I am using DifferentialEquation and have defined function SIR which is form f(y,t,p) where t is a TensorVariable. I try to read its values (it should hold an integer) but I cannot do that. t.eval() creates an error “MissingInputError: Undeclared input”. Any ideas how I could read tensor t and this …

[image] Andrew_Davids: I would like to read an element of array arr using correct corresponding time index, meaning arr[t]. Also, if t is int type, arr[t] would work if arr is a theano tensor (if not you can do theano.shared(arr) to convert it).

I think I got it right now!

t_int = t.astype('int32') was required at the beginning of my SIR-function. Thanks!
