I need to use the sksparse.chomod package however my pycharm does not let me install it as it can't seem to find it.
I found the sksparse package on github and downloaded it but I do not know how to add a package downloaded from the internet into a conda environment. So, my first question would be can you download a package from github and add it to your conda environment, and how do you do this?
As I did not know how to do the above I instead saved the package within my project and thought I could simply import sksparse.cholmod. However, the line in my code that says import sksparse.cholmod as sks has no errors with it, so I assumed that meant this was ok, but when I try to run my file I get this error:
import sksparse.cholmod as sks
ModuleNotFoundError: No module named 'sksparse.cholmod'
If I have downloaded the package into my project why can't it be found, yet there are no errors when importing?
The cholmod file is a pyx file which I've been told should not be a problem.
Please could anyone help, I am reasonably new to python and I am looking for a straight forward solution that won't be time consuming.
It was an issue with windows, I was able to fix this using the instructions on this link

We must follow these steps precisely:
(This was tested with a Anaconda 3 installation and Python 3.7)
Install these requirements in order:
'''
conda install -c conda-forge numpy - tested with v1.19.1
conda install -c anaconda scipy - tested with v1.5.0
conda install -c conda-forge cython - tested with v0.29.21
conda install -c conda-forge suitesparse - tested with v5.4.0
'''
Download Microsoft Build Tools for C++ from https://visualstudio.microsoft.com/de/visual-cpp-build-tools/ (tested with 2019, should work with 2015 or newer)
Install Visual Studio Build Tools
Choose Workloads
Check "C++ Buildtools"
Keep standard settings
Run ''' pip install git+https://github.com/EmJay276/scikit-sparse '''
Test ''' from sksparse.cholmod import cholesky '''
Use all the versions stated for numpy etc, however with scipy I installed the latest version and it worked fine.
I installed Python 2.7, Pycharm 2017.3 and in pycharm in
settings > project interpreter > add package
I searched for numpy and installed the package but I get this error:
Error occured:
_configtest.c(7): error C2143: syntax error: missing ';' before 'volatile'
Proposed solution:
Try to run this command from the system terminal.
Make sure that you use the correct version of 'pip' installed for your Python interpreter located at
'C:\Users\Admin\PycharmProjects\second\venv\Scripts\python.exe'.
I tried by reinstalling everything but it didn't work.
I suppose that you are trying to install numpy on windows.
On windows, install this package could be quite complicated, so my suggestion is to use an unofficial installer for Numpy.
Here you can find the link with all unofficial installers, please search and open the Numpy link in the list.
Keep in mind to choose the right version, in this way:
cp = python version (i.e. cp27 = Pythonv2.7)
win_amd64 = x86_64 or win32 = windows 32 bit
Download it and then install it with the following command
pip install --user <numpy.whl>
for example, the following command install numpy v.1.13.3, for Python2.7 and for windowns 32:
pip install --user numpy‑1.13.3+mkl‑cp27‑cp27m‑win32.whl
Solved on Pycharm Pro and Comunity Edition
This is about near deprecation python 2.7, and dependencies requires older versions.
***File > Settings > project interpreter > Double Click to pip package >
Check Specify version to 9.0.1 (downgrade version to older). Click to install package.
***File > Settings > project interpreter > Add package (+) > Search and select matplotlib > Check Specify version to 1.5.3 (Downgrade to older). Click install package.

I am a CS beginner taking udemy python course and trying to install pip in order to use matplotlib, pandas and so on in pylab.
I use IDLE 3.4.2 and latest version Pycharm
Tried
1. "pip installed pylab"(version not satisfies the requirement pylab,no matching distribution found for pylab);
2.same result with sudo before the first one;
3.sudo easy_install matplotlib（succeeded in terminal, but still no matplotlib module in shell) ;
4.brew install python 3(succeeded , but still no matplotlib module in shell, and every command looks like still for 2.7)
5.Anaconda Package based on preinstalling Macports (same result as 3)
6.On cloud9.io, still can't import matplotlib
Then tried to uninstall both 2 and 3 python then install
7.brew rm -rf/Library/Frameworks/Python.framework/Versions/2.7
(error:no keg argument)
Downloaded Xcode but "block compressed payload operation failed"

Answer in detailed direction will be appreciated as I am just a beginner having tons of stuff to learn from you.
Really frustrated by now.
Just installed python, and am running into this error:
ImportError: No module named 'semanticnet'
here are my imports:
import semanticnet as sn
import sys
I've tried the solution on this site that suggests adding:
sys.path.append('C:\Python34')
after the 'import sys', but no luck.
Does anyone know what could be causing this issue?
