I am running MacOS Mojave (10.14.6) and want to install python 3.7. Currently I have python 3.6 installed: $ python -V Python 3.6.9 There seems to be python 3.7 available: $ brew search python &. MacOS Mojave で Python 3.6 系をインストールする場合に，いつくかハマりどころがあったのでトラブルシューティングとして記事にしておきます。. Description Platform information (e.g. Ubuntu Linux 16.04): macOS Mojave 10.14 OS architecture (e.g. Amd64):amd64 pyenv version: 1.2.7 Python version: 3.7.0 & 2.7.15.

By platform, it is possible to switch the operation according to the OS and version.

This article describes the following contents:

• Get the system / OS name: platform.system()
• Get the system's release version: platform.release(), version()
• Get the OS, version, etc. together: platform.platform()
• Examples for each OS
  • macOS
  • Windows
  • Ubuntu
• Sample code that switches operation depending on the OS

See the following article for how to get the version of Python.

• Related:Check Python version from command line / in script

All sample code in the first half was run on macOS Mojave 10.14.2. Examples of results on Windows and Ubuntu are shown later. 2012 subaru outback service manual. OS-specific functions will also be described later.

Get the system / OS name: platform.system()

platform.system() returns the system / OS name as a string.

Get the system's release version: platform.release(), version()

platform.release() and platform.version() returns the system's release version as a string.

As shown in the example below, platform.release() returns simpler contents.

Get the OS, version, etc. together: platform.platform()

platform.platform() returns a string containing the OS name, version information, etc.

If terse is True, only minimal information is returned.

There is also an argument aliased.

The result is the same in the above example, but depending on the OS, alias is returned as the OS name.

If aliased is true, the function will use aliases for various platforms that report system names which differ from their common names, for example SunOS will be reported as Solaris.platform.platform() — Access to underlying platform's identifying data — Python 3.9.1 documentation

Examples for each OS

Examples of results run on macOS, Windows, and Ubuntu are shown bellow, along with OS-specific functions.

macOS

For macOS Mojave 10.14.2:

Same as the example shown above.

Note that the OS name is Darwin, not macOS or Mojave. See Wikipedia for the version number corresponding to the name in macOS.

platform.mac_ver() is a macOS-specific function that returns tuple (release, versioninfo, machine).

Windows

Desmume emulator controls mac. For Windows 10 Home:

Note that the return value 10 of platform.release() is a string, not an integer.

platform.win32_ver() is a Windows-specific function that returns tuple (release, version, csd, ptype). Logic midi instruments.

Ubuntu

For Ubuntu 18.04.1 LTS:

platform.linux_distribution() is a Unix-specific function that returns tuple (distname, version, id).

Note that this function was removed in Python 3.8. It is recommended to use the third party library distro instead.

Sample code that switches operation depending on the OS

For example, by using platform.system(), the operation can be switched depending on the OS.

Example of getting the creation date and time of a file:

In this example, the value of platform.system() is used to determine whether it is Windows or not, and then exception handling is used to switch the operation depending on whether the st_birthtime attribute exists.

See the following article for exception handling.

OpenCV released OpenCV-3.4.4 and OpenCV-4.0.0 on 20th November. There have been a lot of bug fixes and other changes in these versions. The release highlights are as follows:

Python 3 Mac Os Mojave 10.14

• OpenCV is now C++11 library and requires C++11-compliant compiler. Minimum required CMake version has been raised to 3.5.1.
• A lot of C API from OpenCV 1.x has been removed.
• Persistence (storing and loading structured data to/from XML, YAML or JSON) in the core module has been completely reimplemented in C++ and lost the C API as well.
• New module G-API has been added, it acts as an engine for very efficient graph-based image procesing pipelines.
• dnn module now includes experimental Vulkan backend and supports networks in ONNX format.
• The popular Kinect Fusion algorithm has been implemented and optimized for CPU and GPU (OpenCL)
  QR code detector and decoder have been added to the objdetect module.
• Very efficient and yet high-quality DIS dense optical flow algorithm has been moved from opencv_contrib to the video module.

Python 3 Mac Os Mojave Dmg

In this post, we will provide a bash script for installing OpenCV-4.0.0 (C++ and Python 3.7) on macOS – High Sierra and Mojave. We will also briefly study the script to understand what's going in it. Note that this script will install OpenCV in a local directory and not on the entire system. Let's jump in 🙂

1. Install XCode

Install XCode from App Store.

If XCode available on App Store is not compatible with your OS:

1. Find XCode version compatible to your OS from this table https://en.wikipedia.org/w/index.php?title=Xcode#Version_comparison_table
2. Go to this webpage https://developer.apple.com/download/more/
   • Login if you have apple developer account else create your account and login.
   • Search for xcode and download the version compatible to your OS.
3. Install XCode.
4. After installation open XCode, and accept xcode-build license when it asks.

2. Install OpenCV

Now that XCode has been installed, we will move on to OpenCV installation.

First, let's install Homebrew.

We will also add Homebrew to PATH.

Next we will install the requirements – Python 3, CMake and Qt 5.

We will also save current working directory in cwd variable and OpenCV version (master) in cvVersion.

Now, let's install the Python libraries and create the Python environment.

Next, let's clone the OpenCV github repositories.

Finally, we will use CMake Alien shooter 5. to build OpenCV.

And that's it! By now you should have OpenCV installed successfully in your system.

3. Test OpenCV Installation

3.1. OpenCV in Python

To use cv2 module in Python, we will first activate the Python environment.

3d printer slicer linux. Next, let's import the module and verify the OpenCV Version installed.

3.2. OpenCV in C++

To use OpenCV in C++, we can simply use CMakeLists.txt and specify the OpenCV_DIR variable. The format is as follows: Recording software online free no download.

Python 3 On Mac

Make sure that you replace OpenCV_Home_Dir with correct path. For example, in my case:

Once you have made your CMakeLists.txt, follow the steps given below.

This will generate your executable file in build directory.

Hope this script proves to be useful for you :). Stay tuned for more interesting stuff. In case of any queries, feel free to comment below and we will get back to you as soon as possible.
