Max recursion occures and fixed .spec file doesn't work

[dsaylikoglu]

I wrote a python program using tkinter and sympy. However, when i try to turn it into a .exe file, pyinstaller gives me a recursion error and tells me to change something on the .spec file and try with that file. Unfortunately, when I write import sys ; sys.setrecursionlimit(sys.getrecursionlimit() * 5) on top of the .spec file, that also doesn't work. Please help me!! I couldn't find anything about this online. You're my last hope..

add --log-level=TRACE and post the output to a gist.

[dsaylikoglu]

it says 'utf-8' codec can't decode byte 0x87 in position 123: invalid start byte

[bwoodsend]

What's the command your giving to pyinstaller?

[dsaylikoglu]

pyinstaller.exe --onefile --icon=lim.ico -w limit_calculator.spec --log-level=TRACE

[bwoodsend]

None of those options do anything when using a spec file but that shouldn't matter. What's the contents of the limit_calculator.spec?

[dsaylikoglu]

# -*- mode: python ; coding: utf-8 -*-
import sys ; sys.setrecursionlimit(sys.getrecursionlimit() * 5)


block_cipher = None

Looks like this really is unicode related and not just a red herring. Could you try moving your code to a folder which doesn't contain any çs or any other non ascii characters? Also, what is your codepage (run chcp in cmd)?

[dsaylikoglu]

My active code page is 437.

[xoviat]

first of all, what is the stack trace for the error 'utf-8' codec can't decode byte 0x87 in position 123: invalid start byte?

[bwoodsend]

That ç is the culprit.

>>> "ç".encode("cp437")
b'\x87'
>>> "ç".encode("cp437").decode("utf-8")
Traceback (most recent call last):
  File "<input>", line 1, in <module>
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x87 in position 0: invalid start byte

I suspect that whatever text editor you use has converted the spec file to your native encoding instead of leaving it as utf-8 as at should be. You'll have to work out how to change it back which depends on which text editor you're using.

[dsaylikoglu]

i changed the unicodes chars to ascii characters. still not happening. i ran the command in a pc and it works. i guess my pc has sth wrong ones again

[bwoodsend]

Full traceback please.

=============================================================
A RecursionError (maximum recursion depth exceeded) occurred.
For working around please follow these instructions
=============================================================

1. In your program's .spec file add this line near the top::

     import sys ; sys.setrecursionlimit(sys.getrecursionlimit() * 5)

2. Build your program by running PyInstaller with the .spec file as
   argument::

     pyinstaller myprog.spec

3. If this fails, you most probably hit an endless recursion in
   PyInstaller. Please try to track this down has far as possible,
   create a minimal example so we can reproduce and open an issue at
   https://github.com/pyinstaller/pyinstaller/issues following the
   instructions in the issue template. Many thanks.

Explanation: Python's stack-limit is a safety-belt against endless recursion,
eating up memory. PyInstaller imports modules recursively. If the structure
how modules are imported within your program is awkward, this leads to the
nesting being too deep and hitting Python's stack-limit.

With the default recursion limit (1000), the recursion error occurs at about
115 nested imported, with limit 2000 at about 240, with limit 5000 at about
660.

[xoviat]

You need to add --log-level=TRACE to the PyInstaller command. And if you run into unicode errors, you need to fix them.

[xoviat]

If --log-level=TRACE is not working, then the solution is to find out why. Not ignore it.

[bwoodsend]

@dsaylikoglu That's not the unicode error. What was the traceback from that one?

It looks like your using full blown Anaconda (i.e. not MiniConda) which means that your environment will be huge because Anaconda installs hundreds of huge packages. That's why you keep getting recursion errors. The fix is to create a virtual environment containing PyInstaller and the packages you need. It's up to you whether you use venv or conda to do this.

[dsaylikoglu]

i tried with a conda env but didn't work

[bwoodsend]

but didn't work

Could you be a little more descriptive?

[dsaylikoglu]

I created a conda env inside the project's folder and tried to run the cmd there, but as I said, it failed.

[bwoodsend]

What commands did you use to create the environment, activate the environment, run PyInstaller, test your application? Which step failed and what was the full error message?

[Anonteam798]

Hello guys, I have the same issue with pyinstaller and I cant find any solution

[bwoodsend]

[sigh]. @Anonteam798 Can you please fill out the issue template so we know what your problem is.

[Anonteam798]

I can't convert my programm from ".py" to ".exe" with pyinstaller, it shows me a recursive error, and try to write in ".spec", then I TRY again to convert but when it finish, I can't run my programm ".exe" from the directory,

I have python 3.7, My programm is a GUI with TKINTER
What can I do to solve my problem? Please help me

[rokm]

but when it finish

If it finished, then you're not having recursion error anymore.

I can't run my programm ".exe" from the directory,

What's preventing you from doing that?

[Anonteam798]

Hi bro, I solve my problem, creating a virtual environment with ANACONDA , install the main packages, and finally it worked, but I'm confused because with pyinstaller I COMPILE one python file but my programm depends on another python file
What can I do?
