AttributeError: 'version_info' object has no attribute '__version__' when trying to load Yolo Model Weights

I am trying to follow this video: https://www.youtube.com/watch?v=_UqmgHKdntU
I cloned the github repository, and then I downloaded the weight files. I also created a virtual environment with python 3.6.0 (because Python 3.9.2 was giving error due to incomaptibility with Tensorflow version 2.2 which was in the requirements.txt file)
However, when I tried to load the weights with the following command,
python load_weights.py
I am getting this error,
__version__ = __version_info__.__version__
AttributeError: 'version_info' object has no attribute '__version__'
I tried to find this a lot on Stackoverflow and other places on Google but could not find anything that worked for me.
The complete error is given below,

One of the solutions on Stackoverflow told me to change pyparsing library, unknown version in python library pyparsing
Edit: I checked the pyparsing version using the command pip show pyparsing, which displayed the following results,

I also tried to uninstall the pyparsing and again install the specified version, but the problem still persisted.
Another solution asked me to also install the tensorflow-gpu which was given on the Github repository,
pip install -r requirements-gpu.txt
I tried this however this also did not work. I also tried to uninstall and install Tensorflow again, but again the same error persisted.
I also tried to upgrade my pip by using this,
python -m pip install --upgrade pip
This showed me the message that,
Requirement already satisfied: pip in e:\hassan\semester 8\research\example4\object-detection-api\venv\lib\site-packages (21.3.1)
However, at the end, it said that new version is still available (but it wouldn't install it, I don't know for what reason)

According to one of the posts, upgrading pip solves the problem. I tried to upgrade but it neither upgraded the pip version nor did it solve my problem.
Can anyone help me solve this version error?

Pycharm: Fails to make venv based on python 3.9.01+ [duplicate]

I setup a new Debian 10 (Buster) instance on AWS EC2, and was able to install a pip3 package that depended on netifaces, but when I came back to it the next day the package is breaking reporting an error in netifaces. If I try to run pip3 install netifaces I get the same error:
~$ pip3 install netifaces
Collecting netifaces

Complete output from command python setup.py egg_info:

AttributeError: 'HTMLParser' object has no attribute 'unescape'

HTMLParser().unescape was removed in Python 3.9. Compare the code in Python 3.8 vs Python 3.9.
The error seems to be a bug in setuptools. Try to upgrade setuptools. Or use Python 3.8.

I was facing this issue in PyCharm 2018. Apart from upgrading setuptools as mentioned above, I also had to upgrade to PyCharm 2020.3.4 to solve this issue. Related bug on PyCharm issue tracker: https://youtrack.jetbrains.com/issue/PY-39579
Hope this helps someone avoid spending hours trying to debug this.

I had python3.6 and related packages through deb management.
Needed python3.9 for side project and the solution to fix pip and AttributeError: 'HTMLParser' object has no attribute 'unescape'
was to update pip for python3.9 locally for one user:
python3.9 -m pip install --upgrade pip
now installing python3.9 version of the pip-packages work:
python3.9 -m pip install --target=~/.local/lib/python3.9/site-packages numpy

Downgrading to any older python3 version is not the solution and most of the time upgrading setuptools won't fix the issue. The proper solution that worked for me to work with pip using python3.9 is the following on Ubuntu18:
locate /usr/lib/python3/dist-packages/setuptools/py33compact.py33
and change
# unescape = getattr(html, 'unescape', html_parser.HTMLParser().unescape) # comment out this line
unescape = getattr(html, 'unescape', None)
if unescape is None:
# HTMLParser.unescape is deprecated since Python 3.4, and will be removed
# from 3.9.
unescape = html_parser.HTMLParser().unescape

Python3.7 on Windows Ubuntu Bash shell ImportError: cannot import name 'HTTPSHandler' from 'urllib.request' (/usr/lib/python3.7/urllib/request.py)

I've recently updated Python to version 3.7 from version 3.5, and made it the default in my bash shell. I've also updated pip and made sure it uses Python3.7.
Now, whenever I try to install any module using pip I get this error"
$pip3 install google

I get the same error if I try to simply run pip. This didn't happen when I was using python3.5. I did have this problem when briefly using python2.7, but I fixed it using https://askubuntu.com/questions/581999/pip-raises-importerror-cannot-import-name-httpshandler. That solution doesn't seem to work for python3.7.
I've tried to reinstall pip, reinstall python3, update my Windows Ubuntu subsystem, and reinstall libssl-dev. I'm stumped. Any help is appreciated!

