In computing, a module is a unit of software that is designed to be independent, interchangeable, and contain everything necessary to provide some desired functionality. | |||
<ref>[https://en.wikipedia.org/wiki/Modular_programming Wikipedia, "Modular programming"]</ref> | |||
The term "module" may sometimes have a more specific meaning depending on context. | |||
This page describes a few types of modules and cites their corresponding documentation pages. | |||
=== | == Disambiguation == | ||
=== Lmod modules === | |||
Also called "environment modules", Lmod modules are used to alter your (shell) environment so as to enable you to use a particular software package, | |||
or to use a non-default version of certain common software packages such as compilers. See [[Using modules]]. | |||
=== Python modules === | |||
In Python, a module is file of code (usually Python code) which can be loaded with the <code>import ...</code> or <code>from ... import ...</code> statements to provide functionality. A Python package is a collection of Python modules; the terms "package" and "module" are frequently interchanged in casual use. | |||
<ref>[https://www.tutorialspoint.com/What-is-the-difference-between-a-python-module-and-a-python-package Tutorialspoint.com, "What is the difference between a python module and a python package?"]</ref> | |||
Certain frequently-used Python modules such as "Numpy" can be imported if you first load the <code>scipy-stack</code> Lmod module at the shell level. | |||
See [[Python#SciPy_stack|SciPy stack]] for details. | |||
Compute Canada maintains a large collection of [[Python#Available_wheels|Python "wheels"]]. | |||
These are modules which are pre-compiled to be compatible with the [[Standard software environments]]. | |||
Before importing modules from the Compute Canada wheels, you should create a [[Python#Creating_and_using_a_virtual_environment|virtual environment]]. | |||
Python modules which are in neither the <code>scipy-stack</code> Lmod module or our wheels collection can be installed from the internet | |||
as described at [[Installing packages|Python#Installing_packages]]. | |||
