RuntimeError: Trying to create tensor with negative dimension -6: [-6, 256]

Hello @rishikksh20 , thanks for your sharing. I have some issues in training model.

    hs = self.length_regulator(hs, ds, ilens)  # (B, Lmax, adim)
  File "/data/tuong/Yen/AdaSpeech/env/lib/python3.7/site-packages/torch/nn/modules/module.py", line 1051, in _call_impl
    return forward_call(*input, **kwargs)
  File "/data/tuong/Yen/AdaSpeech/core/duration_modeling/length_regulator.py", line 63, in forward
    xs = [self._repeat_one_sequence(x, d) for x, d in zip(xs, ds)]
  File "/data/tuong/Yen/AdaSpeech/core/duration_modeling/length_regulator.py", line 63, in <listcomp>
    xs = [self._repeat_one_sequence(x, d) for x, d in zip(xs, ds)]
  File "/data/tuong/Yen/AdaSpeech/core/duration_modeling/length_regulator.py", line 93, in _repeat_one_sequence
    out.append(x_.repeat(int(d_), 1))
RuntimeError: Trying to create tensor with negative dimension -6: [-6, 256]

and gradient is not updated WARNING - grad norm is nan. Do not update model. Can you help me solve this issue? Thanks you.
