Как установить opencv python pycharm
If you love working on image processing and video analysis using python then you have come to the right place. Python is one of the key languages which is used to process videos and images.
Requirements for OpenCV:
- 32- or a 64-bit computer.
- Windows, macOS or Linux.
- Python 2.7, 3.4, 3.5 or 3.6.
PyCharm
PyCharm is a cross-platform IDE used in computer programming specifically for Python. The platform developed by JetBrains is mainly used in code analysis, graphical debugger etc… It supports web development with Django as well as Data Science with Anaconda.
Official Website: https://www.jetbrains.com/pycharm/
OpenCV
OpenCV (Open Source Computer Vision) is a computer vision library that contains various functions to perform operations on pictures or videos. It was initially built by Intel but later managed by Willow Garag, presently it is managed by Itseez. It is a cross-platform library which available for programming languages apart from python.
Method 1: Steps to import OpenCV on PyCharm (Using Terminal):
1) Go to the terminal option at the bottom of the IDE window.
2) The pip (package manager) can also be used to download and install OpenCV. To install OpenCV, just type the following command:
How to install OpenCV on Windows and enable it for PyCharm without using the package manager
I am trying to install and use OpenCV library for python development. I want to use it for PyCharm IDE. I am trying to do it without the package manager.
The environment is a windows 64 bit architecture. For Python I am using Python 2.7.10.
I have already included the OpenCV directory in the system path.
I am using python 2.7.10 interpreter for PyCharm and have installed the pip and numpy packages.
How to Install OpenCV using pip : 3 Methods
I have seen many python programmers have faced difficulties while installing OpenCV. They are getting some errors like no module named cv2 when they import or use OpenCV code. Therefore I have come here with a “how-to ” tutorial on “How to Install OpenCV using pip“. In this entire post, you will know the various methods to install OpenCV using pip.
Method 1: Installing pre-built OpenCV package using pip
In this method, I will show you how you can install OpenCV directly using the pip command. There is an unofficial pre-built OpenCV package for Python that allows you to do so.
Open your command prompt and type the following command. You should also remember that the pip command differs for different python versions. Therefore make sure you check the python version using the following command.
In my case, it is 3.7.4. However, I am showing you how to install it on both python versions, python 2. xx, and python 3. xx. That’s why use according to it.
For python 2. xx version
For python 3. xx version
Installing Pre-built OpenCV python module using pip
You can see I have already installed OpenCV on my computer. Otherwise, it will start downloading the package and install OpenCV.
Method 2: Install Opencv using pip on the whl file
The other method to install OpenCV in your system is using the .whl file. The whl file is a package saved in the wheel format that is used for package distribution in python. But before installing using this method make sure you have already installed numpy. Go to the repository website and search for the OpenCV package. There you will different versions of the OpenCV packages. Download the wheel file according to your system. My OS is windows, so I am downloading the win32 version.
OpenCV Version repository
After downloading it, go to that directory using the command prompt and type the pip3 command to install OpenCV.
It will compile the wheel file and install the OpenCV package in your system.
Method 3: Installing OpenCV using pip in Pycharm
Sometimes we are unable to install the OpenCV package inside the Pycharm directly. Then the pip command will help you. Just go to the terminal inside the PyCharm and type the following command. It will install the OpenCV python package.
pip3 install opencv-python Installing OpenCV using pip inside the Pycharm
Conclusion
OpenCV is a library for making the computer vision task very easy. It allows you to manipulate images and videos efficiently. But many beginners are unable to install it in their system. These are the methods I have aggregated for you that will be very helpful for you in installing OpenCV. Even if you are unable to install it then you can contact us for more help.
