I'm trying to install Pygame. I am running Windows 7 with Enthought Python Distribution. I successfully installed pip, but when I try to install Pygame using pip, I get the following error:
"Could not install requirement Pygame because of HTTP error HTTP error
400: Bad request for URL ..."
I can't find anything about this issue with a Google search, but I did find another Stack Overflow question that prompted the asker to use the following command:
pip install hg+http://bitbucket.org/pygame/pygame
This gave me the following error:
Cannot find command hg
I'm not sure what else to do, as everything I find with a Google search is for Mac, so I don't know how well I can follow those instructions on Windows.
Steps to install PyGame using pip
Install build dependencies (on linux):
sudo apt-get build-dep python-pygame
Install mercurial to use hg (on linux):
sudo apt-get install mercurial
On Windows you can use the installer: Download
Use pip to install PyGame:
pip install hg+http://bitbucket.org/pygame/pygame
If the above gives freetype-config: not found error (on Linux), then try sudo apt-get install libfreetype6-dev and then repeat 3.
Alternative way:
# Grab source
hg clone https://bitbucket.org/pygame/pygame
# Finally build and install
cd pygame
python setup.py build
sudo python setup.py install
Try doing this:
sudo apt-get install mercurial
sudo pip install hg+http://bitbucket.org/pygame/pygame
An update to this may be required, as it stands in version 1.9.1 it should simply install using:
pip install pygame
However, it look like there is a bug with their pypi repository, see:
https://bitbucket.org/pygame/pygame/issues/59/pygame-has-no-pypi-page-and-cant-be
So, if you want the most recent release, you have to point directly at the ftp file ala:
pip install http://www.pygame.org/ftp/pygame-1.9.1release.tar.gz
I suppose this will be fixed in the 1.9.2 release but for now this works.
I would note that the answer supplied by Pratyush works as well, but requires the user to install mercurial if they don't have it and downloads the trunk version, so really, not ideal unless you absolutely need it.
Caveat: I'm not familiar with the Enthought Distribution, so this might not help.
As you're trying to install on Windows, if you don't want to have to mess around with C compilers, there are pre-built binary wheels for pygame here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pygame
Select a package appropriate to you python version[0] and Windows architecture [1]. Download to C:\Users\User\Download\pip install E:\env\pygame-1.9.2a0-cp27-none-win_amd64.whl and install with pip install E:\env\pygame-1.9.2a0-cp27-none-win_amd64.whl
Mercurial binaries can be found on the same page, if you would like to install from source. This method would mean compiling pygame from source, for which you probably want to use this compiler package.
[0] python --version
[1] powershell "gwmi win32_operatingsystem | select osarchitecture"
The command below worked for me on Mac OS X El Capitan:
pip3 install pygame
Install on MAC:
brew install homebrew/python/pygame
Just
sudo pip install pygame
worked for me
Had this issue on macOS Sierra, where apt-get doesn't work.
Managed to solve the issue through the following steps:
First I had to install the Mercurial via Brew:
brew install mercurial
Then, I had to install Pygame dependencies:
brew install sdl sdl_image sdl_mixer sdl_ttf smpeg portmidi
Finally I used pip3 to install Pygame:
pip3 install pygame
Hope this helps!
Try
python3 -m pip install -U pygame --user
This worked twice for me on windows 7 and windows 10
The most current, the best way to install pygame is always available at:
https://www.pygame.org/wiki/GettingStarted
How to use pip depends on the operating system. So unless you have always updated and tested answers for 15 different operating systems then just send people to that page. All answers to this question are wrong for various different operating systems.
Currently, for windows, this is the way to install it in the cmd prompt. (If you already have pip installed, and people know what pip is... best just send people to the GettingStarted page).
py -m pip install pygame --user
I did use these instructions here from the official site.
But i had to change the python3 part of the command to just py.
Try: python -m pip install pygame
Or: py -m pip install pygame
Try pip install pygame or pip3 install pygame.
These should work for you.
If this does not work for you put -m before pip and python before
-m.
