we use pytorch version of 1.7.0+cu101 to turn torchscript，and I successfully loaded the torchscript model in torch version of 1.7.0+cu101 to inference, but when I use pytorch version of 1.8.1+cu101 to inference, there are some error

we use torchaudio to change audio speed,volume and so on, please help me
when we create torchscript the pytorch version is 1.7.0+cu101 , the torchaudio version is 0.7.0
