Question about the feature of diverse sampling

[itsnickchiu]

Thanks for your great work, really appreciate it!

From the code implementation, what I understand is that users can simply turn on the --sample flag, and the system leverages the capability of dropout to make the system generate diverse outputs given the same input pair. However, it seems that the outputs typically are the same even if I turn on the flag.

I wonder where should I modify or is there any detail I do not notice to make the system only generate the deterministic outputs.

Best,
Nick