If putting -m does not work try reinstalling python
If you are working on windows, the command below should work fine
pip install pygame
If you are working on Linux, the command below should work fine
sudo apt-get install python-pygame
Type this in command prompt
pip install pygame
or
py -m pip install pygame
WINDOWS
If you are on a windows 10 device then you should use this command but first make sure you have Python installed from https://python.org, if you do run this in command prompt
py --version
and then whatever version it says you have (which you downloaded) keep it in mind we will use it later for now just incase try to upgrade pip incase you are on a outdated version I will be using 3.9 for the version for the rest of this as an example
py -3.9 -m pip --upgrade pip
After that if you have it already satisfied or it upgraded run this command in command prompt
py -3.9 -m pip install pygame
And wait for it to download
And to make sure it worked run this
py -3.9 -m pygame --version
If it shows the version you downloaded it!
MacOS
For MacOS do the same but then run this command to install it
python3 -m pip install -U pygame --user
or if it wont work
py -3.9 -m pip install -U pygame --user ( or just pip3 )
to see if it worked run this
python3 -m pygame.examples.aliens
or
py -3.9 -m pygame.examples.aliens
I hope this helped
I have never used Enthought distribution, but you could try to use Anaconda distribution which is also great too.
Anaconda Distribution (Any OS):
From the docs:
Update conda to the current version.
Type the following:
conda update conda
If a newer version of conda is available, type y to update:
Proceed ([y]/n)? y
Check to see if a package you have not installed named
“pygame” is available from the Anaconda repository (must be
connected to the Internet):
conda search pygame
Conda displays a list of all packages with
that name on the Anaconda repository, so we know it is available.
Install this package into the current environment:
conda install pygame
Check to see if the newly installed
program is in this environment:
conda list
Install on Windows (both python 2.7 and 3.7):
pip install pygame
Install on raspberry pi:
sudo pip3 install pygame (python 3.7)
sudo pip install pygame (python 2.7)
I think if you go to Command Prompt and type
py -m pip install pygame
that's what works for me
Here is a way: sudo install pygame Rasberry pi has it ready-installed
Install python 3.8 from python.org
Then install pygame (2.0) like this
pip install pygame==2.0.0.dev10
Make sure script path is registered in environment variables,
Make sure the python path is registered in environment variables,
also you dont have to enter entire url just write like this(windows only I dont use mac)
pip
pip install pygame
hope it work
command to install pygame is:
pip install pygame
run it in command prompt
Try doing this for python3:
python3 -m pip install pygame==1.9.6
and this for python2:
python -m pip install pygame==1.9.6
You don't have to type in the entire url. Just simply go to command prompt (windows) or terminal (mac) and then type in:
[windows] pip install pygame
[mac] python -m install pygame
hopefully that works :)
To install pygame with pip, use the following commands in the Command Prompt on Windows.
py -m pip download pygame
then...
py -m pip install pygame
You only have to do the download pygame one if it doesn't work when you use the install pygame command by itself.
You type py -m to show that it is using the module pip, which can be accessed through the command prompt.
This is for Windows. For Mac OS, use python -m pip install pygame
I know that there are already lot's of answers, but if you want to download a specific version of pygame, you can use pip:
pip install pygame==1.9.6
Pygame 1.9.6 is the latest version at the time of writing.
Pygame tells you how to install it here, in my personal experience this is what I do on windows to install it, open up command prompt and type python -m pip install pygame if that fails, check if you have more than one version of python installed if so you need to specify what version for example python3.5 -m pip install pygame the reason we do this from command prompt is that in the Python shell it doesn't understand what pip install is just to break it down a little python -m calls a python module in this case we want pip the next two arguments are what we want pip to do and what module/addon we want the action to be applied too
I'm trying to install pythonnet in order to use clr module. But it doesn't work ...
Here is my command "Conda install -c pythonnet pythonnet"
and here as the results :
enter image description here
enter image description here
I tried several time to reinstall but i still have the same problem ...
Thank you and have a nice day !
if conda install does not work, try pip install pythonnet. Better, python -m pip install pythonnet. It is ok to use pip within conda. use conda as your first choice whenever you can. pip is the 2nd choice.
Note that pythonnet as of today still only support up to 3.7, according to https://pypi.org/project/pythonnet/, although 3.8.1 according to https://github.com/pythonnet/pythonnet
I need to install cv2 for a script that has been written for me. I tried pip install cv2 and pip install open_cv and got the same problem - a warning message from dist.py and complains about zlib being not found. No cv2 installed. I also tried pyopenvc and pip install opencv-python.
So, I went to the opencv site and downloaded the relevant exe. Ran it - generated a heap of subdirectories and a make file and stuff.
