution is approaching,
I just want to note, that i'm using PySimpleGUI without any problems using pyinstaller (3.4).

"pyinstaller.exe script.py -w" using Windows 10 and Python3.7.0(Anaconda) creates in my casse a working exe file.

[MikeTheWatchGuy]

Awesome!
I wish I could join the fun and run with pyinstaller too.

I had not tried the -w flag. I tried it and managed to get a .EXE that didn't crash. It just didn't do anything at all.

I'm running Windows 10, anaconda 3.6.

[MPoppinga]

Did you try the -F option (creating only one .exe file)?

But it sounds more like an issue with your Python installation.
Du you have the deprecated enum-backport/enum34 package installed?

Otherwise you could try to update your python to 3.6.5 or 3.7.0 via conda and create a clean conda env.

[hpca01]

@MrSunday334 have you tried to do it as onefile??

[MPoppinga]

Yes, this works also without problems (under windows10 /py3.7) using only one file, although it needs ~2 seconds to start.

I have noticed that the program crashes if I build it with python3.6.6 instead of 3.7.0. But this may be a problem of my environment. But also in this case, the packing itself is without problems.

On Linux(Fedora/Gnome/Wayland), the software crashes regardless if I build a executable or not, as soon as the second window should be shown.

[MikeTheWatchGuy]

I'm currently running 3.6.2.

Perhaps this explains my crashing??

I have not tried the -F option.

While I'm running Conda, I never change my environment.

Part of my feet dragging is that I fear messing up the environment that's taken many months to get right.

I am unsure how to upgrade my Python in general. Can someone give me some advice?

[MikeTheWatchGuy]

Tried -F and -F -w. -F alone gave me the same "crash" as I had before.

Running with -F and -w did nothing but return to the command prompt after a couple seconds.

I feel like I'm getting "close" would be awesome to get this to work... just plain awesome

[MPoppinga]

You can either create a new conda environment via PyCharm or the console.

To create a python3.7 environment the command would be conda create -n envname python=3.7
You can update components (including python) with conda update -n envname packagename

In most cases, I manage my environment via pycharm, but as anacondas main package ist only released for 3.6, I go with the console to create a Python 3.7 environment. But you can also go with python3.6 after I fixed the dependencies for pyinstaller it also runs flawless in python3.6.5 .

Best practice is to create a new environment (via pip or conda) for each project.
with conda list or conda list -n envname you can see which packages are currently installed.

In the best case you only have the packages you require in your environment.
As far as I see this would only be pyinstaller for the PSG, or do you have further dependencies, which I am missing?

so using the anaconda prompt:

conda create -n psg
conda activate psg
conda install pyinstaller
(python -m pip install PySimpleGUI) or using local codebase
pyinstaller test.py -wF
.\dist\test.exe

[MikeTheWatchGuy]

Will try these. Thank you for posting them and working on this.

Side note - I have been running the Nuitka compiled CPU Widget for over a day and it's rock solid. No errors, no memory leaks, pure .EXE bliss.

I'm dying to get PyInstaller working as another option. Running an EXE is SO cool. My skeptic non-Python programmers are sitting up and taking notice.

[MikeTheWatchGuy]

I entered all the nicely typed up Conda instructions.

I compiled a couple of different .py files and both had the same outcome. I get a bunch of stuff output during the built process. When I run the .EXE file, nothing happens except a spinning cursor for about seconds.

Here is the output from my build.

Are you sure the newly created env is activated?
In this case, the prompt would read(psg) C:\Users\Mikeinstead of(base) C:\Users\Mike

I'm confused as it seems that anaconda tries to use the base environment and is also not updating python.

Can you enlist the output of "conda list" in your env?
It should be like:

(psg) C:\Users\Martin>conda list
packages in environment at C:\Anaconda3envs\psg:

Name Version Build Channel
altgraph 0.15 py_0 conda-forge
certifi 2018.8.24 py36_1

macholib 1.11 py_0 conda-forge
pefile 2018.8.8 py_0 conda-forge
pip 10.0.1 py36_0
pycrypto 2.6.1 py36hfa6e2cd_9
pyinstaller 3.3.1 py36_vc14_0 [vc14] conda-forge
PySimpleGUI 3.3.0
python 3.6.6 hea74fb7_0
pywin32 223 py36hfa6e2cd_1
setuptools 40.2.0 py36_0

wheel 0.31.1 py36_0
wincertstore 0.2 py36h7fe50ca_0
zlib 1.2.11 vc14_0 [vc14] conda-forge

Further, you can try to update (inside your environment) conda update --all

Btw. you could test it in a VM, as its also working for me with fedora and ubuntu.

It's super weird that it worked for me right out-of-the box and I cant even reproduce this error.
For this particular error I found https://stackoverflow.com/a/45716067

@MrSunday334
Quick question, I know that OS determines how the subprocess call with be executed, but I have noticed on widows, when I call subprocess command with args I get an infinite loop of the first window popping up again even though it should be exited. Is this attributed to the os.fork method in windows?

Are you able to test on a windows os if you have a comp with it? I have tried it with different venvs by only going with the least required one. I would like to make sense of this before i try to distribute any apps. If i really have to upgrade to 3.7 to avoid those issues, lol i mean what the hell why not.

