I got SNPE v1.40 and Snapdragon XR2 on Oculus Quest 2, and when I was testing TensorFlow Inception_v3 tutorial, the CPU run will pass, but GPU run always go into error

snpe-net-run --container inception_v3 --input_list target_raw_list.txt --gpu_mode=float16

The selected runtime is not available on this platform. Continue anyway to observe the failure at network creation time.
error_code=500; error_message=Target runtime is not available. error_code=500; error_message=Target runtime is not available. No viable runtimes available.; error_component=Host Runtime; line_no=328; thread_id=515297693008; error_component=Host Runtime; line_no=271; thread_id=515484020432

I followed some instructions to test if the snpe can identify the GPU, so I run

snpe-platform-validator --runtime all

and the result is

snpe-platform-validator --runtime all                                          <

I understand DSP maybe inaccisable by users since Quest2 uses the DSP to do real-time tracking computing, but as "Runtime GPU Prerequisites: Present.", I think the GPU is usable, so what caused the error shown in the beginning part?

 

Best,

Dear developer,

GPU backend only supported flloat dlc model and input data. You can try to convert model to dlc only rather than quantization progress.
