the main issue, is you’d need to move from python2.7 to python3, and given the code base this is non-trivial
I documented the last attempt I had at it - you’ll also find a python3 branch in GitHub (untested and incomplete !!!)
https://community.polyexpression.com/t/eigend-upgrade-to-python-3
also its not just python code that needs to be updated/modified…
EigenD integrates python and c++, in a multithreaded environment, which has important issues/limitations for python.
before the python 2 eol, I tried to upgrade to the latest version of python 2, and found that this introduced (new) thread blocking issues due to this, and I would expect the same is true of python3.
so its non trivial,
you’ll need experience of C++ / Python with multi-threading experience to get anywhere. also there is a lot of pretty complex code, it also has a pretty archaic build system (scons) - but feel free to have a look / go.
btw: due to its complexity, I wont accept any automated converted / ai generated code into the repo - theres just too many ‘gotchas’ that would cause bugs, that’ll be nigh impossible to track down.
ofc, in your own fork you can do what you like 
as Ive mentioned elsewhere, I keep going around in circles on this one.
on one hand, EigenD is pretty good, and is ‘feature rich’, so Id love to get the code base built on moderns tools etc. so… Ive tried this a few times.
on the other, the code base is very difficult to work with, and I often think its easier to build what I need from scratch using EigenLite.
so, this has led me to create various projects based off this approach.
personally, at the moment, Im leaning more to the latter.
I think having applications with fewer dependancies, and a more focused code base is a better / more supportable solution.
anyways, as I said, Ive made plenty of posts on my thoughts, and also the current situation/issues with the code base - so Id advise checking those out before diving in… as it’d easy to spend a week messing with code, only to find out complications Ive already posted about
