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).

usually, you dont need to read the value of t, as DifferentialEquation is a theano Ops that would do that for you, are you getting some error if you remove .eval()?
