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!

Not able to install packages that rely on Tensorflow on Mac M1

I successfully installed Tensorflow 2.7.0 on my MacBook with an M1 chip following this guide by Apple: https://developer.apple.com/metal/tensorflow-plugin/
I now want to install a package (ethnicolr) in a project that relies on Tensorflow >=1.15.2. This should not be an issue, but it sadly is.
requirements.txt of my project
pandas==1.3.4
ethnicolr==0.4.0
requirements.txt of ethnicolr:
tensorflow>=1.15.2
Running pip install -r requirements.txt yields
ERROR: Could not find a version that satisfies the requirement
tensorflow>=1.15.2 (from ethnicolr) (from versions: none) ERROR: No
matching distribution found for tensorflow>=1.15.2
Running pip list shows, that Tensorflow was installed. But it's not called tensorflow, but tensorflow-macos or tensorflow-metal.
tensorboard 2.7.0
tensorboard-data-server 0.6.1
tensorboard-plugin-wit 1.8.0
tensorflow-estimator 2.7.0
tensorflow-macos 2.7.0
tensorflow-metal 0.3.0
What is a solution here? There must be more packages out there with the requirement of Tensorflow...

So I got it to run. I'm not sure if this is ideal but I'm sharing my solution to maybe help anyone running into the same issue. I installed tensorflow 2.6.0 in a virtual environment using conda / mambaforge. I opted for 2.6.0 because 2.5.2 is not available for M1 and 2.5.0 wasn't working. You can read about installing Mamaforge here. After that, I installed Tensorflow with
conda install tensorflow==2.6.0
I also set the pandas version to pandas>1.2.3 in the requirements.txt of my own project (same as in ethnicolr). This resolved to pandas 1.3.3.
Next, I had to solve the dependency issue with ethnicolr, since ethnicolr requires tensorflow 2.5.2. I did that by forking the ethnicolr repo and creating a branch where I pin the tensorflow version to 2.6.0 in the requirements.txt and setup.py. You find this branch over here. To use this github branch, I changed the line in my requirements.txt to:
git+https://github.com/ospaarmann/ethnicolr.git#apple_m1_support_tensorflow_2_6_0#egg=ethnicolr
Now I had an issue with a dependency mismatch with numpy. It is described in this StackOverflow thread. What happened was that importing pandas or ethnicolr would throw this error:
>>> from ethnicolr import census_ln, pred_census_ln, pred_wiki_name
Traceback (most recent call last):

File "pandas/_libs/interval.pyx", line 1, in init pandas._libs.interval
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject
The solution here is to just ignore the dependency issues and manually install a newer version of numpy. It doesn't work when I set the numpy version in my requirements.txt because this throws a dependency error:
ERROR: Cannot install numpy>=1.20.0 and tensorflow==2.6.0 because these package versions have conflicting dependencies.
The conflict is caused by:
The user requested numpy>=1.20.0
tensorflow 2.6.0 depends on numpy~=1.19.2
So I just installed it with python -m pip install numpy==1.20.0. And now everything seems to work.

MetPy vs Pint package compatibility error

In my Conda environment, when I run pip show MetPy, my first and last two lines are:
Name: MetPy
Version: 1.0
...
Requires: scipy, matplotlib, pandas, pyproj, pooch, importlib-resources, traitlets, importlib-metadata, numpy, pint, xarray
Required-by:
When I run pip show pint, my first and last two lines are:
Name: Pint
Version: 0.16.1
...
Requires: packaging, importlib-metadata
Required-by: MetPy
These should be the latest versions of these packages. Yet, when I try to do...
import metpy.calc as mpcalc
...I get the following error:
Traceback (most recent call last):
File "redacted.py", line 17, in <module>

% (func.__name__, count_params, len(args))
TypeError: find_intersections takes 5 parameters, but 3 units were passed
This makes me think I'm missing something with my package updates. Is there another dependency I'm missing?

It appears likely that you might not have pip installed within your conda environment or that you are running pip from somewhere outside your conda environment, and so pip show might be misleading you. Check your versions of MetPy and Pint within your conda environment with conda list, as this should be a version conflict error between older versions of MetPy (<=0.11.1) and newer versions of Pint (>0.9).
conda install -c conda-forge metpy==1.0 should get your conda environment caught up to MetPy 1.0.

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:
~$ jupyter notebook
Traceback (most recent call last):

RuntimeError: Requests dependency 'chardet' must be version >= 3.0.2, < 3.1.0!
P.S: I uninstalled bioservices and it did not solve the error! Tried to reinstall chardet but it give the next output:
~$ pip install chardet==3.0.2
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

Can't correctly import six module via pip when I was installing easy install
