How to Use OpenCV in PyCharm

OpenCV in PyCharm: In this post, I will share about how to use OpenCV in Pycharm. Pycharm is an incredible Python IDE. It is a product of JetBrains. It is available both as the community(free) edition and professional (paid) edition. I use the community edition of it and works great for my study purpose. Check out more about PyCharm on their official website.

OpenCV in PyCharm

1. Install Python3.X.

I assume you have installed Python on your PC or laptop already. If you have not done it yet, do it now. Download it from the official Python website, based on the OS on which your machine runs.

You can check out my post on OpenCV installation with Python by clicking here.

2. Install OpenCV using PIP
To install you will have to use pip tool which comes along with your Python installation.
To install OpenCV, run the following command:

3. Test Installation
Test whether the installation is successful or not by importing OpenCV to your Python shell.
1. Open your command prompt and enter python
2. Type the following press enter:

If no errors get echoed, your installation is successful!

Install Pycharm

If you have not install PyCharm, install it now. Download its installation file from its official website.

After the installation, do the following:
Create A Project
1. Create a new project

File > New Project

2. Name and Choose the project directory

3. Click on Create
3. Choose whether to open in new window or in existing Window and click OK

4. By default, PyCharm selects its virtual environment interpreter. To use OpenCV, select your own installation of Python. In your PyCharm click: File > Setting > Project: ‘Project name’ > Project Interpreter

5. Choose the Installation path of your python and click OK as shown above.

Test installation

Create a new file:
1. Select: File > New or use the shortcut combination: Alt + Insert
2. Choose Python File using arrow up and down keys
3. Enter a name and click OK
4. Import OpenCV and run the file.

If no errors get echoed, you can now use OpenCV with your PyCharm!

How to Install OpenCV (cv2) on PyCharm?

OpenCV is a framework for image processing and image recognition—among other things. It’s a super powerful tool in your data science and machine learning toolbelt! But how to install it in your PyCharm environment? This article will show you how!

Problem Formulation: Given a PyCharm project. How to install the OpenCV library in your project within a virtual environment or globally?

Here’s a solution that always works:

• Open File > Settings > Project from the PyCharm menu.
• Select your current project.
• Click the Python Interpreter tab within your project tab.
• Click the small + symbol to add a new library to the project.
• Now type in the library to be installed, in your example «opencv-python» without quotes, and click Install Package .
• Wait for the installation to terminate and close all popup windows.

Here’s the installation process as a short animated video—it works analogously for OpenCV, just type in “opencv-python” in the search field instead:

Make sure to type in “opencv-python” because there are many other packages that are not required but also contain the term “opencv” (False Positives):

Об установке opencv на pycharm и решении проблемы cv2 «cv2.» Без подсказки кода

1. Установка opencv под pycharm

Терминальный ввод под pycharm

Вы также можете скачать расширенную версию

pip install opencv-contrib-python

[Если вы не добавляли источник pip, проигнорируйте эту статью] Друзья, добавившие внутренний источник pip, не забудьте добавить его после командной строки (следующий пример — источник pip Tsinghua)

pip install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple

Если загрузка не удалась, это может быть проблема с сетью или проблема не в изменении источника pip.

Импортируйте каталог фреймворка после успешной установки

2. «cv2». Решение проблем без подсказки кода

1. Найдите соответствующий питонпапка site-packages

Введите следующую команду в командной строке

Затем перейдите в соответствующую папку, чтобы найти папку

2. Найдите _init_.py в папке cv2 в папке site-packages, откройте и измените его следующим образом

import sys import os import importlib os.environ["PATH"] += os.pathsep + os.path.dirname(os.path.realpath(__file__)) from .cv2 import * from .data import * # wildcard import above does not import "private" variables like __version__ # this makes them available globals().update(importlib.import_module('cv2.cv2').__dict__) 

Затем перезапустите pycharm ~~~

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

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.

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

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.
