Hi,

I am currently working on a project in which I use a neural network with 3 feature inputs. The first one (localPosScore) is a 1x9 vectors and the others (msgX) are 1x7 vectors :

I create an arrayDatastore from a cell array with my training datas and the read function gives me this result :

However when I use the trainNetwork function the command answers me this error

Error using trainNetwork (line 184)

Input datastore returned more than one observation per row for network input 1.

I don't where I miss something because when I read the trainNetwork's help page I have a cell array of {numInputs+1} elements with a categorical label.

May you help me to solve this probem ?

Thanks in advance

Mathieu
