Running same code multiple times produces different outcomes, and adds weird priors to model. about elfi HOT 3 CLOSED

You are correct that rerunning code that builds the ELFI graph does not replace but appends new nodes. This behaviour is intended and allows flexibility, though it can cause confusion as well.

Add a call to elfi.new_model() in your script before building the graph.

That elfi.new_model() should definitely explained more clearly in documentation. I originally encountered this while defining both the simulator and the sampler in the same code shell and run it multiple times while writing the code. I think this is pretty common way to use elfi.

Yes, this can cause confusion, and I have added more explanation in the notebooks. It will take a while to have it updated in readthedocs.