Here is my full code: https://ideone.com/UHRI4S , running windows 10
You need to install that library, if you're on windows which it seems because of your "C://" first install setuptools.
https://pypi.python.org/pypi/setuptools
Using Windows 8 (which includes PowerShell 3) or earlier versions of Windows with PowerShell 3 installed, it’s possible to install with one simple Powershell command. Start up Powershell and paste this command:
(Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -
You must start the Powershell with Administrative privileges or you may choose to install a user-local installation:
(Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user
If you have Python 3.3 or later, you can use the py command to install to different Python versions. For example, to install to Python 3.3 if you have Python 2.7 installed:
(Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | py -3 -
Once installed run as follows:
easy_install semanticnet
I think you don't have the module installed..
try pip install semanticnet on the Prompt Command first(I believe that you installed pip when you installed python), then when the installation is complete, just run python and try some ´import semanticnet` on the python command line...
I am running Anaconda Python 2.7 on a Win7 x64 machine and used
pip install PyOpenGL PyOpenGL_accelerate
at the Anaconda command line to install PyOpenGL.
I have some code (not my own I must confess) that makes use of glutInit
import sys
import math
import numpy
import OpenGL
from OpenGL.GL import *
from OpenGL.GLUT import *
import Image
import linkage
# ... a whole load of definitions etc ...
glutInit(sys.argv)
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB)
glutInitWindowSize(600, 600)
glutCreateWindow('linkage')
init()
initWindow()
glutIdleFunc(idle)
glutMainLoop()
I run by entering the following at the command line:
python main.py peaucellier.txt
But then get the following error (line 371 is the glutInt(sys.argv) line above)
File "C:/Users/Owner/Documents/Python Scripts/linkage/main.py", line 371, in <module>
glutInit(sys.argv)

self.__name__, self.__name__,
NullFunctionError: Attempt to call an undefined function glutInit, check for bool(glutInit) before calling
I have looked at similar errors posted in this forum but none of the proposed fixes are working which is why I'm asking, what's wrong here?
Is the installation at fault? Are the imports correct?
EDIT: After trying many many fixes for the official release I am now using an unofficial release that works perfectly from Unofficial Windows Binaries for Python Extension Packages
According to the link below the problem was with the glut installation rather than pip install. It seems glut files are not part of PyOpenGL or PyOpenGL_accelerate package. You have to download them seperately.
https://stackoverflow.com/a/39181193/7030177
Windows user can use the link below to download glut as mentioned in the given link.
ftp://ftp.sgi.com/opengl/glut/glut3.html.old#windows
Linux Users can just install glut using the following command:
sudo apt-get install freeglut3-dev
Hope this helps :)
After looking around for a solution to a similar problem I ran across this google group that answers the question: https://groups.google.com/forum/#!topic/glumpy-users/aC1NjEHXtEE
There is a problem with OpenGL.GLUT when downloaded as pip from the official source. Uninstall OpenGL using pip, then download OpenGL from http://www.lfd.uci.edu/~gohlke/pythonlibs/
For people on Linux with this error after installing via easy_install PyOpenGL or pip install PyOpenGL.
-> Install the distribution package as: sudo apt-get install python-opengl - this works for me.
If installing PyOpenGL from easy_install, pip or conda, make sure that you have already installed a GLUT implementation, such as FreeGLUT (prebuilt Windows binaries).
For FreeGLUT, copy the distributed files to a location on your hard drive and then add the path to the bin directory (which contains the GLUT DLLs) to your PATH environment variable. Then PyOpenGL should work as expected.
It is mainly because you're running 64-bit windows put pip is installing 32-bit version of PyOpenGL.
To fix this, follow these steps:
Uninstall existing PyOpenGL, Run pip uninstall PyOpenGL PyOpenGL_accelerate
Download the 64-bit builds of PyOpenGL and PyOpenGL accelerate from here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopengl
How to choose which one to download? Well, first you need to check your python version. Run python --version to determine.
Then according to your version download the whl files for PyOpenGL and PyOpenGL accelerate. For example, if you have Python 3.8, download these 2 files:
PyOpenGL‑3.1.5‑cp38‑cp38‑win_amd64.whl
PyOpenGL_accelerate‑3.1.5‑cp38‑cp38‑win_amd64.whl
Similarly, if you run Python 3.9, download these instead:
PyOpenGL‑3.1.5‑cp39‑cp39‑win_amd64.whl
PyOpenGL_accelerate‑3.1.5‑cp39‑cp39‑win_amd64.whl
Note: Must download amd64 ones, after all, you're running 64-bit windows.
Now go to the folder where you downloaded the files and run powershell/cmd with administrator there.
Use pip to force install those files. For example:
pip install PyOpenGL-3.1.5-cp38-cp38-win_amd64.whl --force-reinstall
pip install PyOpenGL_accelerate-3.1.5-cp38-cp38-win_amd64.whl --force-reinstall
Note: Install PyOpenGL first and then PyOpenGL_accelerate
If the installation succeeds, you may be able now to run.
Some facts to make sure:
*All platforms must be of the same bit version.
*System type, python, OpenGL needs to be of the same bit version. In my case it was x64 bit
*It is necessary to restart your desktop if you reinstall any one of them (Python, OpenGL)
*It is recommended to keep your pip version at 20.3, I downgraded it from 21.1.3
I got the same error and a solved installing required files from here.
