I generated a .whl file following this link:
https://dzone.com/articles/executable-package-pip-install
Now i am installing the package on my own machine to check if package is successfully installed. It installs successfully.
But the thing is when i import it, it gives, "ModuleNotFoundError" exception.
What i want to know is that how do i verify the .whl file is correctly generated and usable?
Please Help i am stuck here for 2 days.
Here's my Setup.py file
And here's my package directory structure:
Here's output of my build script:
Here's my stacktrace of import error:
You've declared TestFunc as a script (to be run from the command line), not a module. (I bet you haven't tried import TestFunc without packaging things into a wheel.)
If you're trying to build a wheel that will install an importable module, you'll want to rename TestFunc to TestFunc.py (like you'd do with any old Python module!) and then use
setup(
# ...
py_modules=["TestFunc"],
)
(and probably eventually packages=...) when your project grows, but that's beside the point)
.
If you're actually looking to have TestFunc being a script run from the command line, scripts is the right thing, but the script will have to be something your shell can understand – see the packaging guide here for the gist of it.

I installed python interpreter but i don't know how i can run the package.
I already tried to use windows cmd.
Ididn't used python before ,thanks a lot for helping me.
py-optim github
The github repository lacks a setup.py. If you want to install it, add the following code with the name setup.py to the top-level folder of the repository on your device. Then add one __init__.py file to the folder ..\PyOptim. The __init__.py can be totally empty. Try also to file an issue in the repo, stating that the setup.pyis missing.
from setuptools import setup
setup(name='pyoptim',
version='0.1',
description='optimizerTool',
url='https://github.com/schaul/py-optim',
author='None',
packages=['PyOptim',
'PyOptim.algorithms',
'PyOptim.benchmarks',
'PyOptim.core',
'PyOptim.external_libs'])
Afterwards, open a cmd in the top-level folder, and run
python setup.py install
This installs everything. You then can import everything.
Note: This is only a quick- setup.py. Please also add install-requeries and so on to install dependencies of the repo.
If you want the folders test and tools also to be installed, add an empty __init__.pyfile to these folders as well and add the names in the packages list in the setup.py.
EDIT: Use this fork of the repository were i added the missing files. Make sure you install python 2.x as this repo is not for 3.x.
I installed meshpy (using python 2.7) following the instructions here on my ubuntu 16.04 LTS and trying to run examples from here after browsing into the directory of meshpy. Part of the example that I'm trying to run is below:
from __future__ import division
from __future__ import absolute_import
import meshpy.triangle as triangle
but I keep getting error No module named meshpy._triangle
Does anyone have a hint of what I might be missing ?
Likely you have created file named meshpy within your python package, which leads to the module shadowing, renaming your file shall fix the problem.
See more by next links:
The name shadowing trap
Python: Problem with local modules shadowing global modules
After an entire day of labor I realized the python packages that I had were not correct and causing conflicts. To begin with here is the link to the installation documentation of meshpy which I followed Here is a pointwise summary of what I realized caused problem
Step 1 says download the file, unzip it using the command given in the doc, and browse to the directory 'MeshPy-XXXXX', where 'XXXXX' refers to the version.
The issue in this step is that a file called CMakeList.txt is missing in this directory and while configuring in step 2 the system complains about the missing file.
The solution is to download the git version instead of the direct download as mentioned in the second part of step1 or manually copy the file CMakeList.txt into the MeshPy-XXXXX directory. I chose the latter solution.
In step 2 asks us to browse to the directory and issue the command ./configure on the terminal. This didn't work for me. The directory contains a script called configure.py . Hence instead I issued python3.5 configure.py
If you issue python configure.py and python calling python2.7 then you should make sure python2.7 has matplotlib, numpy installed as meshpy depends on these packages
The last of step2 where you need to issue command python setup.py install is a tricky part where things went crazy for me. Firstly, I issued python setup.py but what I should have done is issuing python3.5 setup.py (or better creating an alias to python3.5 in bash).
When I pinned down the mistake, I started getting another error both with python2.7 and python3.5, last three lines of which looks like below :
bpl-subset/bpl_subset/boost/python/detail/wrap_python.hpp:50:23: fatal error: pyconfig.h: No such file or directory
compilation terminated.
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
When I looked up stackoverflow for possible similar errors, I came across this article and used the second solution in the post and installed python2.7-dev/python3.5-dev which solved the problem .
Go to the installation page and click on 'Download MeshPy' link. Click on 'Download Files'. Download the tar file. Unzip it. Then copy the 'meshpy' folder and paste it inside your python lib directory where other packages are stored. Hope it will solve the problem.
I'm trying to install PyDrive [a wrapper library of the google drive api for python] and pip is giving me this error. It did the same thing when trying to install things like matplotlib or mega.py [a mega.nz api for python].
Here's the error:
Anyone got a clue what's going on?

You could try renaming that pip.py to something else.
