Because Numpy was used for the final transpose for the logits output,
torch.onnx.export
would failIf this line at whisper/model.py:L192 is changed from
logits = (x @ self.token_embedding.weight.to(x.dtype).T).float()
to
logits = (x @ torch.transpose(self.token_embedding.weight.to(x.dtype), 0, 1)).float()
then the export succeeds!
