Hi! I am trying to model a dataset where each object has a variable number of features. In particular, I am trying to build on a finite approximated beta process-bernoulli process type of model, where each object has a variable-length list of values drawn from a normal distribution, and where the …

If you update to the current master branch, it will give you a more informative error message showing you which RV is hitting the zero grad error. Looking at the code, it is likely that the RV errs is too little uncertainty - as @rlouf suggest, you can try setting it to a dummy variable: errs = np.…

As mentioned in a previous thread this may be due to an overflow somewhere. Try to go down the hierarchy with some dummy values to see the scale of the values of the variables as you go deeper.
