When launching Juypter from Anaconda I receive the following error message:

Any thoughts?
Try this in Anaconda prompt
pip install --upgrade jupyter_client
pip install --upgrade jupyter_client
This package provides the Python API for starting, managing and communicating with Jupyter kernels. The above code will upgrade jupyter client.

I am new to python and jupyter notebook and I am using windows. Recently I installed Anaconda Navigator 2.3.1 and the python verson 3.9.13 on my computer. After entering the command jupyter notebook on the command-line, my browser doesn't open jupyter notebook, instead that showing me this error message:

from base64 import encodestring
ImportError: cannot import name 'encodestring' from 'base64' (D:\Anaconda3\anaconda3\lib\base64.py)
I don't understand what should do now? And how to solve this issue! Please help..........
base64.encodestring was deprecated since python 3.1 and finally removed in 3.9
You can compare the official documentation for the base64 library for version 3.8 and 3.9
https://docs.python.org/3.8/library/base64.html
https://docs.python.org/3.9/library/base64.html
I'm not sure exactly how you installed anaconda navigator but i would suggest using the latest distribution of anaconda which includes navigator
This error is caused by nbformat. Check your nbformat with the command 'pip freeze', and look for the nbformat version. Most likely your version is anterior to 5.1.3.
Upgrade to that version with the following command:
pip3 install nbformat==5.1.3
or just 'pip install nbformat==5.1.3' ; depending on your configuration.
It should fix the issue.

When I click on Jupyter Notebook in Anaconda Navigator, I am receiving this error. I was just using Jupyter Notebook and had no issues. I restarted my computer and now I am receiving this.

import textdistance
ModuleNotFoundError: No module named 'textdistance'
Can someone please suggest me what should I do
EDIT
I followed what "CanciuCostin" suggested in the comment.
And now I'm getting the following:
I tried conda install -c anaconda qtconsole and conda update qtconsole as well. But still the message is there.. :/
I had the same error today - with the last line about textdistance. I used conda to install text distance from the same environment as spyder and now I can open Spyder again.
conda install textdistance
My anaconda environment uses Python 3.
Well.. I used conda uninstall qtconsole and then once the uninstallation is complete, I installed it again by the command conda install qtconsole. But then I had to install spyder as well ( conda install sypder ).
Then it worked. But I had to install some libraries like scipy ( conda install scipy )
I am trying to use a Python program written for Python 2.7. I am using a Macbook Pro running Catalina. The program is here: https://github.com/geoss/censumander. The program has two Jupyter Notebooks to practice with. I have Anaconda 4.9.2 installed and pip 20.2.4. When I open Jupyter Notebook it defaults to Python 3 and has no kernel option to change to Python 2. I have used the guide here to try to install the Python 2 kernel: https://ipython.readthedocs.io/en/latest/install/kernel_install.html.
When I run
python2 -m pip install ipykernel
I get back
Could not find a version that satisfies the requirement ipykernel (from versions: )
No matching distribution found for ipykernel.
I am pretty new to using Python (typically use R) and am trying to get the hang of stuff like this, so apologies if the answer here is obvious. I've tried the solutions here to no avail: Jupyter notebook with Python 2 and Python3 Kernel
I have also tried the solutions here: Jupyter Notebook - install python 2. The first solution
$ python2 /path/to/jupyter-notebook
is unclear to me as I don't understand to what file path the code points (for jupyter_notebook). (This is likely a consequence of my noobiness.)
The second,
conda create -n ipykernel_py2 python=2 ipykernel
conda activate ipykernel_py2
python -m ipykernel install --user
triggers the following traceback after the third line:

Thanks, all.
From version 5.0 ipykernel only runs on Python 3.4+ (from version 5.2 — 3.5+). To install ipykernel` for Python 2.7 you need an older version:
python2 -m pip install 'ipykernel<5.0'
For backports.functools-lru-cache install or force-reinstall it:
pip install -U backports.functools-lru-cache
or
pip install --ignore-installed backports.functools-lru-cache
I was having issues installing a package. I cancelled the install mid-solving environment.

Jupyter notebook format depends on the jsonschema package:
https://pypi.python.org/pypi/jsonschema
Please install it first.
I tried installing jsonschema and importlib_metadata via conda install. When I do that, I receive this (for both):
# All requested packages already installed.
I tried turning it off and on again; I tried removing and reinstalling Jupyter. Neither worked. This is abhorrently frustrating. What the heck is going on, and why is Jupyter suddenly deciding to not work when it worked perfectly before the weekend? And more importantly, how do I fix this?
