I use Spyder 5 (Python 3.7.9), although I also installed Python 3.9 but not with Spyder.
When I press F8 to run a Static Analysis Code, a message displays:

Before installing Spyder 5 (I had Spyder 3), it worked, but since I've updated Spyder, it won't anymore.
Thank you!
(Spyder maintainer here) This is a bug in our Windows installer and we'll try to fix it in our next version, to be released in June.
It look like you're in fact using python2 and not python 3.7. Your default python might be python2 so you should try using python3 instead of python when launching commands, or try changing the default python for your system (if at all possible).

I am totally new to Python/Jupyter notebook.
Using Windows 11. I installed latest version python Python 3.11.1. Also latest Anaconda - conda 22.9.0.
My jupyter notebook (installed by anaconda) does not start from command line:

Conda documentation states "Anaconda supports Python 3.7, 3.8, 3.9 and 3.10. The current default is Python 3.9."
Should I just downgrade my python to 3.9 or 3.10 (I dont care) ?? Any other work arounds?
Updates
Could open the jupyter notebook from the conda prompt. Not stated using it yet. So lets see. If python compatibility issues need to be resolved - need to figure it out.
But, cant start the anaconda-navigator. When I try start from windows start menu - does nothing. From Conda prompt: I get the flwg error on the prompt: >anaconda-navigator Traceback (most recent call last): File "C:\apps\anaconda\Scripts\anaconda-navigator-script.py", line 6, in <module> from anaconda_navigator.app.main import main File "C:\apps\anaconda\lib\site-packages\anaconda_navigator\app\main.py", line 19, in <module> from anaconda_navigator.app.start import start_app File "C:\apps\anaconda\lib\site-packages\anaconda_navigator\app\start.py", line 15, in <module> from qtpy.QtCore import QCoreApplication, QEvent, QObject, Qt # pylint: disable=no-name-in-module File "C:\apps\anaconda\lib\site-packages\qtpy\QtCore.py", line 15, in <module> from PyQt5.QtCore import * ImportError: DLL load failed while importing QtCore: The specified procedure could not be found.

But when I use pip install the library is installed, but it still doesn't work in PyCharm.
Thanks for help! And sorry for my english.
you can try to download corresponding pacages in '.tar.gz' format on this link
manually unzip it
enter the unzipped folder
install the package through the following cmd command:
python setup.py install
here I suppose you are using windows and your python is above 3
If you are continuously encontering this problem,I suggest you alter the original download channel to a mirror.
If you installed the library through terminal and Pycharm still doesn't recognize the library, I think may be you should select the correct interpreter for the project by clicking the project interpreter at the bottom right in a Pycharm project. Look at the image in this
link. Click on the Interpreter which is named just "Python 3.x", it may work then.
["3.x" as in which version of python you are using]
I am trying to use tensorflow for research in my macbook. I use pip3 to install tensorflow in the system (not in virtual environment).
At first, I just want to verify tensorflow can be correctly imported via python3 in terminal. However, sometimes, I got the following problem when importing.

This error could only be solved if I ran the following code firstly before python3 execution
unset PYTHONPATH
If I didn't unset PYTHONPATH, I also found errors when checking the version of pip3 using
pip3 --version
The errors are shown as follows.

I thought it was so inconvenient to unset PYTHONPATH every time, so is there any solutions for this problem? I also want to import tensorflow in other text editor, such as Sublime and Pycharm, so I was really not sure what to do next.
I tried the same scenario. It is working fine for me. In the first error it seems your python installation is messed up. If you are using python3 in terminal, it should not refer to 2.7 libraries.
Also I dont think you require unset PYTHONPATH everytime. First thing is you dont need to setup PYTHONPATH. It seems the installation got issue.
You using homebrew in mac to install packages. If not I will say use homebrew and it will work as charm. As it adds dependency properly.
Thanks,

Is there a way i can fix this ?
Try running the script with administrative privileges. Just by looking at the traceback it looks like some cached files that pywinauto import tried to write but later on it wasn't found, and generally the script can't write the file due to permissions. If the above don't work, try installing python somewhere else (C:/Python with full privileges in order to isolate the issue)
This is comtypes issue. It will be fixed soon (EDIT: fixed in comtypes==1.1.7). You can downgrade to one of previous versions: pip install comtypes==1.1.2. Or run script as Administrator as Rodolfo suggested (disabling UAC may not help, need to say explicitly to "run as Administrator" by popup menu).
I just closed my spyder IDE on win7 64bit 64bit python2.7 after a long session.
during that last session, I had also installed a couple of new libraries via conda install. maybe that threw things off?
now when I try to start spyder again, the spyder splash screen appears briefly but then spyder doesn't open. if I try to start spyder from the command line, I get the following error:

try this download setuptools from here and install.
