I installed Django in a virtual environment. However, the nb_conda gets an error in another virtual env.
I tried to reinstall the nb_conda, and the error message output is:
Enabling: nb_conda
- Writing config: /home/run/.miniconda3/envs/d2l/etc/jupyter
- Validating...
nb_conda 2.2.1 OK

Apparently this is a traitlets defect:
https://github.com/ipython/traitlets/issues/722
That has been solved using patch 727
https://github.com/ipython/traitlets/pull/727
So updating traitlets may solved the issue
It did for I when trying to enbale jupytext:
jupyter serverextension enable jupytext
was showing the same error, doing
mamba/conda update traitlets solved the issue by updating traitlets from 5.2 to 5.3

I created my own docs for Read the Docs. See my repository
Some of my docs files are jupyter notebook so I used nbshpinx for it.
In my computer I installed all the dependencies and it works great when I use make html.
However, Read the docs throws the error:

Following this tutorial I created two yml files and the error changed to:
Error
Problem in your project's configuration. Invalid "conda.environment": environment not found
Solved it!
I followed this tutorial
I added in readthedocs.yml:
python:
version: 3
install:
- requirements: docs/requirements.txt
system_packages: true
And then in docs/requirements.txt:
ipykernel
nbsphinx
If questions you can always check the repository where I do it.
I have just installed Anaconda and run Jupyter Notebook through command line by using jupyter notebook command. However, I am facing an issue. On the top right, I see Kernel Error.
When I click on Kernel Error, I see these lines:

I can't run any Python code on Jupyter Notebook, as I am continuing to get that error.
I have gone through numerous threads on Stack Overflow for several hours. But I can't fix the issue.
Please, help me to solve the issue. I am doing a course on Data Scince with Python. I can't move forward without fixing this issue.
Update 1:
I have visited this Github thread and tried using the following command:
conda install -c conda-forge pywin32
conda install -c anaconda jupyter_client
conda install -c conda-forge jupyter_core
pip install --upgrade pywin32==224
However, the issue is not fixed. Instead, I am getting a new error,
ImportError: DLL load failed: The specified procedure could not be found.
This is really frustrating!
try this way, i fixed my jupyter.
same error site-packages\tornado
command
jupyter kernelspec list
from the shown result
Available kernels:
python3 D:\Programs\Anaconda3\share\jupyter\kernels\python3
open the folder, and edit kernel.json
{
"argv": [
"D:\\Programs\\Anaconda3\\python.exe", //change to your correct path
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"display_name": "Python 3",
"language": "python"
}
restart jupyter, and it will be ok.
Did you try opening the anaconda navigator from terminal and then create an environment their and install the jupyter notebook in that environment and then open the jupyter notebook from the navigator
Alright. I have managed to fix the issue. I have to write these commands:
conda install -c conda-forge pywin32
conda install -c anaconda jupyter_client
conda install -c conda-forge jupyter_core
pip install --upgrade pywin32==224
Then I got an error.
import win32api pywin32
ImportError: DLL load failed: The specified procedure could not be found.
I solve the issue by writing this command that I got from this github thread:
conda install pywin32
Now, the issue has been completely fixed!
I get this error after trying :
openmdao iprof x.py
or
openmdao iprof_totals x.py
on my terminal. Any idea why it could be? Do we have a simple sample code where the iprof works smoothly.

I looked into this and there is currently a bug when using 'openmdao iprof' and 'openmdao iprof_totals' on a version of OpenMDAO that was not installed from an OpenMDAO repository using 'pip install -e'. I put a story in our bug tracker to fix it.
I get the folowing error when I run bin/buildout.
I´ve check this issue here on Plone.org and they say that it ´s not dangerous
but they do not say how to resolve it.
I want to skip this error in order to execute bin/buildout withouth errors, til now I´m updating my products manually. How can I solve this?

You'll need to pin python-gettext to use a version before version 2.0. That version introduced syntax that requires Python 2.6 or newer (to make the package work on Python 3 as well).
In your buildout versions section, add:
python-gettext = 1.2

Create a module or package for namespace package 'plonetheme', e.g.:
mkdir -p src/plonetheme.hanging/plonetheme/hanging
touch src/plonetheme.hanging/plonetheme/__init__.py
touch src/plonetheme.hanging/plonetheme/hanging/__init__.py
src/plonetheme.hanging/plonetheme/__init__.py should contain something like:
from pkg_resources import declare_namespace
declare_namespace(__name__)
