Spack will be used to manage open source software packages on Fugaku.
Fugaku users can easily use pre-installed packages and built packages based on Spack recipes.
The following list shows the results of building/compiling packages for aarch64 according to the Spack recipes.
Note that the results in this list do not guarantee that each package will work properly.
On the other hand, Fujitsu will provide the following packages compiled with Fujitsu compiler on Fugaku as "external" packages, of which Spack can be aware.

py-uproot
ROOT I/O in pure Python and NumPy. Uproot is a reader and a writer of
the ROOT file format using only Python and Numpy. Unlike the standard
C++ ROOT implementation, Uproot is only an I/O library, primarily
intended to stream data into machine learning libraries in Python.
Unlike PyROOT and root_numpy, Uproot does not depend on C++ ROOT.
Instead, it uses Numpy to cast blocks of data from the ROOT file as
Numpy arrays.
