Mps does not work with projects using Torchtext

Hi Pytorch,

Great work everybody to bring Pytorch to Mac M1s! I am working on a text classification problem.
I installed a nightly version of Pytorch to use mps backend. However, I can only install the version 0.12.0 of torchtext and which throws the error of

ImportError: Symbol not found

I believe it is because of the version mismatch. I noticed there are wheels available for torchtext version 0.13.0 but sadly not for M1 (arm chip).
Should I wait for the next version of torchtext ?
Or is it another problem?

Thanks in advance.

Hi,

Thanks for the report!
This is indeed “expected” today: domain libraries do not provided nightly builds for arm. So you are getting the latest released version which is not binary compatible with a nightly version of torch.

As of right now, you can build torchtext from source to solve this.
We are also working on making these builds available (you can track Add TorchVision wheel build for M1 by malfet · Pull Request #5948 · pytorch/vision · GitHub for torchvision and we’re working on similar PRs for text and audio).

Hope this helps!
