Prerequisite:Python Language Introduction
Before we start with how to install pip for Python on macOS, let’s first go through the basic introduction to Python. Python is a widely-used general-purpose, high-level programming language. Python is a programming language that lets you work quickly and integrate systems more efficiently.
PIP is a package management system used to install and manage software packages/libraries written in Python. These files are stored in a large “on-line repository” termed as Python Package Index (PyPI).
The best working solution I've found so far was installing all open source packages via Anaconda (GDAL,Shapely,Fiona, Numpy etc.) and then just using the versions of Python that come with QGIS/Arc. However, with this method I can't combine Qgis.core functions and Open source stuff which is what I want to do. Getting started with Anaconda¶. Anaconda Individual Edition contains conda and Anaconda Navigator, as well as Python and hundreds of scientific packages.When you installed Anaconda, you installed all these too. Conda works on your command line interface such as Anaconda Prompt on Windows and terminal on macOS and Linux.
pip uses PyPI as the default source for packages and their dependencies. So whenever you type:
pip will look for that package on PyPI and if found, it will download and install the package on your local system.
Download and Install pip:
pip can be downloaded and installed using command-line by going through the following steps:
- Download the get-pip.py file and store it in the same directory as python is installed.
or
Use the following command to download pip directly, - Now execute the downloaded file using below command
and wait through the installation process.
- Voila! pip is now installed on your system.
Verification of the Installation process:
One can easily verify if the pip has been installed correctly by performing a version check on the same. Just go to the command line and execute the following command:

How to start doing GIS with Python on your own computer?
Well, first you need to install Python and necessary Python modules that are used to perform various GIS-tasks. The purpose of this page is to help youout installing Python and all those modules into your own computer. Even though it is possible to install Python from their homepage,we highly recommend usingAnaconda which is an open source distribution of the Python and R programminglanguages for large-scale data processing, predictive analytics, and scientific computing, that aims to simplify package management and deployment. In short,it makes life much easier when installing new tools on your Python to play with.
Install Python + GIS on Windows¶
Following steps have been tested to work on Windows 7 and 10 with Anaconda3 64 bit, using conda v4.3.29 (30th October 2017).
Download Anaconda installer (64 bit) for Windows.
Install Anaconda to your computer by double clicking the installer and install it into a directory you want (needs admin rights).Install it to all users and use default settings.
Note
Note for University of Helsinki workers: you need to set the installation location as C:HYapp so that it can be used easily by anyone without the need topass admin credentials all the time. If you don’t have C:HYapp -folder, create one with admin rights.
Test that the Anaconda´s package manage called conda works by opening a command prompt as a admin userand running command conda--version.
Install GIS related packages with conda (and pip) by running in command prompt following commands (in the same order as they are listed):

Test that everything works¶
You can test that the installations have worked by running following commands in your IPython console (comes with mini-conda).
If you don’t receive any errors, everything should be working!
Install Python + GIS on Linux / Mac¶
The following have been tested on Ubuntu 16.04. Might work also on Mac (not tested yet).
How To Install Qgis
Install Anaconda 3 and add it to system path
Install Python packages
Install GIS related packages with conda (and pip) by running in command prompt following commands (in the same order as they are listed):
How to find out which conda -command to use when installing a package?¶
The easiest way¶
The first thing to try when installing a new module X is to run in a command prompt (as admin) following command (here we try to install a hypotheticalmodule called X)

In most cases this approach works but sometimes you get errors like (example when installing a module called shapely):
Okey, so conda couldn’t find the shapely module from the typical channel it uses for downloading the module.
Alternative way to install if typical doesn’t work¶
Qgis Latest Version
How to find a way to install a module if it cannot be installed on a typical way?Well, the answer is the same is in many other cases nowadays, Google it!
Let’s find our way to install the Shapely module by typing following query to Google:
Okey, we have different pages showing how to install Shapely using conda package manager.
Which one of them is the correct one to use?
We need to check the operating system banners and if you find a logo of the operating system of your computer,that is the one to use! Thus, in our case the first page that Google gives does not work in Windows but the second one does, as it has Windows logo on it:

From here we can get the correct installation command for conda and it works!

You can follow these steps similarly for all of the other Python modules that you are interested to install.
