I've installed the latest python version 3.9.7 on my ubuntu 20.04 machine. I'm attempting to run some code that requires the Talos package, however I've attempted several times to install Talos using pip3. It does much of the work downloading and installing stuff, until it gets to something called "building wheel for scipy", and then after a lot of work, all I get is error messages. My first question is, is it possible that there is no version of Talos for 3.9.7, or that 3.9.7 is too advanced? If it should integrate Talos, how can I diagnose the problem so I can get it installed? Thx. J
This could be because the wrong version of Cython is being picked up. I have experienced this being the cause of scipy build errors in the past. I would try a pip3 install --upgrade cython first.
I'm trying to use Django and displaying images from a Sql db, following this LinkedIn Learning tutorial.
In the process of running manage.py to run my django development server, I face an issue where I have to have pillow installed.
This process has so far proven tedious and here are the things I've tried:
Ran the "simple" python -m pip Pillow, python -m pip Pillow --upgrade in the PyCharm terminal, then get:
a required dependency when compiling Pillow from source.
Please see the install instructions at:
https://pillow.readthedocs.io/en/latest/installation.html
(Pycharm Ultimate, which I have): Running the WSL environment as provided in the release notes. This should to work as I have the required pre-reqs installed in WSL. However, my computer runs the dreaded "skeletons" process for quite a long time, and I don't see it ending anytime soon.
Attempting to install from the PyCharm GUI also fails in the same way as 1.
Attempting to install the following binaries from https://www.lfd.uci.edu/~gohlke/pythonlibs/#pillow which is referenced in some other answers for this topic gives me this error when installing via pip install <wheel name here>:
Pillow-7.0.0-cp38-cp38-win_amd64.whl is not a supported wheel on this platform.
**pip3 doesn't work either. Mentioning although in my PyCharm virtualenv they both point to the same python interpreter. At first glance...
My main ask is - has anyone been able to install pillow 7.0.0 on Windows 10, for a PyCharm virtualenv? And, if so, how have you done it? So I can get back to learning! Thank you in advance!
EDIT: Updated steps taken in (1). Sorry about that
Did brew install ffmpeg, installs some packages and gives this error :
Error: python is already installed from !
Please brew uninstall python first."
I have python3.6.5 installed via brew, for using Tensorflow etc. No other python version is installed via brew right now. Why is this error coming up? What version does FFmpeg need?
Earlier I actually uninstalled python and that broke my system in many frustrating ways. I had to delete everything and start over. What is a safer way to get this working?
So I was looking around at different things to do on Python, like code for flashing text or a timer, but when I copied them into my window, there were constant syntax errors. Now, maybe you're not meant to copy them straight in, but one error I got was 'no module named wx'. I learned that I could get that module by installing wxPython. Problem is, I've tried all 4 options and none of them have worked for me. Which one do I download and how do I set it up using Windows?
Thanks
It's on PyPI. As of wxPython 4, Python 3 is supported.
Unfortunately, PyPI has a package called wx that is stuck at version 3.0.3; be sure to install the package named wxpython instead.
pip install wxpython
Please note that pip will automatically build wxWidgets for you, but it will not install wxWidgets system dependencies such as GTK and OpenGLu. If the above command exits with an error, look above for a message like this:
checking for <something>... not found
checking for <something>... no
configure: error: <prereq> libraries not available
Error running configure
ERROR: failed building widgets
This should give you information about at least one of the packages your system is missing.
The "official" list of prerequisites from the wxWidgets source is:
dpkg-dev
build-essential
libjpeg-dev
libtiff-dev
libsdl1.2-dev
libgstreamer-plugins-base0.10-dev # or 1.0 if available
libnotify-dev
freeglut3
freeglut3-dev
libsm-dev
libgtk-3-dev
libwebkitgtk-3.0-dev # or libwebkit2gtk-4.0-dev if available
libxtst-dev
The actual package names provided by your package manager may not match these exactly, and to be honest, I don't really know the best way to query a package manager to determine what packages provide the libraries you need.
3 steps to install wx-widgets and pygame in python IDLE
Install python 3xxx in your system opting (Add 3xxx to your path).
open python CLI to see whether python is working or not.
then open command prompt (CMD).
type PIP to see whether pip is installed or not.
enter command : pip install wheel
enter command : pip install pygame
To install wxpython
enter command : pip install -U wxPython
Thats all !!
As per home page instruction:
Make sure you have at least version 6.0.8 of pip and 12.0.5 for setuptools.
Install requirements for Linux as outlined in the readme.rst at:
https://github.com/wxWidgets/Phoenix/blob/master/README.rst
Install wxPython-Phoenix (Linux):
sudo pip install --upgrade --trusted-host wxpython.org --pre -f http://wxpython.org/Phoenix/snapshot-builds/ wxPython_Phoenix
Install wxPython-Phoenix (Windows, use the appropriate script folder):
C:\python27\scripts\pip.exe install --upgrade --trusted-host wxpython.org --pre -f http://wxpython.org/Phoenix/snapshot-builds/ wxPython_Phoenix
I installed wxPython as part of the PsychoPy experiment builder dependencies, and had considerable trouble getting it to install properly as well initially. But this was what worked for me at the end. I use Ubuntu 16.04, python 3.5, pip3 19.0.3
pip3 install -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-16.04 wxPython --user
If you use Conda then you may easily setup the environment with wx by one line:
$ conda create -n wxenv python=3 wxPython
Solving environment: done
## Package Plan ##
environment location: /home/user/.conda/envs/wxenv
added / updated specs:
- python=3
- wxpython
The following packages will be downloaded:
package | build
---------------------------|-----------------
[...]
