VSCode debugger can not import queue due to shadowing

When I try to run any python code in debug mode using VScode, I got an error message saying:

i.e.: the module "queue" could not be imported because it is shadowed by:
/home/<username>/.local/lib/python2.7/site-packages/queue/__init__.pyc
Please rename this file/folder so that the original module from the standard library can be imported.
Deleting the init.pyc and init.py resulting with an error message about missing queue import.

Downgrading my Python extension in Visual Studio Code to v2022.2.1924087327 worked for me.
Elevating #Onur Berk's comment below as part of the answer:
Its is very easy to downgrade the python extension, just click 'extensions' and find the Python extension and select it. Rather than clicking 'uninstall' click the arrow next to it, this will give you an option to install another version

Unable to access Jupyter Notebook. ImportError: DLL load failed: %1 is not a valid Win32 application

I am trying to open Jupyter Notebook in my Windows10 system.
I had python2.7 initially in my machine and I have installed python 3.8.
I have also installed Jupyter Notebook using pip install Jupyter
The installation has been successful, but when I try to access Jupyter Notebook, I get this error:

Please help me with a solution.

Please check if the python version you are using is also 32 bit. If not then that could be the issue. You would be using a 64 bit python version.

Errors in installing django module for python

I've been trying to install django, looked around the internet but couldn't find possible solution for this.
I have tried looking for solutions. Some solutions told me to install conflict checker for pip but it still did not work because nothing seems to be getting installed using 'pip' keyword. It even gives me error when I try to find out my pip version
python -m pip install django
PS C:\Users\Fahad> python -m pip install django

So I tried downloading get-pip.py from here and hen I executed python get-pip.py then I tried re-installing django and it worked.

Problems upgrading Ipython (prompt_toolkit incompatibilities)

Trying to open a jupyter notebook file (.ipynb file)
with this command ipython notebook filename.ipynb then I am getting Below Error while using ipython..
Traceback (most recent call last):

from prompt_toolkit.enums import DEFAULT_BUFFER, EditingMode
ModuleNotFoundError: No module named 'prompt_toolkit'

Just got the same problem.
The solution for me was to pip uninstall prompt-toolkit and pip install prompt-toolkit. This uninstalled v1.0.5 and installed v2.0.4.

AttributeError: module 'errno' has no attribute 'EWOULDBLOCK'

The errno module on pypy3 on Windows (which is beta) is indeed incomplete. This has been fixed after the 5.10.0 release and will be included in the 5.10.1 release.

We build nightly zip files off the latest HEAD, available here. It would be great if you could try out the latest windows version and let us know on IRC at #pypy, or on the pypy-dev mailing list, or by filing an issue on our bitbucket issue tracker whether it works for you, so that we will not need to do a 5.10.2 bug release fix after the current one.
