Hi,
Based on the tutorial:
PyTorch Vulkan Backend User Workflow — PyTorch Tutorials 1.8.1+cu102 documentation 2
The operator _cat is supposed to be supported in the vulkan backend. Yet when I try run an exported model using it on android, I get the following error:
RuntimeError: Could not run 'aten::_cat' with arguments from the 'Vulkan' backend. This could be because the operator doesn't exist for this backend, or was omitted during the selective/custom build process (if using custom build). If you are a Facebook employee using PyTorch on mobile, please visit https://fburl.com/ptmfixes for possible resolutions. 'aten::_cat' is only available for these backends: [CPU, QuantizedCPU, BackendSelect, Named, AutogradOther, AutogradCPU, AutogradCUDA, AutogradXLA, Tracer, Autocast, Batched, VmapMode].
Is there any reason this is happening?
Thanks,
Julien
