Python3 support for opencog/atomspace

[Eyob]

So we have an intern at icog labs who is interested in making python3 bindings for opencog/atomspace.

If anybody wants to give him guidance on how to go about it, please write him here or here https://github.com/opencog/atomspace/issues/501

His github username/profile  is   https://github.com/Yididya/

Hope he would be asking for pull requests soon :D

I was wondering does every part of opencog/atomspace need to be built using python3 or we can proceed part by part. E.g.

It seems i really like this import statement to work right now

from opencog.scheme_wrapper import scheme_eval

in python3 but the error reads " ImportError: No module named 'opencog' " when executed.

Its like at the moment we need python3 bindings only for a small number of import statements, for a project we are doing now currently.

Thanks!

This sounds great! We just needed python3 binding for OpenCog to send an output of a DNN to PLN in one script without additional wrappers.

There's really only one part: the C code that interacts with cython. its call in cython/PythonEval.cc  I'll bet that if you can get that to work, everything else will work without any porting. That's my guess.

There already exists a python3 branch in the atomspace repo unfortunately I never got it to work. This also contains a lot of changes I did trying to get it to work but didn't help that might have to be reversed. And the branch is over 2 years old not sure how much the python interface has changed since then but might still be worth looking at it.

HI Roman, could you repost this directly on
https://github.com/opencog/atomspace/issues/501 where it won't get
lost? --linas

So it seems opencog/atomspace has finally been ported to python3. Thanks Linas for doing the work :D
