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 have already installed opencv in anaconda prompt by entering the command:
pip install opencv-python
it installed properly, but I'm unable to import the module in jupyter notebook.I entered the following command in jupyter:
import opencv
but it's showing ModuleNotFoundError
Also, to resolve anaconda environment issues, I entered the following command in anaconda prompt:
conda install -c conda-forge opencv
this further downloaded and extracted packages:
libopencv-3.4.1,opencv-3.4.1,py-opencv3.4.1
but still I'm unable to import opencv or libopencv module in my Jupyter notebook.
What should I do to use opencv3.4.2.17 in my python version3.7?
The correct syntax for importing opencv is as follows:
import cv2
If opencv was correctly installed, it should work.
For installation of OpenCV, use:
pip install opencv
To import OpenCV, use:
import cv2
I am working on Jupyter Notebook on my windows. I am trying to import module cv and cv2.
import cv
produces this error.
ImportModuleError: No module cv
Similarly for
import cv2
it produces the error :
ImportModuleError: No module cv
Please help me solve this issue.
To install the opencv-python package without the optional contrib modules into python3:
pip3 install opencv-python --user
To install the opencv-python package with the optional contrib modules into python3:
pip3 install opencv-contrib-python --user
Then to import the module:
import cv2
For both of these installations, their pypi sites state: 'This version does not support video related functionality for MacOS and Linux'.
The Pyimagesearch website by Adrian Rosebrock has a tutorial on how to download and compile opencv for Ubuntu with this functionality.
I use this command in the shell to install PIL:
easy_install PIL
then I run python and type this: import PIL. But I get this error:
Traceback (most recent call last):
File "<console>", line 1, in <module>
ImportError: No module named PIL
I've never had such problem, what do you think?
In shell, run:
pip install Pillow
Attention: PIL is deprecated, and pillow is the successor.
On some installs of PIL, you must do
import Image
instead of import PIL (PIL is in fact not always imported this way). Since import Image works for you, this means that you have in fact installed PIL.
Having a different name for the library and the Python module is unusual, but this is what was chosen for (some versions of) PIL.
You can get more information about how to use this module from the official tutorial.
PS: In fact, on some installs, import PIL does work, which adds to the confusion. This is confirmed by an example from the documentation, as #JanneKarila found out, and also by some more recent versions of the MacPorts PIL package (1.1.7).
On a different note, I can highly recommend the use of Pillow which is backwards compatible with PIL and is better maintained/will work on newer systems.
When that is installed you can do
import PIL
or
from PIL import Image
etc..
At first install Pillow with
pip install Pillow
or as follows
c:\Python35>python -m pip install Pillow
Then in python code you may call
from PIL import Image
"Pillow is a fork of PIL, the Python Imaging Library, which is no longer maintained. However, to maintain backwards compatibility, the old module name is used." From pillow installed, but "no module named pillow" - python2.7 - Windows 7 - python -m install pillow
This worked for me on Ubuntu 16.04:
sudo apt-get install python-imaging
I found this on Wikibooks after searching for about half an hour.
Sometimes I get this type of error running a Unitest in python. The solution is to uninstall and install the same package on your virtual environment.
Using this commands:
pip uninstall PIL
and
pip install PIL
If for any reason you get an error, add sudo at the beginning of the command and after hitting enter type your password.
you have to install Image and pillow with your python package.
type
python -m pip install image
or run command prompt (in windows), then navigate to the scripts folder
cd C:\Python27\Scripts
then run below command
pip install image
On windows 10 I managed to get there with:
cd "C:\Users\<your username>\AppData\Local\Programs\Python\Python37-32"
python -m pip install --upgrade pip <-- upgrading from 10.something to 19.2.2.
pip3 uninstall pillow
pip3 uninstall PIL
pip3 install image
after which in python (python 3.7 in my case) this works fine...
import PIL
from PIL import image
I used:
pip install Pillow
and pip installed PIL in Lib\site-packages. When I moved PIL to Lib everything worked fine. I'm on Windows 10.
