Support for Radeon GPUs?

[viggy96]

Description

Support Radeon GPUs to be used for accelerating inferencing and training

Will this change the current api? How?
No

Who will benefit from this enhancement?
All users of Radeon GPUs

I've tried using the PyTorch ROCm version from here
https://repo.radeon.com/rocm/manylinux/rocm-rel-6.0/README.html
And it does work according to these validation instructions:
https://rocm.docs.amd.com/projects/radeon/en/latest/docs/install/install-pytorch.html#verify-pytorch-installation

However I get the following error when running my project:

Has DJL ever used Radeon GPUs?

@viggy96

We don't support ROCm, you can try to build PyTorch JNI for ROCm by yourself. See: https://github.com/deepjavalibrary/djl/blob/master/engines/pytorch/pytorch-native/build.sh#L26

@viggy96

You actually can use DJL with ROCm using OnnxRuntime engine, see: https://github.com/deepjavalibrary/djl/blob/master/engines/onnxruntime/onnxruntime-engine/src/main/java/ai/djl/onnxruntime/engine/OrtModel.java#L212-L213

[viggy96]

That sounds great, do you have any object detection inference examples using OnnxRuntime?