What do I do now?
Install opencv-python (which is an unofficial pre-built OpenCV package for Python) by issuing the following command:
pip install opencv-python
run the following command by creating a virtual enviroment using python 3 and run
pip3 install opencv-python
to check it has installed correctly run
python3 -c "import cv2"
In pip package management, there are 4 different OpenCV packages all using the same namespace, cv2. Although they are not officially supported by OpenCV.org, they are commonly used in developers' community. You could install any of them using the following command:
pip install PACKAGE_NAME
where PACKAGE_NAME can be
opencv-python (only contains main modules)
opencv-contrib-python (contains both main and contrib modules)
opencv-python-headless (same as opencv-python but without GUI functionality)
opencv-contrib-python-headless (same as opencv-contrib-python but without GUI functionality)
You should only install one of them depending on your needs. If you accidentally installed multiple of them in the same environment, you can remove them using pip uninstall before installing the correct one again.
For more details, you can refer to the project description of OpenCV on Wheels.
As of 2021, all of these 4 packages are official OpenCV projects. Source: OpenCV Website.
To Install the Current Latest version of OpenCV then use the below commands:
Use this Command:
pip install --upgrade opencv-python
If you're facing problem in above command then try this :
pip install --upgrade opencv-contrib-python
To check the version of installed OpenCV:
import cv2
print(cv2.__version__)
Simply use this for the so far latest version 4.1.0.
pip install opencv-contrib-python==4.1.0.25
For the default version use this:
pip install opencv-contrib-python
If you have a new Raspberry Pi and want to install OpenCV then this tutorial would be a good choice.
For Ubuntu/Linux users:
sudo apt install python3-opencv
As of 10/22/2019, I think the best answer is simply
conda install opencv
It appears opencv is now in the main Anaconda channel.
To see which packages (including opencv) are in the main Anaconda channel go to Anaconda Package Lists and follow the link corresponding to your python version and os version.
Everybody struggles initially while installing OpenCV. OpenCV requires a lot of dependencies in the backend. The best way to start with OpenCV is, install it in a virtual environment. I suggest that you use the Python Anaconda distribution and create a virtual environment using it. Then inside the virtual environment, you can install OpenCV using this command:
conda install -c conda-forge opencv
Please follow the command:
pip install opencv-python
then if you want to use:
import cv2
If it's not worked due to any update, please follow the documentation
Make a virtual enviroment using python3
virtualenv env_name --python="python3"
and run the following command
pip3 install opencv-python
to check it has installed correctly run
python3 -c "import cv2"
To install open_cv you can go to this website or do this,
pip install opencv-contrib-python --upgrade
pip install opencv-python
You can test it by:
C:\> python
>>> import cv2
>>> print(cv2.__version__)
'4.5.1' # your version may be a newer one
You can install opencv the normal way:
pip install opencv-python
If you are getting errors, you can do this:
pip install opencv-python-headless
Open anaconda command prompt and type in below command.
conda install -c conda-forge opencv
Once the 'Solving environment' is done. It will ask to download dependencies. Type 'y'.
It will install all the dependencies and then you are ready to code.
I recommend this for Python 3: Please install it this way with pip
pip3 install opencv-python
This will download and install the latest version of OpenCV.
You could try using below command-
pip install opencv-contrib-python
It will basically download the compatible version. If this command fails, you could upgrade you pip using below command-
python -m pip install –upgrade pip
If you need a pictorial guide, head over to Simple Steps to Install OpenCV in Windows
You can also try installing OpenCV from prebuilt binaries from the official OpenCV site.
->pip install opencv-python you can use this.
But if this code does not working then you can check python version on cmd and anaconda because they are different. So you type command in anaconda prompt and cmd, it will work. You can check this -> pip list
Open terminal
Run the following command
pip install --trusted-host=pypi.org --trusted-host=files.pythonhosted.org opencv-python.
Hope it will work.
