traced_model

[HongyanJiao]

when I ran: traced_model = torch.jit.trace(model, (input_ids,))
I got:
/home/jhy/py3.6/lib/python3.6/site-packages/torch/tensor.py:389: RuntimeWarning: Iterating over a tensor might cause the trace to be incorrect. Passing a tensor of different shape won't change the number of iterations executed (and might lead to errors or silently give incorrect results).

Hi! Could you show the inputs you use to trace your model?
