cv2 not work after install mediapipe library

I want to make handtracker program using python but the tutorial tell me to install mediapipe library, then I installed it. Before that it's okay using cv2 to stream my camera, but after installing mediapipe, the cv2 doesn't work
here the message :
>>>import cv2

I tried to install opencv again but always get this message :
Requirement already satisfied: numpy>=1.19.3 in c:\users\windows\appdata\local\programs\python\python39\lib\site-packages (from opencv-python) (1.21.1)
but the problem still there. How do I fix it?
Edited : this is my pip list
C:\Users\windows>pip list

I have the same situation like above
you can try it:
pip install "opencv-python-headless<4.3"
This command has successfully resolved this situation
Reference:https://github.com/Rudrabha/Wav2Lip/issues/387

In any version(ex: 4.6.0.66), when you install any 2 of 3 packages: opencv-contrib-python, opencv-python-headless, opencv-python, make sure they have the same version. I also got the same error, I found out their versions are different. Then a synchronous update solved the problem.

I have similar problem, and I only have opencv-python installed. The problem is solved by installing opencv-python-headless.
My problem is more complicate than that. Actually the opencv-python is already installed in "root", but when I login as another user (dev), I get the problem as OP.
I can install opencv-python-headless or opencv-contrib-python manually, then the system will work. But if I install them in "root", I sill have the same problem.
So the final solution I use is to reinstall opencv-python in my user environment (dev):
pip3 install --upgrade --force-reinstall opencv-python

I fix such a problem using the following commands.
pip uninstall opencv-contrib-python
pip install opencv-contrib-python

the following solution
pip install "opencv-python-headless<4.3"
fixed the error below when building OpenCV from source!

Pip broken after upgrade. Cannot unsinstall or upgrade Pip or Python

I recently had tried to run a pip command and noticed my pip version was considerably out of date so upgraded it. This seems to have completely broken my pip install and I cannot figure out how to reset it.

I've tried 3.6, 3.7, 3.8, 3.9 and 3.10 with the same results.
I've also found some stack overflow answers suggesting to edit /usr/bin/pip3
Originally it looks like this:

if __name__ == '__main__':
sys.exit(main())
I've tried this:
from pip._internal import __main__
if __name__ == '__main__':
sys.exit(main())
and this:
I've tried this:
from pip._internal import __main__
if __name__ == '__main__':
sys.exit(__main__._main())
But neither have resolved the issue.
To be sure i'm not messed up with a local version i've tried all of the above using /usr/bin/pip3 --version rather than just pip3 --version with the same results.
Now i'm at a bit of a loss how to get a working version of Python and Pip.

I've now installed Python3.6 using "method two" from here: https://askubuntu.com/questions/1152640/apt-install-doesnt-install-python3-6 i.e. manual install
I've then upgraded pip using:
sudo python3.6 -m pip install pip --upgrade
Now pip --version and pip3 --version return an error but directly accessing the bin works:
$ /usr/local/bin/pip --version
pip 21.3.1 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)
The aliases are currently pointing to:
$ which pip
/home/sortitoutsi/.local/bin/pip
$ which pip3
/home/sortitoutsi/.local/bin/pip3
It seems that other things are now broken, such as aws.

Simply reinstalling aws sudo python -m pip install awscli seemed to have fixed the above. I'm guessing a sudo apt-get update at some point forced an upgrade of awscli after finding an updated Python installation.

Do not try and install Python versions and packages (from another ppa) that are not supported by your OS. Your system may break.
Your attempted Pip installation is, luckily, in a local directory: $HOME/.local/. Check if there is anything else installed in $HOME/.local/bin/ and $HOME/.local/lib/python3.5/site-packages/. If nothing (or nothing that seems important), rename that directory:
mv ~/.local ~/.local_aside
Now, you should have the system Pip back again.
You may lose some other packages that you installed earlier (which would now be in ~/.local_aside, but possibly, you can reinstall those. Either with a system packages (e.g., python3-numpy), or again with pip3 install numpy and the like. Though pip may have trouble finding a correct NumPy version, since Python 3.5 is not supported anymore (the system package should be fine).
If you want to use a more recent version of Python, install a local (user-only) one. My preferred way of doing that is to use pyenv, which requires some set up (installing the necessary build packages). If you use pyenv, carefully read the installation instructions for your case. Once you get it going, you can quickly install any version of Python, and between minor versions, they won't even get in the way (that is, python3.9 -m pip install numpy will be a separate installation from python3.10 -m pip install numpy, and both can happily live next to each other if so wanted).
But don't use sudo and install it as a root: your system will get confused and may break.
Another alternative is Conda, in the form (my preference) of miniconda3. Conda can and will also install C library dependencies, and actively tries to resolve version conflicts between Python packages (in case you have to install a lot of packages). Again, browse the manual to get going, but it's relatively straightforward to use, and doesn't get in the way of your OS.

