Please help in resolving this error.
Numpy is already installed.
Use pip to install the numpy first.
Copy and run this code in your first cell.
!pip install numpy
If you need to upgrade pip then copy and run the below command in your first cell followed by the above command.
!python3 -m pip install --upgrade pip
You may have to restart your kernal after updating pip. Use restart option from Jupyter Notebook kernal option. see screenshot for reference.
Another Option
If you want to downgrade your python from 3.10 to 3.9, as numpy is yet not supported by python 3.10. Then you can downgrade your python version from 3.10 to 3.9 via conda.
!conda install python=3.9
I have tried to rectify this issue by using
pip install opencv-python
pip install opencv-contrib-python
pip uninstall panda
pip install panda
conda install opencv-python
Some info is that im currently using python 3.6.10 and Windows 10.
opencv-python 4.2.0.32
numpy 1.18.1
panda 0.3.1
tensorflow-gpu 1.14.0
I created a new env but cant seem to import cv2 over on Jupyter Notebook. My earlier environment was able to do so. When i tried to pip install the opencv-python==4.1.2.30 (from the old environment's pip list), the problem was still there. Thank you for reading!
Firstly check which pip you are using
which pip # for linux
where pip # for windows
If path is in your new enviroment then try to reinstall it else first set PATH of new enviroment pip to the terminal/command prompt.
I found the elementary mistake I made. I forgot to download jupyter notebook in my env. As a result, I think it brought me to the another directory which doesn't have opencv. Thank you pygirl and nitr_himanshu for your help!
I am a beginner at computers. I use Anaconda python 3.6 in windows 10. I have already installed OpenCV using this command:
pip install opencv-python
But when I try to import cv2 using this:
import cv2
this error shows up:
How can I install openCV for python?
Based on python opencv link: https://pypi.org/project/opencv-python/
Step 1:
Uninstall the opencv first if you have previous/other manually installed (= not installed via pip) version of OpenCV installed (e.g. cv2 module in the root of Python's site-packages)):
pip uninstall opencv-python
Step 2:
Install the package afresh
pip install opencv-python
Hope that works!
try this:
Create Virtual Environment
conda create --name opencv-env python=3.6
Activate the environment
activate opencv-env
Install OpenCV and other important packages
pip install numpy scipy matplotlib scikit-learn jupyter
pip install opencv-contrib-python
pip install dlib
Test your installation
import cv2
cv2.__version__
In my case, using Python 3.8 on Windows 10 and Pycharm (or VS Code as well), I have this same issue.
Finally I noticed that the Antivirus (Nod32) deletes the cv2.cp38-win32.pyd file that should be in the cv2 folder. I simply paused the protection, installed opencv with pip install opencv-python command and it worked just fine.
I hope it helps someone.
This happened to me because I setup a virtual environment with python 32-bit and my modules required the 64-bit version so it seemed there was a version conflict of CV. Changing the python version in my environment fixed the issue.
I was facing a similar issue. In my case, the issue occured because of previous dependencies.
!pip install easyocr
!pip install imutils
if you are running these commands first and then importing
import cv2
from matplotlib import pyplot as plt
import numpy as np
import imutils
import easyocr
then you will get this error. So you first import CV2 and then pip install easyocr or other libraries. This worked in my case.
I used the answer provided here and it worked.
By running pip install opencv_python-3.4.5-cp36-cp36m-win_amd64.whl
I had this exact same problem on Windows 10. Uninstalling via pip and then reinstalling in my virtual environment fixed everything up for me.
Here's a link that helped https://pypi.org/project/opencv-python/
Try reinstalling openCV — it worked for me.
To uninstall:
pip uninstall opencv-python
To reinstall:
pip install opencv-python
I am using Jupyter Notebook to install packages with the command: !pip install.
I just used this command to install the Options package, but it's still not showing up. I checked the default python Environment as well as the conda environment.

To install packages into jupyter notebook you have to use conda instead of pip. Just find the conda install instruction for the package you are trying to install.
For example, the command to install numpy on conda is:
conda install -c anaconda numpy
instead of the regular pip version which would've been:
pip install numpy
You can search for yours by googling: conda install <package-name-you-want-to-install>.
I'm trying to uninstall numpy & then install a specific version of it on anaconda. However, the prompt also told that others packages will also uninstall itself. How do I uninstall only numpy packages? I'm using ubuntu 18.04.
If you anaconda contain pip tool, you can uninstall numpy only through pip uninstall numpy
