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.…

Thanks for the response.

Do you have an example of how I use dummy values here? I tried to read the other thread, but it was not obvious to me.
