LIBSVM - A Library For Support Vector Machines
It looks like the old LibSVM library is still kicking around and being updated. Last release was a bug fix on July 2023.
Version 3.32 released on July 9, 2023. We fix some minor bugs.
Plus changes how to use in Python:
> pip install -U libsvm-official
The python directory is re-organized so
>>> from libsvm.svmutil import *
instead of
>>> from svmutil import *
