Follow-up Comment #2, bug #45478 (project octave):

I don't even get past your first line:


octave:11> E1 = sym('E1')
pydebug: error exporting variable:
pydebug: x: <function E1 at 0x7ffba2572140>
pydebug: type: <type 'function'>
E1 = python does not know how to export type <type 'function'>


"E1" is apparently assigned the function expint().

1.  But you don't get that error, which is strange!  Can you try just the "E1
= sym('E1')" line as above and let me know?

2.  It is supposed to be possible (in SymPy) to override these sorts of
default symbols, so I'm surprised by this error.  I will investigate.
