Hi,
I’m trying to run the spaun model available on github (GitHub - xchoo/spaun2.0: Spaun (nengo 2.0 version)). I already ran into some errors that I was able to fix thanks to an earlier post (Spaun 2.0 fails with "ModuleNotFoundError: No module named 'nengo.utils.compat'").
So after using nengo<3.0.0, python3.7, and numpy<=1.16.2, I ran into this error:
ImportError: /home/akl-ma/Downloads/spaun2.0-master/_spaun/arms/three_link/py3LinkArm.so: undefined symbol: _Py_ZeroStruct
During handling of the above exception, another exception occurred:

I tried recompiling based on the insructions in the readme but then I ran into this error:

Any help is appreciated, thanks!
