The hyperspy-bundle is a program, which installs a python distribution including hyperspy and other relevant scientific software and libraries for the analysis of multidimensional datasets. It aims at making the installation of a python distribution very easy and integrating with existing established practices in the scientific research community. If you are brand new to python, this is the easiest way to install HyperSpy.
Older releases (including HyperSpy <= 1.3) are available in HyperSpy's GitHub repository.
