Hi Juan, FYI - you forgot to reply to the mailing list in your previous email...
As for the problem, as Eric mentioned, it seems to be a problem with your plot_posterior_nodes function. That one is out of the matplotlib library, and I guess it belongs to the HDDM package. You might want to ask people in their mailing list for more help, Shawn On Wed, Jun 3, 2015 at 2:10 PM, Juan Wu <wujua...@gmail.com> wrote: > Shawn, > > Thanks so much for your prompt reply.
