Hi, are you interested in ahead-of-time compilation (called creating a “bundle” in Glow terminology), or in JIT compilation? You can use image-classifier for both purposes, or model-compiler for ahead of time.
There are some examples for AOT here 30 and JIT here 21.
For GPUs, the best we have right now is our OpenCL backend. Otherwise there’s not much open source GPU support currently, as we have focused Glow more on supporting specialized accelerator HW for inference such as Intel’s NNPI, Habana’s Goya, etc.