conda update causes ImportError: No module named tqdm

However, when I try to install tqdm with pip, it says it is already installed:
$ pip install tqdm
Requirement already satisfied: tqdm in /usr/local/lib/python2.7/site-packages (4.32.2)
I am using Python 2.7 on MacOS Mojave with no virtual environments. How can I fix conda?
EDIT:
I also tried: python -m pip install tqdm but it says requirement already satisfied.
Then I tried: /Users/user/anaconda2/bin/python -m pip install tqdm but it also says requirement already satisfied: Requirement already satisfied: tqdm in ./anaconda2/lib/python2.7/site-packages (4.31.1)

I ended up removing and reinstalling anaconda, which fixed the problem.

If you cannot use conda to install tqdm, something is seriously messed up.
In the best of cases, it's only about environment variables. Are you setting PYTHONPATH or similar? That could interfere with conda finding its own packages.
Check your environment variables, don't set anything Python.
Execute conda activate base.
Check that python now is the one from the conda base environment.
Call conda install.
In the worst of cases, you somehow uninstalled or broke a package that conda needs. In this case, re-install Miniconda from scratch in a different directory. You should use Miniconda3 (or Anaconda3) this time, as Python 2 is only half a year away from its end of life.
Afaik, conda is able to mange existing environments from a previous installation, but I've never tried to use that feature.
If you haven't been using conda environments, but installed everything into the conda base environment, and that environment is messed up, I have no idea how to recover. You should always create custom conda environments for your projects.

for ubuntu 18.04
i faced the same issue on jupyter notebook, however the current apt install builds the 4.19 as latest which was bugged out for me.
Here are my steps for the solution:
Download the desired newer version
http://old-releases.ubuntu.com/ubuntu/pool/universe/t/tqdm/
cd to deb file location
sudo dpkg -i <filename.deb>

Runtime Error when trying to launch Jupyter Notebook (Python)

I usually work with the Jupyter Notebook Interface when programming Python but recently I installed bioservices through pip (Bioservices) and when I tried to open the Jupyter Notebook I get the following RunTime error:

P.S: I uninstalled bioservices and it did not solve the error! Tried to reinstall chardet but it give the next output:

Collecting chardet==3.0.2
Using cached chardet-3.0.2-py2.py3-none-any.whl
Installing collected packages: chardet
Successfully installed chardet-2.3.0

This looks like a broken dependency. Have you tried installing the correct version of the chardet package, e.g.
pip install chardet==3.0.2
Of course here I'm assuming you have pip installed. Otherwise you're stuck with what your system ships. In that case, I would advise installing pip or any alternative way to control you python installation on a finer level.

Apparently you have a package named chardet required somewhere, but the version of this module is deprecated. Try to update chardet with pip upgrade chardet or uninstall and reinstall it.
$ pip uninstall chardet
$ pip install chardet

I have also same error. after trying all it doesn't work for me.
so I simply uninstall it:
pip uninstall jupyter
Then again install jupyter notebook
(it doesn't remove your installed library, simply uninstall jupyter) let's try

Uninstalling and reinstalling six using pip didn't work
sudo pip uninstall six
sudo pip install six
However, I was able to solve the problem using easy_install:
easy_install --upgrade six

Reason for this is when you install Six using PIP the location of the Six library isnt added to Pythons Path so when trying to use the commands, python cant find them. Installing with Easy_Install doesn't have this problem, when it is installing six it automatically updates the python path variable so python can find the library.
Installing by Easy_Install as answered before resolves this but you can alternatively add the location to the python path variable.

I came across the same problem today, reinstalling with pip did not work and i can not do it with easy_install as it a custom package
the solution was to point the PYTHONPATH variable to the site-packages that contains the package
export PYTHONPATH=$PYTHONPATH:/path/to/sites-package
you will face this problem if you work with virtual env
