pyinstaller creating EXE RuntimeError: maximum recursion depth exceeded while calling a Python object

Question

I am running WinPython 3.4.4.3 with pyinstaller 3.2 (obtained via pip install pyinstaller).

Now I've got some really simple Qt4 code that I want to convert to EXE and I've run into problem that I cannot solve.

The Code:

import sys
import math
from PyQt4 import QtGui, QtCore 
import SMui
import numpy as np
from scipy.interpolate import InterpolatedUnivariateSpline

class SomeCalculation(QtGui.QMainWindow, SMui.Ui_MainWindow):
    def __init__(self):
        super(self.__class__, self).__init__()
        self.setupUi(self)
        self.setWindowTitle('Some Calculation')
        self.calculate.clicked.connect(self.some_math)

    def some_math(self):
        a_diameter=self.a_diameter.value()
        b_diameter=self.b_diameter.value()
        complement=self.complement.value()
        angle=self.angle.value()
        preload=self.preload.value()

### ONLY MATH HAPPENS HERE also defining X and Y ####

        interpolator = InterpolatedUnivariateSpline(X, Y)

### MORE MATH HAPPENS HERE ####

        self.axial.setText(str(axial))
        self.radial.setText(str(radial))

def main():
    app = QtGui.QApplication(sys.argv)
    window=SomeCalculation()
    window.show()
    app.exec_()

if __name__=='__main__':
    main()

I try to run pyinstaller file_name.py and I'm getting:

RuntimeError: maximum recursion depth exceeded while calling a Python object

Now if there's a few things that I have found out that also affect the issue:

1) If I comment out this line: from scipy.interpolate import InterpolatedUnivariateSpline

2) Creating EXE file from another different script that uses Scipy.Interpolate (RBS, but still) - works like a charm.

3) If I try to convert it to EXE using WinPython 3.5.1.1 + pyinstaller obtained the same way, and it's the same 3.2 version of it - it generates my exe file no problems.

I want to understand what's causing the error in the original case and I cannot find any answer on google unfortunately, most of the fixes I could find were related with matplotlib and not interpolation though.

Solution 1

This worked for me

1. Run pyinstaller and stop it to generate the spec file :

   pyinstaller filename.py
   

   A file with .spec as extension should be generated

2. Now add the following lines to the beginning of the spec file :

   import sys
   sys.setrecursionlimit(5000)
   

3. Now run the spec file using :

   pyinstaller filename.spec
   

Solution 2

Mustafa did guide me to the right direction, you have to increase the recursion limit. But the code has to be put to the beginning of the spec file and not in your python code:

# -*- mode: python -*-
import sys
sys.setrecursionlimit(5000)

Create the spec file with pyi-makespec first, edit it and then build by passing the spec file to the pyinstaller command. See the pyinstaller manual for more information about using spec files.

Please make sure to use pyinstaller 3.2.0, with 3.2.1 you will get ImportError: cannot import name 'is_module_satisfies' (see the issue on GitHub)

Solution 3

i'd try to increase recursion depth limit. Insert at the beginning of your file:

import sys
sys.setrecursionlimit(5000)

Solution 4

Even until March 2020, this issue has not been solved yet. As per some people's explanation, I increased setrecursionlimit in .spec file and tried to build it, but it did not work.

Through googling, I found out that this issue is caused by conflict of latest version of openpyxl and pyinstaller. Older version of openpyxl, such as 2.3.5 version, does not cause this issue.

As such, solution for this issue is as follows.

pip uninstall openpyxl
pip install openpyxl==2.3.5

Solution 5

Sometimes even the limit 5000 is not enough. It helped me to set limit to 20000. (in file 'filename.spec')

import sys
sys.setrecursionlimit(20000)

Did that. Doesn't help.

This seems to help for me, any idea why? Do you have a pointer?

[Anatoly Alekseev]

Wondering why creators of pyinstaller do not give recursionlimit as a commnad-line option. Or at lease mention the problem in the FAQ somewhere.

When I try to run a script from outside the package containing module, it errors out but if I call the script within the package it succeeds. Any idea ?

[Naazneen Jatu]

Thank you. Nothing on the internet worked for me except this!

[Pedram]

For me, it worked, but couldn't get any use of the EXE file. It runs but it will close afterward.

[Saleh Hosseini]

@Pedram open a terminal and run it from there

I am getting that error all of a sudden. And I always used a specfile.
