@junpenglao I am able to run the example notebooks like Lotka-Voltrra as well some other simple examples ,as you told to wait for simulator to check in to PYMC3 ,I am free to contribute/help @agustinaarroyuelo and @aloctavodia to get it done asap so that we can work on some other features .
@agustinaarroyuelo and @aloctavodia , it would be great if you share some updates about your plans .
