Issue when installing the Spacy python package

I tried to install the Spacy package using the conda terminal with the command:
"conda install -c conda-forge spacy"
Even though the installation seems to be working, when I use Jupyter Notebook and import spacy I get the following error:

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?

"import matplotlib.pyplot as plt" not working - UnicodeDecodeError

Using Jupyter notebook via Anaconda2 on a Windows7 OS 64-bit launching it with GraphLabCreate. Getting the following error when executing the command "import matplotlib.pyplot as plt".
Is it anything to do with the environmental variables as I'm using GraphLabCreate? They have the following from a tool bar command selection:
set "PATH=C:\Users\Owner\Anaconda2;C:\Users\Owner\Anaconda2\Scripts;%PATH%"
I've gone ahead and checked the environmental variables and they are listed as above (except for the %PATH% part). Here are the PATH variables on my computer:

Import Theano on Anaconda of platform windows10

I download the theano from github, and install it.

When I get into the files, I indeed can not find configparser.py in the directory, but the original file do not have it neither.
ImportError: cannot import name 'configparser'

Just found the temperary solution , rename configparser.py to config_parser or any other name that are not confilct .
and change name of each module include it to config_parser .

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.
