in the last couple of days I was developing an APP on python IDLE.
I tried to import the vlc module, when I run it I get this error:
OSError: dlopen(libvlccore.dylib, 6): image not found
I installed the module with this command: pip install python-vlc.
I hope you can help me getting it work!
Thanks in advance!

python-vlc is just Python bindings for libVLC.
Without that library, it won't do you any good, because all it does is try to load that library (a .dylib, .so, or .dll, depending on your platform) and call functions out of it.
There should be installation instructions at the wiki page linked above, but on a Mac, the easiest way is to just install the VLC player. I know that if you install it with Homebrew, you get the library, in a location that python-vlc can find. But I think even the binary installer from the front page of the main VideoLAN website will work as well.
If you're using Homebrew, you'll want to read the docs for when to search brew vs. brew cask vs. other taps,1 or search somewhere like Mac App Store for the current status. But at present, the appropriate command appears to be:
brew cask install vlc
1. Generally, anything that you'd expect to find as a double-clickable app in /Applications, as opposed to a Unix command-line tool or a support library, is going to be a cask, and therefore in the tap cask, which has special shortcuts to access it. But that's a relatively new thing, and not every recipe has been converted yet.
brew install --cask vlc
Is the latest command, and it works for me!

Please excuse my lack of knowledge and poor terminology.
I am trying to get python-socketio-client running on my PI3B. It is used by some python code, not written by me, that takes selected data from Volumio3.x's API (under Buster), and passes it to my audio preamp controller to display it. The current Artist and Song Title.
It all worked on my PI2B with a version of Volumio 2.x under Jessie.
All my attempts to install python-socketio-client have errored.
I was wondering if I should install it with python3, and if so how?
Thanks
To install python packages usually you have to run pip install -m package-name
For Volumio if you check documentation (pyvolumio package) is this the one you are trying to use?
Only Python 3.7 and above are supported.
As you can see in: https://pypi.org/project/pyvolumio/
I have uninstalled Python and now I cant install it anymore (error 0x800705b4). Has anybody encountered this error ? I have tried different versions but nothing works.
You can try Anaconda for Windows which has seperate environments.
The solution I would recommend though is to use WinPython, which after install is just a folder with everything you need, doesn't change a thing in your windows environment and still works great! There is also a version that comes with the most used packages already installed, give it a try!
No need to mess with environments, just use a different WinPython folder for your projects!
Got the same error after a little digging I found the below thing...It works like a charm...
First...Make sure to check the setup package for your system which is X86 or x64, download packages based on the system before you proceed, otherwise, the hack won't work. The below is explained for x64 bit windows 8.1 system with a 64 bit Python setup package use the below-mentioned setup name(.exe file) in Step1: and search in google for downloading the Python setup
Start CMD as Admin, after that
Step1: ~YourFilePath/python-3.5.0-amd64.exe /quiet InstallAllUsers=1 PrependPath=1 Include_test=0
Step2:
~YourFilePath/python-3.5.0-amd64.exe
~YourFilePath stands for the location of the python-3.5.0-amd64.exe file on your PC Example: E:\Softwares\python-3.5.0-amd64.exe
now after executing Step2: the setup will run without any errors..... Cool...
The above-mentioned steps should work or else If you find any difficulties please visit here which explains the process in detail. Good Luck...

Eventually what did the trick for me was to roll back the previous microsoft update (KB4512575)
I'm actually using Python for an audio steganography project but I have some troubles.
I searched this error code on the forum, but I found things about SQL installations and not Python.
I'm trying to re-install Python 3.6.5 after an uninstall, because of a bug with pip.
I installed Python 2.7, Python 3.6.5, Python with VS 2017, before uninstall it because it wasn't working.
However, when I'm runing the installer as an administrator, hit "customize installation", tick everything excpet "balblalblabal (this requires VS 2015 or later)", and click on "install", it tells me that :

I realy need Python to work and I'm now stuck ...
If anybody here could help me, it would be nice !
Thanks all,
maleik.
PS : I have the log for you :*
The log link
I found this in the log file which you have attached. Try cleaning the registry with CC cleaner and give it a try. If it still doesn't work, try installing python with web installer Python Web Installed 3.6.5.

