If you have both versions of Python, install both Pip versions as well. The commands below use the apt utility as we are installing on Ubuntu for the purposes of this article. Install Pip (for Python 2) by running: sudo apt install python-pip. If you need Pip for Python 3, use the command: sudo apt install python3-pip. Pip install will by default do the install in this order: (1) build a wheel for fbprophet, (2) install package dependencies, (3) install fbprophet from the wheel. If pystan is not already installed, this is a problem: Pystan is needed to build the wheel in (1), but is not installed until (2).
$ sudo apt-get update $ sudo apt-get install python3.8 python3-pip Once the installation is complete, you can run Python 3.8 with the python3.8 command and pip with the pip3 command. Linux Mint and Ubuntu 17 and below: Python 3.8 isn’t in the Universe repository, so you need to get it from a Personal Package Archive (PPA). Doing it Right¶. Let’s install a real version of Python. Before installing Python, you’ll need to install GCC. GCC can be obtained by downloading Xcode, the smaller Command Line Tools (must have an Apple account) or the even smaller OSX-GCC-Installer package. Download Mac OS X 64-bit/32-bit x86-64/i386 Installer; Python 2.6.9 - Oct. No files for this release. Python 3.3.2 - May 15, 2013.
Mac OS X comes with Python 2.7 out of the box.
You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.
The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
Doing it Right¶
Let’s install a real version of Python.
Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.
Note
If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.
Note
If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running xcode-select--install on the terminal.
While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.
To install Homebrew, open Terminal oryour favorite OS X terminal emulator and run
The script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your PATH environment variable. You can do this by adding the followingline at the bottom of your ~/.profile file
If you have OS X 10.12 (Sierra) or older use this line instead
Now, we can install Python 3:
This will take a minute or two.
Pip¶
Homebrew installs pip pointing to the Homebrew’d Python 3 for you.
Working with Python 3¶
Install Pip For Python 3 Mac
At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.
will launch the Homebrew-installed Python 3 interpreter.
will launch the Homebrew-installed Python 2 interpreter (if any).
will launch the Homebrew-installed Python 3 interpreter.
If the Homebrew version of Python 2 is installed then pip2 will point to Python 2.If the Homebrew version of Python 3 is installed then pip will point to Python 3.
The rest of the guide will assume that python references Python 3.
Pipenv & Virtual Environments¶
The next step is to install Pipenv, so you can install dependencies and manage virtual environments.
A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.
For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.
So, onward! To the Pipenv & Virtual Environments docs!

PyQt is often not installed by default. The PyQt module can be used to create desktop applications with Python. In this article you’ll learn how to install the PyQt module.
Desktop applications made with PyQt are cross platform, they will work on Microsoft Windows, Apple Mac OS X and Linux computers (including Raspberry Pi).

How to install PyQt5 on Windows?
To install PyQt on Windows there are a few steps you need to take.
First use the installer from the qt-project website, from qt to install PyQt.
Next you want to install a Python version 3.3 or newer. Check the box to add all of the PyQt5 extras. It’s not necessary to compile everything from source, you can install all the required packages with the installer.
On Python >= 3.6, you can also try this command:
It should work without problems.
How to install PyQt5 on Mac OS X?
On Apple Mac OS X installation is a bit simpler. The first step to take is to install the Mac OS X binary. This installs the PyQt GUI library.
But to use it from Python, you also need Python module. This is where the tool brew comes in.
You can use brew to install pyqt (in the terminal):
How to install PyQt5 on Linux?
Python is often installed by default on Linux (in nearly all of the distributions including Ubuntu). But you want to make sure to use Python 3, because of all the features and ease of use. You can verify that you have the newest Python version with the command:

On Ubuntu Linux they sometimes include two versions of python, python3 and python. In that case use Python 3.
Once you have Python ready, the next step is to install PyQt.
This isn’t hard to do if you have some Linux experience. You can install PyQt your software package manager. Which package manager to use depends on which Linux distribution you are using.
On Ubuntu Linux / Debian Linux you can use the command:
For CentOS 7 use the command:
Install Pip For Python3 Macos
For RPM-based systems (Redhat-based)
