Show FusionGroup for JIT script

In Torchscript sample RNN there was FusionGroup shown when printing graph for LSTMCell, but when i’m try to run torchscript LSTMCell from site and print graph, it’s not show a FusionGroup. Is that normal or there something missing for show FusionGroup like torch._C._jit_set_profiling_executor(False)?

It is TensorExprGroup with the new executor, and these should appear after second invocation (for cuda, cpu fusion is off by default).

torch._C._jit_set_profiling_executor(False) may also be a good idea with varying shapes.
