Idle3 editor fail to open in Fedora 36

I am currently unable to open Idle3 editor. I am running Linux Fedora 36, when idle3 command is issued I get this:
Traceback (most recent call last):
File "/usr/bin/idle3", line 3, in <module> from idlelib.pyshell import main
File "/usr/lib64/python3.10/idlelib/pyshell.py", line 53, in <module> from idlelib import debugger
File "/usr/lib64/python3.10/idlelib/debugger.py", line 7, in <module> from idlelib import macosx
File "/usr/lib64/python3.10/idlelib/macosx.py", line 7, in <module> from test.support import requires, ResourceDenied
ModuleNotFoundError: No module named 'test'
I don't know how to solve it.

Fortunatelly the trouble with Idle3 was solved in the recent update of Fedora 36, I think the missing file was inserted.

ImportError: cannot import name 'KernelProvisionerBase' from 'jupyter_client.provisioning'

Very messy tonight. It was working fine before until I tried to upgrade tensorflow to 2.6. it failed, then all other packages also broke. for example, I cannot launch jupypter notebook. I did try to upgrade it by using conda update jupyter. Thanks for your help.

ok, i ended up solving this after:
conda update --all

I have broken my poetry installation, and I don't know where to begin to fix it

I was using poetry in combination with pyenv for some hobby projects. I created some virtualenvs with pyenv inside some poetry hobby projects. For some reason, I deleted some of these python installs that broke the virtualenvs within these projects and now poetry won't work anymore. I'm getting this message when I try to start poetry. I'm using Linux Mint 20.1:
/home/milkman/.poetry/lib/poetry/_vendor/py2.7/subprocess32.py:149: RuntimeWarning: The _posixsubprocess module is not being used. Child process reliability may suffer if your program uses threads.
"program uses threads.", RuntimeWarning)

I have no idea where to start to fix this. Anytime I try a command with poetry I get this same message. Can anyone point me in the right direction?
Thank you!

May be you have deleted some library files. You can try removing poetry and all libraries that your app is using. Start fresh installation of poetry.
You can use pip to install and uninstall.
Other wise start a new project from fresh.

It appears you accidentally deleted some of the library's functions. Try just removing it and reinstalling.

import CommonMark
ModuleNotFoundError: No module named 'CommonMark'
Acutually I found these error on this web and tried to install the r-commonmark 1.4 but it does not work well now.
Please tell me how to deal with it.

CommonMark is a package that Orange used. It was renamed in the latest release what causes that imports do not work. The issue should be solved by installing newer Orange3 version3.16.0

Cannot run anaconda

I just installed anaconda and I have udpated the PATH variable.
However, I cannot run any conda related commands.
Every time I run a command starting with "conda" I get the following error.
Can anyone help?
I am using macOs High Sierra 10.13.6.

I seem to recall something similar when I first ran Anaconda on my Mac as well. I believe I solved it by doing two things:
Uninstalling Anaconda (Link)
Reinstalling Anaconda (potentially in a different location, say, under your User home)
I think in the process of installation my PATH pointed finally to a different location than the Conda/Python install.
