this project is amazing! i change the SelectiveScanOflex to SelectiveScanEasy for cpu inference, but the result have Nan, i found it cause by tmp_dtBus_div_rAts = (dtBus / rAts), the rAts have zero value, how to fix this?

It is only a toy version of code. For code that is appliable in practise, use mamba-2 instead.
