How to get started

Install Python

In order to make use of the PyMedPhys library, you’ll need Python installed on your workstation. On Windows we recommend that you install the Anaconda Python distribution. Download the latest Anaconda Python 3 (not 2) version from here.

Note

When installing Anaconda make sure to install it for your user only, and tick the option “add to path”.

On Linux or MacOS we recommend not using your system Python and instead managing your Python installation using something like pyenv.

Installing PyMedPhys

Once you have Python you can now install PyMedPhys via pip by typing the following in a terminal or command prompt:

pip install pymedphys

You may need to open and close your terminal if you have only just installed Python.

A minimal installation

The greater majority of PyMedPhys’ dependencies are actually optional. They are only installed for simplicity for new users. You may however choose to install PyMedPhys without these dependencies by running:

pip install pymedphys --no-deps

Installation on MacOS

One of PyMedPhys’ dependencies is pymssql. Before installing PyMedPhys on MacOS you need first install both freetds via homebrew and Cython. To do this follow the steps below:

To install homebrew (as described at <https://brew.sh/>):

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then to install freetds open a new shell, then run:

brew install freetds

And lastly to install cython run:

pip install cython

Then you will be able to successfully run:

pip install pymedphys

Installing the Bleeding Edge version of PyMedPhys

If you wish to be able to contribute to PyMedPhys itself you are going to want to instead install PyMedPhys from the master branch on GitHub <https://github.com/pymedphys/pymedphys>. To achieve this follow the OS specific instructions within the contributor tutorials:
