I just installed kivy on python 3.5.0. However, every time I try to import kivy; it shows the error "No module named Kivy".
I am very new to all this so step by step instructions would be helpful.
Many operating systems come with python 2.7 and 3.5 already installed. I know you said you have 3.5, but check this anyway with python2 -V. In the comments,you said that you have been importing kivy correctly into your files. It may be that you are accidentally running your python3 app with python2.
Kivy for python2 is not the same as kivy for python3. If you want to be sure that you're running with the python version you want, run your app with python3 filename.py.
If all this is said and done, and you still don't find out what's wrong, you either installed kivy for python2 somehow or it's searching for kivy in the wrong place.

As you can see I have imported the modules correctly using pip install. I googled a bit why the module was not imported and I realized I have to add it to PATH. I did that too but now there is a new error something about a syntax error
File "pygame/__init__.py",
self.reason = f"{exc_type.__name__}: {self.info}"
Is this because my chrome book can not run Pygame or is the problem something else?
Picture of my terminal with the error:
you need to run python3. to start python 3. Just running python starts python 2.7.
you have your installed packages in python 3.9 version while your python environment is 2.7, look for python3 executable and try with that version
I have just started learn how to use python so please forgive me if I come off as a beginner. The programming tool that I want to run requires PyGTK 2.7 or higher, and from what I figure the only way to run the pygtk module is to install msys2. I followed all of the steps up to step 7 in the link attached https://pygobject.readthedocs.io/en/latest/getting_started.html 1, and I wasn't able to run the hello.py script they attached, despite successfully installing msys2 and updating the package database and core system packages. I keep getting the same error message when I try to run the code - "ModuleNotFoundError: No module named 'gi'". Afterwards, I tried running the programming tool anyway and I received a similar message "ModuleNotFoundError: No module named 'pygtk'".
PyGTK is deprecated and no longer being maintained. It hasn't been updated since 2011.
PyGObject is what replaced it. You won't be able to install PyGTK using the instructions you referenced.
You can install PyGTK still using:
pacman -S mingw-w64-x86_64-python2-pygtk
I'm having a problem with importing modules in python.
When I run my program in the command line it works perfectly fine.
However, when I try to run the same program in the python shell I am prompted with the following error:
ModuleNotFoundError: No module named 'matplotlib'
I already successfully installed matplotlib using 'python -m pip install matplotlib'.
I've read this can happen when you have two different versions of python installed; however, I don't.
I've uninstalled and reinstalled python and I still am having the same issue. I've also uninstalled and reinstalled matplotlib using pip.
I believe my problem is the module paths that python uses to search for imported modules are different between the two.
When I use the 'print(sys.path)' command in the python shell and the command line I get two different outputs.
Any help would be greatly appreciated!!!
The file different system paths between the python shell and the command line
You have two versions of python. I would recommend you to remove all pythons you have and go for anaconda https://www.anaconda.com/distribution/. It will fix your path problems and allow you to create environments with different versions of python. This is the least painful way also for future :) good luck.
I suppose, you have both of the Python versions installed on the same computer.
If that is so, then my answer would be to go inside both Python script folders and install matplotlib on both of them.
I have also faced that issue. My path includes pip of Python 3.7.1 and whenevwer I try to import modules on Python 3.4. It throws an error!
Maybe, you could add both of the Pythons to the path.
I encountered this same problem – python -c "import sklearn" would work just fine, but import sklearn inside a Python program failed. Both my one-liner and program was using the same Python version (version 3.8.10).
I eventually got the program to work by replacing the shebang line (originally #!/usr/bin/python) with #!/bin/env python.
I don't know why this worked exactly (sorry). Presumably some path got reset, and the module loaded from a different location, but it might help someone so I'm posting it here nontheless. (If you know more, feel free to edit this answer.)
I have built a GUI using PyQt5 and wanted to distribute it to other computers without Python installed by packageing it with pynsist. Unfortunately, when launching the shortcuts produced by the installer, the GUI does not open as expected and Python keeps crashing (even if Python is instlalled).
The console shows the following error upon crashing:
ModuleNotFoundError: No module named 'sip'.
This is due to from PyQt5.QtCore import *.
Unfortunately, when launching the .launch.py script on a computer with Python installed, everything works fine. I suppose this is because it then targets the installed version instead of the version included in the build of the GUI.
However, the shortcuts do not work, no matter if Python is installed, giving me the above error.
Any ideas how to fix this problem and make the shortcuts work on computers that do not have Python installed?
Thank you in advance!
When I first encountered this problem I simply added sip.pyd to my project-folder. You can find it under:
x:/path-to-python/Lib/site-packages/sip.pyd
but what realy solved my problem was using pyinstaller.
It automatically detects most dependencies and most of the time runs without complicated configurations.
pip install pyinstaller
pyinstaller main.py
# done
Sip is a separate package which PyQt5 requires. You can include it with your application by listing it in pypi_wheels=, as in the PyQt5 example:
[Include]
packages=listapp
pypi_wheels= PyQt5==5.6
sip==4.18
If you're using the latest version of PyQt5 (5.10.1), then the latest version of sip (4.19.8) should work with it.
I'm currently doing the exercise in "Learn python the hard way".
In this exercise i have to install the lpthw.web frame work.
Having installed pip in windows, i open my terminal and hit
pip install lpthw.web
Everything then ends succesfully.
But when i browse C:\Python27\Lib\site-packages\lpthw.web-1.1-py2.7.egg-info and check the installed-files text i can't see the web.py.
Consequently when i try to import it in a simple script i get ImportError.
I don't have python 3 installed as book suggested for possible cause, so i don't know how to work around it.
Any suggestion?
I checked my path
import sys
sys.path
and saw that every single line was using the panda3d path.
As i was not really using it, unistalling it fixed my problem.
For me it was python version control on raspberry pi
(linux) 2.7 is default and does not work.
follow:
https://learn.sparkfun.com/tutorials/python-programming-tutorial-getting-started-with-the-raspberry-pi/configure-your-pi
have other errors now but the import web loads in python.
cheers!
