Dear maintainer(s) of octave-symbolic, here is a wild guess, inspired by a simple remark:
----------------8<------------------------------------ $ python3 -c "import six; print(six.integer_types)" (<class 'int'>,) $ python2 -c "import six; print(six.integer_types)" (<type 'int'>, <type 'long'>) ----------------8<------------------------------------ Would it be enough to patch octave-symbolic source, to replace 'sympy.core.compatibility.integer_types' by 'six.integer_types' ?
