Pytorch FFT RuntimeError: FFT_INVALID_DESCRIPTOR

Hi all

I am working on a scientific solver based on pytorch. The software worked perfectly on Nvidia GPUs and Arm/x86 CPUs.

However, there was an error related to the FFT function when I ran it on an Intel GPU.

The error is down to the inverse real FFT call:

x = torch.rand(1000,1000,1,3).to(torch.device("xpu"))

torch.fft.irfftn(x)

which returns the error:

RuntimeError: FFT_INVALID_DESCRIPTOR

Hi,

Thank you for posting in Intel Communities.

Could you please share the below details:

1. OS and Hardware details

2. Torch and IPEX version

Thanks

Hi,

We have not heard back from you. Could you please give us an update?

Thanks

My apologies. I received the previous reply while having dinner and then completely forgot the issue.

I did open an issue on the intel GitHub repo.

I ran it on the jupyter dev cloud.

It seems that I can't simply post the log generated by the environment script on the forum directly (it was flagged as html)

Please refer to this reply

Hi,

Thank you for the response. We are checking on this internally.

Thanks

Hi Jed Cheng,

This issue is not reproducible on IPEX version 2.1. Please retry and let me know if the issue persists.