Install Specific Version:
pip install Pillow
Upgrade Pillow
sudo pip3 install --upgrade Pillow
Getting Dependency Error in Window 10
Use code: easy_install instead of pip install
easy_install Pillow
Upgrade using easy install
sudo easy_install --upgrade Pillow
On OSX System to install Module:
Use code: brew install instead of pip install
brew install Pillow
Without Using Pip :
sudo apt-get install -y Pillow
On CentOS7 or Linux Fedora:
yum -y install Pillow
Or on Fedora try
sudo dnf install Pillow
Command if Homebrew screws up your path on macOS:
python -m pip install Pillow
For Python3 MacOs Homebrew screws
python3 -m pip install Pillow
Verify module from list MacOs
pip freeze | grep Pillow
For Execute on Anaconda as your python package manager
conda install -c anaconda Pillow
On windows, try checking the path to the location of the PIL library. On my system, I noticed the path was
\Python26\Lib\site-packages\pil instead of \Python26\Lib\site-packages\PIL
after renaming the pil folder to PIL, I was able to load the PIL module.
if you use anaconda:
conda install pillow
You will need to install Image and pillow with your python package.
Rest assured, the command line will take care of everything for you.
Hit
python -m pip install image
instead of PIL use Pillow it works
easy_install Pillow
or
pip install Pillow
The cleanest way to resolve this issue is by following below steps.
Step 1: Uninstall the PIL package.
pip uninstall PIL
Step 2: Install the Pillow using pip as shown below on windows operating systems. For other environments checkout the article No module named PIL
On Windows
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
Step 3: The most crucial class in the Python Imaging Library is the Image class, and you can import this as shown below.
from PIL import Image
im = Image.open("myimage.jpg")
If successful, this function returns an Image object. You can now use instance attributes to examine the file contents:
print(im.format, im.size, im.mode)
#Output: PPM (512, 512) RGB
I had the same issue on windows 10 and this worked for me:
pip install Pillow
pip(3) uninstall Pillow
pip(3) uninstall PIL
pip(3) install Pillow
This worked for me on Ubuntu 20.04:
pip install image
And in script:
import image
use pil instead of PIL
from pil import Image
On Windows, you need to download it and install the .exe
https://pypi.python.org/pypi/Pillow/2.7.0
I used conda-forge to install pillow version 5, and that seemed to work for me:
conda install --channel conda-forge pillow=5
the normal conda install pillow did NOT work for me.
I had the same problem and i fixed it by checking what version pip (pip3 --version) is, then realizing I'm typing python<uncorrect version> filename.py instead of python<correct version> filename.py
I used :
from pil import Image
instead of
from PIL import Image
and it worked for me fine
wish you bests
I had the same issue while importing PIL and further importing the ImageTk and Image modules. I also tried installing PIL directly through pip. but not success could be achieved. As in between it has been suggested that PIL has been deprectaed, thus, tried to install pillow through pip only. pillow was successfully installed, further, the PIL package was made under the path : python27/Lib/site-packages/.
Now both Image and ImageTk could be imported.
I recently installed Leap. I Tried openshot and it didn't start. So came here and found a suggestion to start from the Terminal to see if there were any error.
The error I had was error missing mlt. So I installed the python-mlt module from Yast and imported it, tried to start but next openshot said missing pil.
I Followed the Pillow suggestion to install because Yast couldn't find any pil and imported pil. That went ok but did not start and showed Error missing goocanvas.
The I installed goocanvas with Yast, imported it in python, and Openshot fired up !!
With a lot of errors in the terminal like missing Vimeoclient and lots of attributeerrors. Well, will see if it is of any influence working with it.
Python 3.8 on Windows 10. A combination of the answers worked for me. See below for a standalone working example. The commented out lines should be executed in the command line.
import requests
import matplotlib.pyplot as plt
# pip uninstall pillow
# pip uninstall PIL
# pip install image
from PIL import Image
url = "https://images.homedepot-static.com/productImages/007164ea-d47e-4f66-8d8c-fd9f621984a2/svn/architectural-mailboxes-house-letters-numbers-3585b-5-64_1000.jpg"
response = requests.get(url, stream=True)
img = Image.open(response.raw)
plt.imshow(img)
plt.show()
I had the same issue and tried many of the solutions listed above.
I then remembered that I have multiple versions of Python installed AND I use the PyCharm IDE (which is where I was getting this error message), so the solution in my case was:
In PyCharm:
go to File>Settings>Project>Python Interpreter
click "+" (install)
locate Pillow from the list and install it
Hope this helps anyone who may be in a similar situation!
I found an easier solution. Use a virtual environment.
pip install Pillow
from PIL import Image
This works for me on a macOS
According to the official websiteInstall Pillow, you may want to try this:
go to Terminal and run:
python3 -m pip install --upgrade pip
Then Run on
source ~/.bash_profile
You are probably missing the python headers to build pil. If you're using ubuntu or the likes it'll be something like
apt-get install python-dev
