Installing Clarisse

Scroll Prev Top Next More

Clarisse is a cross platform application and this chapter reviews all the different installation procedures related to each platform. Feel free to skip to your favored platform but first make sure your system meets Clarisse system requirements.

Minimum System Requirements

Clarisse has a modern multithreaded architecture and uses all the available system cores. The more cores your CPU has the faster the evaluation gets. At the time of this writing, since Clarisse only uses GPUs on some rare occasion, it doesn't require a high-end graphics card. For the latest minimum system requirements, please refer to https://www.isotropix.com/products/tech-specs

Installation Package

We don't provide an installer for Clarisse on all platforms. It comes either as an installer on Windows, a DMG iso on Mac OS X and as an archive file on Linux.

Windows

Launch the installer and follow the instructions.

Linux

Extract directly the archive content to any destination folder.

macOS

To install Clarisse, open the disk image and drag the Isotropix icon into your Applications folder.

Python in Clarisse

Unlike many other applications, Clarisse doesn't provide its own version of Python. Instead, Clarisse uses the one installed in the system. This way, there are no limitation and you can use any available Python extensions.

 

Python is installed by default on Linux and Mac OS X but not on Windows. Clarisse Windows installer provides the appropriate 64-bit installation of Python which gets installed by default.

Important

Clarisse only supports Python 2.X branch and not Python 3.X.

Specifying Python Location

By default, Clarisse should automatically locate where Python is installed on each supported platform. However, if the installation path has been customized or if Clarisse is running on a not officially supported distribution, you may have to manually specify Python Location.

 

You can either set Python environment variable PYTHONHOME to where Python is installed or modify the same variable in clarisse.env file. clarisse.env file can be found in the directory where Clarisse configuration is located. For more information on Clarisse configuration file please refer to Configuration and Environment section. Follow the exact same procedure if you wish to specify a custom Python build. If you have any issues regarding the installation of Python please refer to http://fixpython.isotropix.com
