thank you for your reply!
I want to generate new vector ( size: 104,1) from an input vector (same input size) using the net. So I use a net with 2 layers. Each layer is made by a  1d CNN with ReLu activation function. The input/output are related through a linear function I didn’t post since is quite simple, but the problem seems to be inside the net… did I miss something in the code? It always runs but the output i get from the net is always equal to zero.
thank you!