You are correct, the activate fails... I looked it up... I needed to do an activate psg

I had the same results unfortunately

Ah, yes, we got a little aside from the topic of the issue.

@MrSunday334
Quick question, I know that OS determines how the subprocess call with be executed, but I have noticed on widows, when I call subprocess command with args I get an infinite loop of the first window popping up again even though it should be exited. Is this attributed to the os.fork method in windows?

Not quete sure about the techical fallpits between the different os, espeacily not with freeze_support(), but the behavior should remain the same.

Are you able to test on a windows os if you have a comp with it? I have tried it with different venvs by only going with the least required one. I would like to make sense of this before i try to distribute any apps. If i really have to upgrade to 3.7 to avoid those issues, lol i mean what the hell why not.

The problems I had with 3.6 were self-made (no pyinstaller for 3.6 installed ... d'oh) so it works for me under Windows 10 without problems. If I hit cancel the second task pops up if not, the tasks ends, correct?
I got problems under linux but this is probably an other issue.

This works so far independent whether I pack it with pyinstaller or not.

Have you tried to create the env as I described before, under this configuration it's working for me?
maybe you can python -m pip install pyinstaller to get the 3.4 pyinstaller version, instead of 3.3 which is bundled in anaconda.

[MikeTheWatchGuy]

Perhaps this enum attribute error thing may be causing the problem? Do others get this same erro?

It shows I'm running Pyinstaller version 3.4
python -m pip install pyinstaller

[MPoppinga]

You are correct, the activate fails... I looked it up... I needed to do an activate psg

I had the same results unfortunately

ok, next try..

maybe you can try to install pyinstaller also via pip
python -m pip install pyinstaller
(and remove in doubt th anaconda version)
this gets you version 3.4 of pyinstaller.

Perhaps this enum attribute error thing may be causing the problem? Do others get this same error?

Yes, but it seems that there an deprecated enum34 module was installed

It's super weird that it worked for me right out-of-the box and I cant even reproduce this error.
For this particular error I found https://stackoverflow.com/a/45716067

What does conda listsay?

[MikeTheWatchGuy]

(psg) c:\Python\PycharmProjects\GooeyGUI\pyinstaller\dist>
(psg) c:\Python\PycharmProjects\GooeyGUI\pyinstaller\dist>conda list
# packages in environment at C:\Python\Anaconda3\envs\psg:
#

[MPoppinga]

no packages? Thats weird.
try to install pyinstaller and PSG via pip or conda

[MPoppinga]

Otherwise try to call pyinstaller directly:
C:\Python\Anaconda3\envs\psg\Scripts\pyinstaller.exe -w file.py

[MikeTheWatchGuy]

I did the pip installs and they all say requirement met.

I uninstalled pysimplegui and reinstalled and the conda list was still empty

[MikeTheWatchGuy]

There is no exe in that folder... there is only .bat files

[MikeTheWatchGuy]

I did this and still bad looking output and exe did nothing
C:\Python\Anaconda3\Scripts\pyinstaller.exe -w Demo_All_Widgets.py

THIS IS SO FRUSTRATING

It's ALMOST as frustrating as trying to setup (and failing) a shared folder using VirtualBox

[MPoppinga]

As long the error with the enum is there pyinstaller will not create a wellformed output. The question is why your environment is... special.

Is there a way to contact you more directly, than chatting in a Github issue?

[MikeTheWatchGuy]

sure! Email me and I'll give you my phone number.

My environment... SUCKS

of course my email is....

[MikeTheWatchGuy]

IT WORKS!!!

Thank you SO MUCH for the live help @MrSunday334 !

All I had to do was uninstall enum34 and it all suddenly works!

I created a single .EXE file for one of the demo programs and it was only 9 MB in total with only 1 file needed. THAT is amazing!

I cannot wait to document this!!!!

Now anyone can easily write a windows program with a GUI

[MikeTheWatchGuy]

pyinstaller -wF my_program.py

This is the magic line to enter to turn your PySimpleGUI program into a single .EXE file that you can distribute.

[MikeTheWatchGuy]

Are the instructions for creating a .exe from a PySimpleGUI based program really this simple?

Do these only once

Install PyInstaller

pip install pyinstaller

Install PySimpleGUI

pip install pysimplegui

Write your PySimpleGUI program

Use PyCharm or another IDE to create your GUI program
Test it out on Windows

Compile your program into a .EXE file

pyinstaller -wF yourprogram.py

yourprogram.exe will be in a subfolder named dist

Distribute your yourprogram.exe to anyone running windows

[hpca01]

hmm I use a spec file, usually it depends on the dependencies you have within your script. So now that you can make the exe can you try the script that I put up early in the thread?

[MikeTheWatchGuy]

OK, I fixed up the code... it ran both as a.py and a .exe

One thing you cannot do is run more than 1 EasyProgressMeter at a time. This is why I wrote OneLineProgressMeter. But that's not the point of your post.

It worked great. I'll see if I can work it into the code that is causing my multi-threaded crash.

[hpca01]

You rock dude! I would like to certainly learn from you how did you decide to structure your lib?

[MikeTheWatchGuy]

Thanks for the compliment! I'll take all of those I can get!

how did you decide to structure your lib?

Structure which part? The overall structure is a _mess_ in my opinion. The .py file is now > 4800 lines of code.

When I started, a few months ago, I was learning Python. PySimpleGUI was one of my first programs.
