AlreadyExistsError: File system for s3 already registered

I am running this on Jupyter Notebook with Python 3.9.12 and TensorFlow 2.6.0
Specs:
Windows 10
Python: 3.9.12
TF: 2.6.0
Keras: 2.6.0
IPython: 7.18.1
I resolved another AlreadyExistsError, which was Keras not being the same version as TensorFlow. But for this, I couldn't find an answer in particular.
Here are the simple import statements:
#import os
from object_detection.utils import label_map _util
from object_detection.builders import model_builder
#from object_detection.utils import visualization_utils as viz_utils
Here's the description of the error. What have I been doing wrong? How can I fix this?

While trying to use sklearn in Jupyter Notebook, it gives me an error. Does anyone know how to solve it?

These are the commands I am trying to launch
from sklearn.datasets import load_boston
boston = load_boston()
boston
And it returns me a plenty of errors

Honestly I am not even able to understand which is exactly the error. I had tried to reinstall again Anaconda but the situation seems unchanged. It seems that the error relies in the packages but I don't know how I could solve it.
Thanks in advance and sorry for the unprecise question.

It seems a problem with matplotlib but I've already instaled that module, and compiled the protoc files and this is the third I've trying to install tensorflow but without sucess.
Thanks to all the lads who'll reply
Thanks again, Paula

It's a bug in matplotlib. In lib/matplotlib/font_manager.py you need to change the win32InstalledFonts function to return [] instead of return None.

iPython notebook error when trying to load matplotlib

Can someone tell me what's happening and how I can fix it?

You can read about a similar issue here and here.
The main problem is with importing scimath:
"ImportError: cannot import name scimath"
You can try to import scimath.
A better solution would be to set your PYTHONPATH var, which provides the python interpreter with additional directories look in for python packages/modules. You can read more about setting PYTHONPATH variable here.

GFORTRAN_1.4 Not Found

After some fixing my PATH variable to get some library installs to work , I'm finding that my IPython Notebook (Enthought Canopy on Ubuntu 14.04) throws the following error when using the %matplotlib magic command:
ImportError: /home/joe/Enthought/Canopy_64bit/User/bin/../lib/libgfortran.so.3: version `GFORTRAN_1.4' not found (required by /usr/lib/liblapack.so.3)
I'm also getting this error when trying to install python-bio-formats, pims, and pylibtiff.
Again, any ideas are appreciated.

I was able to resolve this error by following the steps outlined here (specifically, steps 3-5): https://support.enthought.com/entries/23580651-Uninstalling-and-resetting-Canopy.
When re-attempting to install pims (https://github.com/soft-matter/pims) using pip (command: pip install --upgrade http://github.com/soft-matter/pims/zipball/master), the problem is able to be replicated. Odd.
I'm also getting a problem when trying to install pylibtiff via its setup.py script, but I will post this in another SO post, further detailing the error.

This might be late, but you can try the following thread
https://github.com/ContinuumIO/anaconda-issues/issues/686
Specifically the one by Zarhid:
conda remove libgfortran
conda install libgcc --force
replace conda with pip and modify accordingly. Worked for me