Proceed ([y]/n)?
You need to ensure the versions of your wxPython download matches your installed python language library.
The current downloads wxPython downloads doesn't show any libraries built against python 3. I Believe the python 3 porting project is still ongoing.
If you are not sure of what you are doing I would stick with the 32bit version on windows as there are some Python libraries (ie IIRC, MySQLdb) which don't work with 64 bit python.
So you would then need to download python2.7 for windows x86 and "wxPython3.0-win32-py27 32-bit Python 2.7"
To install wxPython GUI library correctly go to the following page (https://wxpython.org/Phoenix/snapshot-builds/), which contains snapshots builds of wxPython library (Phoenix version) depending on your os and version of Python you want to work.
Then when you downloaded the proper package for your system and python version, simply install it by using pip. In my case I've choosen that one (wxPython_Phoenix-3.0.3.dev2811+ecc4797-cp36-cp36m-win_amd64.whl):
pip install wxPython_Phoenix-3.0.3.dev2811+ecc4797-cp36-cp36m-win_amd64.whl
To check that it has been installed sucessfully on the site-packages folder for your current python environment write:
pip freeze
It's all!
Check the version of wxpython and the version of python you have in your machine.
For python 2.7 use wxPython3.0-win32-3.0.2.0-py27 package
The problem was solved in openSuse simply with
zypper in python-wxWidgets-3_0-devel
Trying pip install before, gave me a lot of trouble (missing traits, missing wx/setup.h, https://github.com/wxWidgets/Phoenix/issues/1644, error: aggregate ‘wxGLAttributes _NullGLAttributes’ has incomplete type and cannot be defined, etc.).
wxpython failed to be installed with pipenv. Pipenv is not able to find wxpython binary so it tries to build wxpython but fails.
CXXFLAGS="-I/opt/homebrew/include" pipenv install wxpython
On my macOS M1 pipenv failed to install wxPython. After a lot of searching I found a forum post which really helped me fix the problem.

Install current development version with:
pip install -U https://github.com/robotframework/RIDE/archive/master.zip
(python < 3.9) Install current Beta version (2.0b1) with:
pip install psutil
pip install -U --pre robotframework-ride
Note that I tried to install wxPython with 'pip install -U wxPython' as per instruction
with no avail. Too many errors to list here. 🤨
I found a solution to the problem!!
I'm working on a 64b machine and Windows 11 operating system using VSCode.
Here is the solution using PowerShell:
Version specs:
pip 22.3.1
virtualenv 20.15.1
python 3.10.8
Create a new virtual environment in the directory where the program resides and
activate. There must be no modules installed.
virtualenv venv
venv/scripts/activate.bat
Install the following in sequence:
pip install pygame
(Not sure why pygame must be installed first, but this was
recommended and it works) 😟
pip install -U wxPython
SUCCESS!!! 🤠
These are the modules installed:
numpy 1.24.1
Pillow 9.4.0
pip 22.3.1
pygame 2.1.2
setuptools 65.4.0
six 1.16.0
wheel 0.37.1
wxPython 4.2.0
VSCode still reports wx as a missing module even when you activate the virtual
environment within. Running the code from the PS command prompt within the virtual
environment is the only working solution.
PS. I am sure there are some conflicts when trying to install wxPython within an
environment where all the other modules are installed.
I'm a Windows user of Python. I used pip to install packages, and I have about a dozen of packages in Python global package repo. However, there were packages I could not install using pip, e.g: numpy, scipy, matplotlib, lxml. To my understanding, installing package by pip requires compiling, and installation failed because they could not be compiled for some reason.
For the workaround, I installed using the installer (.exe) files of the packages. They work all fine, and appear in Control Panel list of installed program as such:
Recently, I can install/update all package smoothly with pip, which I think because I installed Cython and/or have MinGW GNU compiler in PATH. However, seems that pip keeps its own version of installed packages: e.g. pip list still shows matplotlib-1.3.1, numpy-1.7.2 etc.
I test by: pip install -U lxml, lxml in pip list becomes 3.4.1, but the 3.3.3 in the Control Panel is still there. Looks like I'm having 2 version of lxml.
Another test: matplotlib-1.4.2 (latest) was installed by exe installer. But under pip's view it's still 1.3.x. Now calling pip install -U matplotlib, this invokes the latest matplotlib, numpy and some other packages being downloaded, compiled and installed. Only after that, pip list returns the latest version number.
So why this strange behavior? (However import call always result in the later version installed). Should I uninstall all the packages by exe installer and reinstall them by pip for "consistency"?
In the pip way, although installation finished successfully, the compiler threw a bunch of warnings for some packages.
