SNPE no output

Hello,

I am trying to implement dlc model in an android app runing it on dsp.

However, when I set dsp as a runtime, the model does not return any output (while, it gives correct output on GPU and CPU runtime).

I have checked that the device has dsp module using snpe-platform-validator. Also, model runs perfectly fine when I tried snpe-net-run setting runtime as dsp.

Is there way to fix this problem?

 

Thank you

Hi,

Try specifying --use_dsp on your android target.

NOTE: The extra environment variable ADSP_LIBRARY_PATH must be set to use DSP.

Check the SNPE developer website for DSP RUNTIME ENVIRONMENT.

 

Thanks

Hello,

While testing snpe-net-run, I have read the DSP RUNTIME ENVIRONMENT page (Snapdragon Neural Processing Engine SDK: DSP Runtime Environment (qualcomm.com)) and I have set ADSP_LIBRARY_PATH.

The snpe-platform-validator gives "dsp device present" and it gives correct output on snpe-net-run.

While testing the dlc file on android project, I have checked that dsp is available using isRunTimeAvaliable and I have set ADSP_LIBRARY_PATH using code below.

bool SetAdspLibraryPath(std::string nativeLibPath) {

std::stringstream path;
path << nativeLibPath << ";/system/lib/rfsa/adsp;/system/vendor/lib/rfsa/adsp;/dsp";
 
return setenv("ADSP_LIBRARY_PATH", path.str().c_str(), 1 /*override*/) == 0;

}

However, the model gives empty output.

is it possible some model to work only on snpe-net-run but not on android project?

 

Thank you
