pytorch轉onnx模型多輸入問題（如：Bert）

舉個例子：
Bert模型有三個輸入，因此就要創建三個dummy_input，然後利用一個tuple，傳入函數中。

dummy_input0 = torch.LongTensor(Batch_size, seg_length).to(torch.device("cuda"))
dummy_input1 = torch.LongTensor(Batch_size, seg_length).to(torch.device("cuda"))
dummy_input2 = torch.LongTensor(Batch_size, seg_length).to(torch.device("cuda"))
torch.onnx.export(model. (dummy_input0, dummy_input1, dummy_input2), filepath)
