Forums - failed to run Inception_v3 tutorial on DSP

Dear customer,

Related SNPE skel libs will port into /vendor/lib/rfsa/adsp on target. Also, DSP only supported fixed point tensor of model to execute. You need to quantize the model with command of snpe-dlc-quantize.

Hi,

Can you provide the commands or links which you are following. It will be helpful to reslove errors 

I have quantizee the model with command of snpe-dlc-quantize, and run snpe-net-run --container inception_v3_quantized.dlc --input_list target_raw_list.txt on OnePlus 8T,But it also failed to run in the mode --use_dsp. It shows "Aborted". because "/system/lib/rfsa/adsp" and "/dsp" cannot be found on this system??? and how can I solve this problem???

Hi 493744520,

If you are trying to build the android app for inferencing, Please make sure that you have followed the guide given on this page.

Snapdragon Neural Processing Engine SDK: DSP Runtime Environment (qualcomm.com)
 

For Android APKs

ADSP_LIBRARY_PATH must be set for Android APKs as well, and it cannot be done using an "export" command. It must be done within code running in the APK.

The SNPE Android Java APIs automatically sets the ADSP_LIBRARY_PATH. The supplied SNPE Java AAR library automatically sets up the DSP environment for your Android application.

Android applications that do not use the SNPE Java AAR must set the ADSP_LIBRARY_PATH explicitly in native code. An example is provided 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;

}
