Installation

There are two ways of using MatFlow:

• The MatFlow command-line interface (CLI)

• The MatFlow Python package

Both of these options allow workflows to be designed and executed. The MatFlow CLI is recommended for beginners and strongly recommended if you want to run MatFlow on a cluster. The Python package allows workflows to be designed and explored via the Python API and is recommended for users comfortable working with Python. If you are interested in contributing to the development of MatFlow, the Python package is the place to start.

The CLI and the Python package can be used simultaneously.

MatFlow CLI

The MatFlow CLI can be installed on Linux, macOS, and Windows through a terminal or shell prompt:

Linux/macOS

Open a terminal, paste the command shown below and press enter.

(touch tmp.sh && curl -fsSL https://raw.githubusercontent.com/hpcflow/install-scripts/main/src/install-matflow.sh > tmp.sh && bash tmp.sh --prerelease --path --univlink) ; rm tmp.sh

Windows

Open a Powershell terminal, paste the command shown below and press enter.

& $([scriptblock]::Create((New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/hpcflow/install-scripts/main/src/install-matflow.ps1'))) -PreRelease -UnivLink

What does this script do?

The above command downloads a script from the MatFlow GitHub repository and runs it. The script does the following:

1. It downloads the latest prerelease version of MatFlow zip archived in a single folder.

2. The archive is extracted and the folder placed in an accessible location. The location depends on the operating system. In Linux it is /.local/share/matflow. In macOS it is ~/Library/Application Support/matflow. In Windows it is Username\AppData\Local\matflow.

3. A symbolic link (Linux/macOS) or an alias pointing to the file is created. This allows MatFlow to be run by entering a simple command.

4. A command is added to .bashrc/.zshrc (linux/macOS) or the Powershell profile (Windows) that allows MatFlow to be run from any folder.

If the script detects that the version of MatFlow it is trying to install is already there, it will stop running and exit.

Hint

If you are installing MatFlow on an HPC resource, check that you can connect to the internet first. You might need to load a proxy module, for example.

MatFlow Python package

Using pip

Use pip to install the Python package from PyPI:

pip install matflow-new=="0.3.0a138"