There is a library called pip somewhere on your system (and it may also be bundled within pip.exe). That is different from the "entry point" script that actually runs pip from the command line. When you run pip, it will try to import the library called pip. If there is a script called pip.py in the Scripts directory (representing the entry-point script, not the library), it may import that instead of the real library. If this is indeed the problem, renaming pip.py to something else will remove the name conflict and allow pip to properly import the library it needs.
I'm not sure how you wound up with pip.py in your Scripts directory in the first place. I don't think it should be there. My Python installation on Windows doesn't have it.
I have made a GUI application using python and PyQt5. I want to package this app but there doesn't seems to be a straight forward way to do this. Moreover what I have found answers to is to package a python module and not an application. I have read various articles and the official docs but still don't seem to have a proper answer to this, though there are several workarounds through which I could achieve the same, I just want to know what is the standard way.
This is my directory structure :
Moodly/
Moodly/
__init__.py
controller.py
logic.py
models.py
view.py
resoure.py
style.py
sounds/
notify.wav
message.wav
setup.py
MANIFEST.in
setup.cfg
run.py
moodly.png
Moodly.desktop
What do I want to achieve: The user is given with a tar file of Moodly. The user extracts it, runs the command
python setup.py install
in the terminal, the setup places all the files in the proper place and creates a Moodly.desktop file probably in usr/local/share/applications clicking on which user can run the app.
My way of achieving this:
setup.py
from setuptools import setup
setup(
name="Moodly",
version="1.0",
author="Akshay Agarwal",
author_email="agarwal.akshay.akshay8#gmail.com",
packages=["Moodly"],
include_package_data=True ,
url="http://github.com/AkshayAgarwal007/Moodly",
entry_points = {
'gui_scripts': [
'moodly = Moodly.controller:main',
],
},
# license="LICENSE.txt",
description="Student Intimation system",
# long_description=open("README.txt").read(),
# Dependent packages (distributions)
)
MANIFEST.in
include Moodly/sounds/notify.wav
include Moodly/sounds/message.wav
Now with no setup.cfg I run the command:
python setup.py install
This succesfully installs Moodly to /usr/lib/python-3.4/site-packages
alongwith the sounds directory.And now from the terminal when I type in moodly(as specified in entry points in setup.py) my GUI application launches successfully.
Now I just need the setup to create the Moodly.desktop alongwith moodly.png in usr/local/share/applications which I am trying to achieve through this:
setup.cfg
[install]
install_data=/usr/local/share/applications
Adding this to setup.py
data_files = [("Moodly", ["moodly.png","Moodly.desktop",])],
But this somehow seems to copy the files inside python-3.4/site-packages/Moodly rather than the specified destination but it used to work well with distutils
This guy also seems to have faced the same issue
Some other links I have used:
python-packaging
starting with distutils
So the way I am trying to do it , how much of it is correct and what is the standard way to do it. How can I possibly place that Moodly.desktop in the right place or what could be a better alternative way to do the entire process.
Moreover would using Pyinstaller be a better idea. Pyinstaller would package the app with PyQt5, requests and beautifulsoup4 (external modules that I have used) which I don't want. I want to use the install_requires option provided by setuptools and not unnecessary make the user download the modules which they already might have.
The .desktop file isn't supposed to be installed using Distutils. Distutils is only concerned with installing Python packages.
To install .desktop files, icons and other files incidental to distribution level packaging, you should look at build automation systems, such as CMake.
The first step in this process is to get CMake to build a Python project. You should take a look here for how to do that: https://bloerg.net/2012/11/10/cmake-and-distutils.html
Beyond that, installing .desktop files is easy. Assuming you've written a .desktop file and put it somewhere, installing it is a matter of doing:
install(PROGRAMS com.akshay.moodly.desktop DESTINATION ${XDG_APPS_INSTALL_DIR})
in your CMakeLists.txt file.
Note that you install the .desktop file to ${XDG_APPS_INSTALL_DIR} (that's a CMake variable), not a hardcoded path like /usr/local/share/applications or something. The user (and pretty much every automated distro package builder) will always install your package to a temporary path and then copy files over into their packages. Never assume that your app will live in /usr/bin or /usr/local/bin or whatever. The user could install things into /opt/Moodly or even $HOME/Moodly.
I have created a simple python module with SWIG (from C++). It is in the form of a .pyd file and a .py file.
I want to be able to give this module to my colleagues so they can install and use it.
I am aware that python modules are often installed using:
python setup.py install
Perhaps this is the functionality I want, so that my colleagues can run this module from anywhere without worrying about PATH etc.
I also would like to be able to send them an updated module from time to time, which will overwrite the older version when they install it.
How do I go about this?
As far as I can understand this question, you want a setup.py file to install your module
go through the steps given below :
create a directory on Desktop (name it "source" for example)
put your .py and .pyc files in it.
go to Desktop and create setup.py file and enter the following code
as
from distutils.core import setup
setup(name='Some_name',
version='1.0',
author='Author_name',
author_email='abc#xyz.com',
packages=['source']
)
4. To use it in any program.
import module_name from source
hope this helps !