Download these files:
PyOpenGL-3.1.1-cp27-cp27m-win32.whl (download if your computer 32 bits )
PyOpenGL-3.1.1-cp27-cp27m-win_amd64.whl (download if your computer 64 bits )
PyOpenGL_accelerate-3.1.1-cp27-cp27m-win32.whl (download if your computer 32 bits )
PyOpenGL_accelerate-3.1.1-cp27-cp27m-win_amd64.whl (download if your computer 64 bits )
install these .whl files for 64 bits:
pip install PyOpenGL-3.1.1-cp27-cp27m-win_amd64.whl
pip install PyOpenGL_accelerate-3.1.1-cp27-cp27m-win_amd64.whl
install these .whl files for 32 bits:
pip install PyOpenGL-3.1.1-cp27-cp27m-win32.whl
pip install PyOpenGL_accelerate-3.1.1-cp27-cp27m-win32.whl
for python 2.7, PyopenGL needs vc++ 9 compiler, download and install it.
then:
python -m pip install --upgrade pip
pip install image
pip install numpy
pip install PyOpenGL PyOpenGL_accelerate
I downloaded freeglut
unzipped it and added bin directory to the path
when calling: glutCreateWindow("sometitle")
changed to glutCreateWindow(b'sometitle')
and got it run on windows 7
My case is different, Python 3.6 and windows 10. However exactly same error message. Tried all above solutions, no success.
Downloaded WHL file right to my computer and version of python from HERE
Then pip installs filename.Whl, no more issue!
The answer was from a Chinese website: Answer Link
Yes, this happened to me on Windows 10 running python 2.713 anaconda 4 64 bit. I had used conda to install pyopengl but received the same error as above. So I downloaded freeglut from transmissionzero and just copied the freeglut.dll (64 bit for me) to the same directory as my source file (it just needs to be in the dll searchpath) and all was good.
I know it is a little late. I also encountered this problem with python 2.7 (32 bits) in windows. I tried the method mentioned by user2723240 but still failed. Finally, I solved this problem by copying glue32.dll to System32 in C drive and copy glue32.dll into my source file directory. It works well now.
On linux, the pyopengl module attempts to use ctypes module to load the glut library as simply 'glut'. According to ctypes documentation the loadLibrary routine must be given the complete filename. Therefore, I made a symbolic link to libglut.so and named it 'glut' and everything just worked.
The following command should work for Anaconda users:
conda install -c conda-forge freeglut
https://anaconda.org/conda-forge/freeglut
On windows, although PyOpenGL says it installs freeglut by default, it does not.
To patch it, you must download or compile freeglut (other answers here contain the appropriate links) and place it in a new site-packages/OpenGL/DLLS folder inside to your existing OpenGL site-packages installation.
Once there, the freeglut.dll needs to have the bits and the MSVC version appended to the filename. OpenGL/platform/win32.py has the details on exactly how it's detected.
To make it clearer the filename needs to be the one printed from the following script:
import sys
import platform
if sys.hexversion < 0x2070000:
vc = 'vc7'
elif sys.hexversion >= 0x3050000:
vc = 'vc14'
elif sys.hexversion >= 0x3030000:
vc = 'vc10'
else:
vc = 'vc9'
size = platform.architecture()[0].strip('bits')
print(f'freeglut{size}.{vc}.dll')
Step 1
Install python in your system windows 10/11 preferred. for python 3.8.0 : https://www.python.org/ftp/python/3.8.0/python-3.8.0-amd64.exe
If you have already installed then check for your python version
Open terminal and type "python --version"
it will display your python version. for example I have installed python 3.8.0.
Step 2
Next open terminal and run the below command
python -m pip install --upgrade pip==20.3
sometimes you have higher version of pip installed but its okay to downgrade back to version 20.3
Step 3
now for installing OpenGL go to this site : https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopengl
and download
PyOpenGL‑3.1.6‑cp38‑cp38‑win_amd64.whl (for 64bit windows) or
PyOpenGL‑3.1.6‑cp38‑cp38‑win32.whl (for 32 bit)
and
PyOpenGL_accelerate‑3.1.6‑cp38‑cp38‑win_amd64.whl (for windows 64bit) or
PyOpenGL_accelerate‑3.1.6‑cp38‑cp38‑win32.whl (for windows 32bit)
Note : I have in installed python 3.8.0. so I downloaded PyOpenGL having cp38 word in it. If you have installed python 3.9 or other version download the above mentioned file having name cp39,cp10 etc.
after downloading both files according to your python version. put it a folder.
Step 4
then open terminal from that folder. Windows 10 lets you launch Command Prompt in a folder through the File Explorer's address bar. Type “cmd” in the address bar and then hit Enter
after opening terminal enter the below command
pip install PyOpenGL-3.1.6-cp38-cp38-win_amd64.whl --force-reinstall
then after installing it run the below command
pip install PyOpenGL_accelerate-3.1.6-cp38-cp38-win_amd64.whl --force-reinstall
Note : Don't forget to change the file name ( e.g. : PyOpenGL-3.1.6-cp38-cp38-win_amd64.whl) to the file name that you have downloaded.
