Compiling .pyx files was working fine but suddenly it started raising error when I type:
python setup.py build_ext --inplace
I get the error:

I tried running it on a simple .pyx file helloworld:
def say_hello_to(name):
print "Hello %s!" %name
with the setup.py:
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
setup(
name = 'Hello world app',
cmdclass = {'build_ext': build_ext},
ext_modules = [Extension("hello", ["hello.pyx"])]
)
It already worked several times, something has changed but as I Googled and searched the issue I couldn't find any information. I'm using Python 2.7 64 bits, latest version of Cython and to compile the file I use Windows SDK C/C++ compiler and prepare the environment by running:
C:\Program Files\Microsoft SDKs\Windows\v7.0>set DISTUTILS_USE_SDK=1
C:\Program Files\Microsoft SDKs\Windows\v7.0>setenv /x64 /release
Any ideas of what might have happened? Tnx in advance!
I got the same error when running from a python script:
os.system("python setup.py build_ext --inplace")
while
python setup.py build_ext --inplace
worked from command promt.
The reason was that the name of my test package was "cython"... stupid me
I have had the same error.
Worked on it for one whole day until I have realized that I have followed some blog entry to create a cython.py file in my directory holding some information how to compile.
I do not recall where I found this but by removing this file everything works fine
I'm not sure this helps, but when I got this error I deleted all .pyc files and ran the script again via IDLE (opened in IDLE and clicked F5) and then it worked just fine.

I am trying to create an executable for a script I have already written. It will be used by a coworker who doesn't have python on their machine, so I want to create an executable to make their life easier. I'm currently just trying to get py2exe to work and create an executable for a simple script that simply prints hello world and the constant e from the math module (just to get an idea for how py2exe works).
My setup script is as follows:
from distutils.core import setup
import py2exe
import math
setup(
console=[{'script':'hello.py'}],
options={
'py2exe':{
'packages' : ['math'],
'bundle_files':1
},
},
version='1.0.0'
)
where hello.py is simply:
import math
print('hello world!')
print(f'Here is e: {math.exp(1)}')
The error comes from this stack after I call "python setup.py py2exe" in cmd

To covert a .py file to .exe you need to install auto-py-to-exe
Windows
pip install auto-py-to-exe
After it is installed, open cmd then type
auto-py-to-exe
Then specify the path of the script and the location where you want to save the .exe file.
I have created a python application that I now want to make into a standalone application. I am using cx_freeze from a virtualenv, which has worked before on my machine with scripts that have less dependencies.
I am currently running into an issue where cx_freeze errors when it tries to copy dylib files that are named the same to the build folder.
I am running the command:
python3 setup.py build
My setup.py file looks like:
from cx_Freeze import setup, Executable
build_options = {'packages': ["PySimpleGUI", "matplotlib", "pandas", "descartes", "geopandas", "cities_coordinates"],
#'excludes': ["PIL", "pyproj", "setuptools"],
"zip_exclude_packages": [],}
import sys
base = 'Win32GUI' if sys.platform=='win32' else None
executables = [
Executable('main.py', base=base, targetName = 'data_visualizer')
]
setup(name='data_visualizer',
version = '0.1',
description = 'Data visualization tool',
options = {'build_exe': build_options},
executables = executables)
This is the error I am getting:

(This may be caused by including modules in the zip file that rely on binary libraries with the same name.)
If I exclude libraries that introduce a dylib that conflicts with another (see commented out excludes build option in the setup.py) then the command will run successfully, but my built application will fail because of missing dependencies.
Does anyone know of a way to get around this issue?
Some other info if it matters ->
Operating System: Mac OS Big Sur
Python Version: 3.7.8
cx_freeze version: 6.2
This same name error appears to have been reported in this cx_Freeze issue, introduced by this pull request that raises an error when copying a second file onto the path of another.
A workaround was merged to print a warning and simply use the first copy of the file rather than raising an error. As it doesn't appear to have been released yet (as of 2021-03-09, v6.5.3), I installed cx_Freeze from Git (after cloning and entering the repo, I installed it by pip install -e .), ran cxfreeze, and saw warnings such as this:
*** WARNING ***

Using only source 1.
where the conflicting file was simply skipped, allowing the build to proceed.
I want to build_ext a ".pyd" file but it didn't work.

Anyone having the same issue?
I have followed the instructions on: https://github.com/pybrain/pybrain/wiki/installation.
what am I missing?
The Pybrain can be setup by pip install pybrain directly.
The FNN in pybrain have a bit problem of convergence and performance. As substitution, there are lots of advices on Python for AI, such as FANN (An example) and scikit-learn (for lots of ML method but not contains FNN directly).
Try not to use pip. I always prefer getting the entire folder from PyPI or github (if available) and then doing the simple python setup.py install.
Also, whenever you do some work with the packages which are under active development (or not very commonly use), please read their documentation.
If you see the documentation : Here. You will see that they use Python 2.x.
And you are clearly using Python 3.x.
Get Python 2.x and download the folder from github. Unzip it and install.
Hope it helps.
Cheers.
Try following queries:
pip install numpy
pip install scipy
pip install pybrain
OR:
download ez_setup.py and run it:
python ez_setup.py
OR:
use easy_install:
easy_install pybrain
I am using cx_Freeze with Python 3.4.1 and I am trying to create an application from one of my Python programs. Unfortunately, I get this error after running the setup.py build:

Any help would be appreciated.
Reposting as an answer:
Relative path names are found relative to where you run from, not where the the setup.py script is. Use cd in the terminal to change to the directory where setup.py is, and then run python setup.py build.
If that's not practical for some reason, you could use os.chdir() inside the setup.py script.