I installed python from Microsoft store after facing this problem and it magically got installed without any error as it may have directly been installed. I don't know but try if it eorks for you too.
You need to run the installation as a local administrator.
I had the same problem installing Python version 3.9 for the first time on my Windows 10, as this same problem happens to many users trying to install Python, the best solution I accidentally, just like #MANAN AGGARWAL discovered trying to check if I already had a version of Python installed on my computer by the DOS Command Prompt, was:
Open the DOS Command Prompt (cmd) and dictate "python": if a screen shows you a version, it's clearly not the first time you've installed Python, so if you want to upgrade you should try: https: / /www.delftstack.com/en/howto/python/how-to-update-python/ But if you've never installed any version of Python, the solution lies in updating your operating system to the latest version through Windows Update, and open the command prompt and type Python, or go directly to the Microsoft Store and search for Python followed by its latest version. It works without error.
** If by chance it does not automatically install on your PC after downloading, click "install on my devices" and select your computer name.
Why can't I install Python directly from the website file? Please note that when trying to install any software/applications from outside Microsoft's trusted locations, there are high chances of user settings interfering with the installation. When coming, for example, from the Microsoft Store, a chance of success is much greater, even without having problems related to User Permission Settings.
Another important thing to point out here is that installing a lot of software from outside Microsoft's trusted platforms can cause you to change some user permissions which can have positive effects with some software and negative effects with others, even with security your own system if you don't know what you're doing.
it's simple , Try Lower Version Like 'Python 3.6' but Download web install.
install it , then install last python version.
your python will update.
I've faced same/similar problem with installing Python 3.9.12 in a clean Windows 8.1 64-bit (VirtualBoxed test environment).
I thought the issue could have been fixed in a newer version of Python, but the freshest 3.10.10 fails with same issue.
The original log isn't available any longer, but luckily it is quoted in another answer, and the following line reveals the real problem:
Applied execute package: core_AllUsers, result: 0x80070643, restart: None
My log looks the same, and if you scroll the log up, you'll discover that core_AllUsers is a UCRT MSI-installer, which is downloaded from Python site (for 3.10.10 64-bit the link may look like https://www.python.org/ftp/python/3.10.10/amd64/ucrt.msi).
If you download it manually (Python installer is smart enough to do a cleanup even if it fails, so you won't find this MSI in a local cache) and run, it will probably crash. And if it is your case, I have a simple solution - just install update KB2999226 (Update for Universal C Runtime) for your OS, which you can download from Microsoft.
I also faced the similar issue. What the trick worked for me is I installed it for the individual user (as earlier installation was for the all users).
So earlier if one has installed it for the all users then install it for the specific user and vice versa.
I know this is not the resolution of the error faced. However, this approach will install Python which is the main motive to achieve.
I encountered the same issue after installing a fresh Windows 8.1 on my PC.
I solved that by using the Python v3.9 web installation file which you can find here.
However, you can choose any other version that has a web installation file
Note: You need internet connection to use this method.
I'm a complete beginner in Python programming. I have trouble installing/importing the module 'requests' on python. When I use my command terminal to install requests, I get a message that requests is already installed. However, when I try to import requests into the file I'm working on, python tells me there is no such module installed.
Sorry to bother you with this silly and probably easy question, thanks in advance!
If you use PyCharm (which is a great choice in my opinion), go to the tab Run and select Edit Configuration and in the window that just opened make sure the your Python interpreter is the one you used when you pip installed the package you asked about.
You can check your Python version or just see in PyCharm if the requests is actually installed by going to the tab File, select Settings, click on Project: name_of_your_project and finally check in Project Interpreter that the package is installed.
I'm just starting out with Python, and have found out that I can import various libraries. How do I find out what libraries exist on my Mac that I can import? How do I find out what functions they include?
I seem to remember using some web server type thing to browse through local help files, but I may have imagined that!
From the Python REPL (the command-line interpreter / Read-Eval-Print-Loop), type help("modules") to see a list of all your available libs.
Then to see functions within a module, do help("posix"), for example. If you haven't imported the library yet, you have to put quotes around the library's name.
For the web server, you can run the pydoc module that is included in the python distribution as a script:
python /path/to/pydoc.py -p 1234
where 1234 is the port you want the server to run at. You can then visit http://localhost:1234/ and browse the documentation.
Every standard python distribution has these libraries, which cover most of what you will need in a project.
In case you need to find out if a library exists at runtime, you do it like this
try:
import ObscureModule
except ImportError:
print "you need to install ObscureModule"
sys.exit(1) # or something like that
You can install another library: yolk.
yolk is a python package manager and will show you everything you have added via pypi. But it will also show you site-packages added through whatever local package manager you run.
just run the Python interpeter and type the command
import "lib_name"
if it gives an error, you don't have the lib installed...else you are good to go
On Leopard, depending on the python package you're using and the version number, the modules can be found in /Library/Python:
/Library/Python/2.5/site-packages
or in /Library/Frameworks
/Library/Frameworks/Python.framework/Versions/Current/lib/python2.6/site-packages
(it could also be 3.0 or whatever version)...
I guess it is quite the same with Tiger
Considering that in every operating system most of python's packages are installed using 'pip' (see pip documentation) you can also use the command 'pip freeze' on a terminal to print a list of all the packages you have installed through it.
Other tools like 'homebrew' for macOS (used when for some reason you can't install a package using pip) have similar commands, in this specific case 'brew list'.
