> In SINGA_HOME/src/work.cc, in “int Worker::CollectAll(int step, NeuralNet* net){}”
function, the layers which are unrolled (except for the first one) should not collect parameters,
due to parameter sharing.
> Previous:
> if (layer->partition_id() == id_)
> Possible changes:
> if (layer->partition_id() == id_ && layer->unroll_index() == 0)
