Error when run with Brian2 simulator

[ferqui]

When I run examples with the brian2 simulator, I get the following error. Could you give me some suggestions? Thank you very much.

Hi,

Please try

self.eqs = 'v = 0 : 1'

It appears the zero has been dropped in a recent pull-request. I'll investigate.

@ferqui Please close if this pull-request fixed the issue.
