I also tried the way it was discussed here:Saving ADVI results and reloading . But when i try to use the saved paramters in approx and apply it back to get inference it takes a lot of time (I had to stop the process because my computer was stuck) because of large dataset size.
In the discussion you have mentioned that the model needs to be same, but when I try to use the same model and then run it, it just cant handle it. Then how can i possibly use that approx object to get inferences on my local.