Installing cv2 or opencv-python using pip is sometimes a problem. I was having the same problem of installing cv2 with pip. The installation wasn't a problem the problem was to import cv2 after installation. I was getting an Import Error so to fix this i import main from pip to install opencv-python. Try to run the following code in your python file then opencv-python will be installed
from pip._internal import main as install
try:
import cv2
except ImportError as e:
install(["install", "opencv-python"])
finally:
pass
I hope this will help someone
As a reference it might help someone... On Debian system I hard to do the following:
apt-get install -y libsm6 libxext6 libxrender-dev
pip3 install opencv-python
python3 -c "import cv2"
On Ubuntu you can install it for the system Python with
sudo apt install python3-opencv
if you are using Pycharm navigate settings > Project:name > Project interpreter just search the module by name(in this case OpenCV-python) and install it. worked for me
In case you use aarch64 platform with ARM64 cpu - and/or docker
On a development board on ARM64, no python-opencv version were found at all
version: NONE.
I've had to build from source. This allowed to include CUDA support.
In my case it was already available on the board but it wasn't found on the development environment.
If compiling from source is out of reach, there are Dockers
Of course compiling will take some time (few hours on ARM core), but it is worthy process to know as most open source tools can be built this way in case of issues.
I've had this problem in Google Colab, It only worked with this specific package version.
!pip install "opencv-python-headless<4.3"
There are two options-
pip install cv2
or
pip install opencv-python
Hope it helps.
I've been trying to install both OpenCV and cv2 from both Pycharm and from the terminal as suggested using:
pip install --user opencv
pip install --user cv2
but I'm getting the following error for them:
Collecting opencv
Could not find a version that satisfies the requirement opencv (from versions: )
No matching distribution found for opencv
and
Collecting cv2
Could not find a version that satisfies the requirement cv2 (from versions: )
No matching distribution found for cv2
How can I fix these and install the packages properly? I'm using python 3.4.
You are getting those errors because opencv and cv2 are not the python package names.
These are both included as part of the opencv-python package available to install from pip.
If you are using python 2 you can install with pip:
pip install opencv-python
Or use the equivilent for python 3:
pip3 install opencv-python
After running the appropriate pip command your package should be available to use from python.
This the correct command that you need to install opencv
pip install opencv-python
if you get any error when you are trying to install the "opencv-python" package in pycharm, make sure that you have added your python path to 'System Variables' section of Environment variables in Windows.
And also check whether you have configured a valid interpreter for your project
I ran into the same problem. One issue might be OpenCV is created for Python 2.7, not 3 (not all python 2.7 libraries will work in python 3 or greater). I also don't believe you can download OpenCV directly through PyCharm's package installer. I have found luck following the instructions: OpenCV Python. Specifically:
Downloading and installing OpenCV from SourceForge
Copying the cv2.pyd file from the download (opencv\build\python\2.7\x64) into Python's site-packages folder (something like: C:\Python27\Lib\site-packages)
In PyCharm, open the python Console (Tools>Python Console) and type:import cv2, and assuming no errors print cv2.__version__
Alternatively, I have had luck using this package opencv-python, which you can straightforwardly install using pip with pip install opencv-python
Good luck!
python3.6 -m pip install opencv-python
will install cv2 in python3.6 branch
On Windows:
!pip install opencv-python
Try this. I am using Jupyter notebook (OS: Ubuntu 16.04 LTS on Google Cloud Platform + on Windows). Executed following command in the Jupyter notebook to install opencv:
!pip install opencv-contrib-python #working on both Windows and Ubuntu
After successful installation you will get following message:
Successfully installed opencv-contrib-python-4.1.0.25
Now restart the kernel and try to import opencv as:
import cv2
The same command can be used to installed opencv on Windows as well.
SOLUTION 2: try following commands to install opencv:
For Ubuntu:
Run following command from terminal:
sudo apt-get install libsm6 libxrender1 libfontconfig1
Restart Jupyter notebook kernel and execute following command:
!pip install opencv-contrib-python
NOTE: You can run all the above commands from the terminal as well without using '!'.
Keep it simple and just run.
pip install opencv-python
This is the simplest way of installing opencv.
If you still face issue, create a virtual environment and try installing opencv.
I rather use Virtualenv to install such packages rather than the entire system, saves time and effort rather than building from source.
I use virtualenvwrapper
Windows user can download
pip install virtualenvwrapper-win
https://pypi.org/project/virtualenvwrapper-win/
Linux follow
pip install opencv-python
opencv-python
If processing a video is required
pip install opencv-contrib-python
opencv-contrib-python
If you do not need GUI in Opencv
pip install opencv-contrib-python-headless
opencv-contrib-python-headless
here is a tutorial that worked for me without any problem.
