I'm having some problems trying to use a program called Brian Simulator (www.briansimulator.org) through Sage. This program is written in Python an can be used as a python package (I've tried it and I had no problem). However, when I try to use it in Sage I get some problems involving units, which are defined inside Brian. For example, if I write:
sage: from brian import * sage: 1*mV I get the following error: AttributeError Traceback (most recent call last) /home/uri/<ipython console> in <module>() /home/uri/sage-4.3.1/local/lib/python2.6/site-packages/sage/structure/ element.so in sage.structure.element.RingElement.__mul__ (sage/ structure/element.c:10382)() /home/uri/sage-4.3.1/local/lib/python2.6/site-packages/sage/structure/ coerce.so in sage.structure.coerce.CoercionModel_cache_maps.bin_op (sage/structure/coerce.c:6145)() /home/uri/sage-4.3.1/local/lib/python2.6/site-packages/brian/units.pyc in __mul__(self, other) 1063 if isinstance(other,Unit): 1064 u = Unit(float(self)*float(other)) -> 1065 u.name = self.name + other.name 1066 u.dispname = self.dispname + ' ' + other.dispname 1067 u.dim = self.dim * other.dim AttributeError: name Does somebody know why it happens and how to avoid this error? What I don't understand is that if I just write: sage: mV there's no problem at all. Thank you in advance!!