You must have inadvertently upgraded your system pip (probably through something like sudo pip install pip --upgrade)
pip x.x adjusts where its internals are situated. The pip3 command you're seeing is one provided by your package maintainer and is not a file managed by pip.
You can read more about this on pip's issue tracker
You'll probably want to not upgrade your system pip and instead use a virtualenv.
To recover the pip3 binary you'll need to sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall.
It should work fine if you use the first approach python3 -m pip ... instead of pip3 ....

Virtualenv package upgrade and install fails: cannot import name Message

I try to upgrade pip within a virtualenv following the instructions here. The upgrade fails because the system python cannot import the name Message from the email module.
(newsfeed)myhost:newsfeed admin$ pip install --upgrade pip
Traceback (most recent call last):
File "/Users/admin/newsfeed/newsfeed/bin/pip", line 7, in <module>

from pip import backwardcompat
File "/Library/Python/2.7/site-packages/pip/backwardcompat/__init__.py", line 69, in <module>
from email import Message as emailmessage
ImportError: cannot import name Message
This problem is not just with upgrading pip but with installing anything within the virtualenv. When new package installations are attempted the same error occurs.
In a python terminal outside the virtualenv Message cannot be imported, but inside the virtualenv it can.
Also, in a different virtualenv on the same machine, there is no error installing or upgrading packages.
Why can't this virtualenv upgrade or install packages?

The standard library's email package is being shadowed (hidden) by a package or module named email(.py) in your path.
Locate the package by calling
python -c 'import email;print(email.__file__)'
and rename it or remove it.

Your pip is not inside the venv so you will probably not be able to upgrade it like this.
This is caused by the fact that you created a venv that uses system-packages. Remove the venv and recreate it by adding --no-site-packages as a parameter.

How to use Python 3 (3.5) as the default interpreter in my virtual environment?

I ran into problems when I installed Python 3.5 on Mac. I wanted to use Python 3.5 as the interpreter when I ran my Django development server. I got this issue when I tried it (I know I must install a virtualenv, read below):
$ python3 manage.py runserver
Traceback (most recent call last):
File "manage.py", line 7, in <module>
from mezzanine.utils.conf import real_project_name

from django.conf import global_settings as defaults
ImportError: No module named 'django'
The first was when I tried installing pip packages it installed by default on the Python 2.7 in my virtual environment:
pip install django==1.9rc2
Collecting django==1.9rc2
Downloading Django-1.9rc2-py2.py3-none-any.whl (6.4MB)
100% |████████████████████████████████| 6.4MB 66kB/s
Installing collected packages: django
Successfully installed django-1.9rc2
I use Django so I tried also install a virtual environment for the first time. First I tried it with pip, but that didn't work.
So how do I setup so that my Python3.5 is the default usage when using Python interpreter and in my virtual environment? I can't figure this out or I have done something wrong in my process.
Edit:
Thanks for the answer and comment. I tried with the both solutions and the same error persisted. See output below:

ImportError: This package should not be accessible on Python 3. Either you are trying to run from the python-future src folder or your installation of python-future is corrupted.
My virtualenv version: 13.1.2

Your error is related to a known virtualenv bug regarding python-future and mixing up the 2.7 and 3.x module paths, the solution is to downgrade virtualenv to a version < 12.04, 12.0.2 is suggested in the link.

Firstly, If you are going to use multiple versions of python,then you must use Virtual Env.Also then Create your virtualenv using the following command so that it uses python 3.5 as default environment :
virtualenv -p python3 envname
and then install django in the virtualenv.after activating your virtualenv
