IndexError: index 1 is out of bounds for axis 0 with size 1

Hello I'm running the Demo for 100 cells with time and its working for ODE part and I could get the plots however for SDE part I got this error Model being initialized...

IndexError Traceback (most recent call last)

Thank you

Hi, could your x0 be a 1D tensor? It should be of shape [N,n] where N is the number of initial values and n is the state dimensionality.
