Torch2.2 Error Variance about diffsinger HOT 5 CLOSED

Did you export your ONNX model with the right version of PyTorch (1.13)?

from diffsinger.

Yes, 1.13 can be converted correctly　The latest torch 2.2 is now mainstream, and the tool for creating training data some.sofa can only be used with pytorch 2.2.Since torch itself takes up a lot of space, installing multiple versions is also a hassle.

So you confirm your model is exported under PyTorch 1.13, and is used with the latest version of OpenUTAU? Please note that the ONNX exporter is only expected to work under PyTorch 1.13, and under other version it may break even if it seems to run successfully. Have you tried other projects? Does every project raise this error?

from diffsinger.

Yes, onnx exported with pytorch 1.13 can be used.pytorch2 cannot be reshaped and is exported, but cannot be used.

from diffsinger.

I can now confirm that you exported the model with PyTorch 2.2, because I tried PyTorch 2.2 and reproduced your error. This is due to a bug of PyTorch itself, and I will not fix it.

Anyway, I have told you that exporting the model sucessfully does not mean the model is correct, and PyTorch 1.13 is the only version that is tested and verified. Please install PyTorch 1.13 to export the model. Only the CPU-only version is enough so it will not take much space.
