recursiveCopy got nil in recursiveUtils.lua #386

Closed ghost closed 7 years ago

ghost commented 7 years ago

FastLSTM with MaskZero spit out nil error.

/root/torch/install/bin/luajit: /root/torch/install/share/lua/5.1/rnn/recursiveUtils.lua:44: expecting nested tensors or tables. Got nil and nil instead

@deepcoord how did you fix this?

@aep @ganeshjawahar Do your solve this question?