Copied from the site above the important part:
Download the OpenCV version corresponding to your Python installation
from here. In my case, I’ve used
opencv_python-3.1.0-cp35-cp35m-win32.whl.
Now, open a cmd window like before. You can open this directly in your
Downloads folder if you SHIFT and right click inside it. The idea is
to open a cmd window where you’ve downloaded the above [...] file. Use
the [...] command to install [...] OpenCV:
1 pip install "opencv_python-3.1.0-cp35-cp35m-win32.whl"
Additional note: don't forget to change the name of the downloaded file in the command you use.
Apparently by installing opencv, you'll have access to cv2 too.
Installing opencv is not that direct.
You need to pre-install some packages first.
I would not recommend the unofficial package opencv-python. Does not work properly in macos and ubuntu (see this post). No idea about windows.
There are many webs explaining how to install opencv and all required packages.
For example this one.
The problem of trying to install opencv several times is that you need to uninstall completely before attempting again, or you might end having many errors.
you must install opencv-python
pip/pip3 install opencv-python
if you try import opencv-python, receive error.
Fix this error, use the import cv2
How about try some different mirrors?
If you are in China, I highly recommend you try:
sudo pip install --index https://pypi.mirrors.ustc.edu.cn/simple/ opencv-contrib-python
If not, just replace the url address to some other mirrors you like!
Good luck.
this will help you
pip3 install opencv-python
this is the snippet of successful installation
First step:
pip uninstall numpy
pip uninstall opencv-python
Second step:
pip install numpy
pip install opencv-python
I had the same problem. Here are the steps for Windows 10 users.
Open CMD: win+r then type cmd. Now,
Type pip install virtualenv
Create a Virtual Environment, Type virtualenv testopencv
Get Inside testopencv, Type cd testopencv
Activate the Virtual Environment, Type .\Scripts\activate
Now Install Opencv, Type pip install opencv-contrib-python --upgrade
Let's test Opencv, Type Python then import cv2 hit enter then type print(cv2.__version__) to check if its installed
Now, open a new cmd, win + r then type cmd, repeat step 6. If it gives you an error.
Go inside the testopencv folder, inside lib. Copy everything, go to your python directory, inside lib folder paste it and skip that are already present.
Again open a new cmd, repeat Step 6.
Hope it helps.
In win, download the py based latest numpy and Opencv from Unofficial Windows Binaries for Python Extension Packages and pip install its source in cmd. Later copy site-package folder from main py lib to venv lib.
In jetso nano this work for me.
$ git clone https://github.com/JetsonHacksNano/buildOpenCV
$ cd buildOpenCV
When I was facing this issue I used to install OpenCV in pycharm installed package panel where we can find under the settings tab. Search "OpenCV-python" and install it in the installed package panel of right interpreter.
First run from cmd
pip --version
to make sure that you have the updated version installed.
Then run
pip install opencv-python
Go through with this link: https://learnopencv.com/install-opencv-4-on-raspberry-pi/
you can install OpenCV perfectly with out any error. but the problem was it will take lot of time to install.
I had used pi3 model B+ with 32GB class10 SD card for me it took more than 12 hours for complete installation.
If you still find any error to install open-cv in your mac, try this:
opencv-python==4.2.0.34
This worked for me.
I don't want to mess up with Xcode and stuff like that. I've tried a few command line installations but nothing seemed to work smoothly and I can't figure it out. Is there a way for someone who doesn't know a lot about programming to install Pillow? (Bonus points if you can give me an installation file that just does it all for you, that's the way I've done it on my Windows).
Thank you!
sudo easy_install pip
will install pip for you and then
pip install Pillow
will install Pillow as #dqiu mentioned.
You can use Python's package manager pip.
pip install Pillow should do the trick to install it.
You can see all the other ways on the webpage for Pillow.
You should follow these steps, as detailed in the pip documentation:
Download get-pip.py. Right click on the link and download the file.
Open your Terminal
Type sudo python ~/Downloads/get-pip.py (if the file is in the default Downloads folder). Or type the full path to the file.
You will be prompted for a password, type your normal user password.
This script will install pip and setuptools (if its not already installed). Now you can proceed to install Pillow and other packages:
pip install Pillow
If you run into problems, have a look at Installing Pillow/PIL on Mavericks.
virtualenv worked for me!
sudo pip install virtualenv
virtualenv python_script && cd !$
. /activate/bin
pip install Pillow
