Forums - Does SNPE 1.13 support DSP?

Yes, I've foillow the user's guide again:

1st, push the libraries like this:

export SNPE_TARGET_ARCH=arm-android-gcc4.9
export SNPE_TARGET_STL=libgnustl_shared.so

adb shell "mkdir -p /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/bin"
adb shell "mkdir -p /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib"

adb shell "mkdir -p /data/local/tmp/snpeexample/dsp/lib"
adb push $SNPE_ROOT/lib/$SNPE_TARGET_ARCH/$SNPE_TARGET_STL \
          /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib
adb push $SNPE_ROOT/lib/$SNPE_TARGET_ARCH/libsymphony-cpu.so \
          /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib
adb push $SNPE_ROOT/lib/$SNPE_TARGET_ARCH/libsymphonypower.so \
          /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib
adb push $SNPE_ROOT/lib/dsp/libsnpe_dsp_skel.so \
          /data/local/tmp/snpeexample/dsp/lib
adb push $SNPE_ROOT/lib/dsp/libsnpe_dsp_v65_skel.so \
          /data/local/tmp/snpeexample/dsp/lib
adb push $SNPE_ROOT/lib/$SNPE_TARGET_ARCH/libsnpe_adsp.so \
          /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib
adb push $SNPE_ROOT/lib/$SNPE_TARGET_ARCH/libsnpe_cdsp.so \
          /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib
adb push $SNPE_ROOT/lib/$SNPE_TARGET_ARCH/libsnpe_cdsp_v65.so \
          /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib
adb push $SNPE_ROOT/lib/$SNPE_TARGET_ARCH/libSNPE.so \
          /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib
adb push $SNPE_ROOT/bin/$SNPE_TARGET_ARCH/snpe-net-run \
          /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/bin

2nd, push pictures and dlc file like this

cd $SNPE_ROOT/models/inception_v3
mkdir data/rawfiles && cp data/cropped/*.raw data/rawfiles/
adb shell "mkdir -p /data/local/tmp/inception_v3"
adb push data/rawfiles /data/local/tmp/inception_v3/cropped
adb push data/target_raw_list.txt /data/local/tmp/inception_v3
adb push dlc/inception_v3_quantized.dlc /data/local/tmp/inception_v3
rm -rf data/rawfiles
 

Then we get this result :
snpe-net-run --container inception_v3_quantized.dlc --input_list target_raw_list.txt --use_dsp          <
The selected runtime is not available on this platform. Continue anyway to observe the failure at network creation time.
error_code=101; error_message=Invalid parameter in user config. Attempted to set a neural network configuration option DSP that is not supported on this platform.; error_component=System Configuration; line_no=107; thread_id=-354147160

Then I do it by my example like this :
1st, compile the native cpp file

cd ~/snpe-sdk/examples/NativeCpp/SampleCode

$ ndk-build NDK_TOOLCHAIN_VERSION=4.9 APP_STL=gnustl_shared
jni/Android.mk:8: "the value of LOCAL_PATH is jni TARGET_ARCH_ABI is armeabi-v7a"
jni/Android.mk:9: /home/yuepx1027/snpe-sdk
jni/Android.mk:8: "the value of LOCAL_PATH is jni TARGET_ARCH_ABI is arm64-v8a"
jni/Android.mk:9: /home/yuepx1027/snpe-sdk
[armeabi-v7a] Prebuilt       : libSNPE.so <= /home/yuepx1027/snpe-sdk/lib/arm-android-gcc4.9/
.........//here we compiled normally.
[arm64-v8a] Executable     : snpe-sample
[arm64-v8a] Install        : snpe-sample => libs/arm64-v8a/snpe-sample
[arm64-v8a] Install        : libgnustl_shared.so => libs/arm64-v8a/libgnustl_shared.so

2nd, I push the libraries and snpe-example to device:

export SNPE_TARGET_ARCH=arm-android-gcc4.9
export SNPE_TARGET_ARCH_OBJ_DIR=armeabi-v7a
adb shell "mkdir -p /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/bin"
adb shell "mkdir -p /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib"
adb shell "mkdir -p /data/local/tmp/snpeexample/dsp/lib"
adb push $SNPE_ROOT/lib/$SNPE_TARGET_ARCH/ /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib
adb push $SNPE_ROOT/lib/dsp/ /data/local/tmp/snpeexample/dsp/lib
adb push $SNPE_ROOT/examples/NativeCpp/SampleCode/obj/local/$SNPE_TARGET_ARCH_OBJ_DIR/snpe-sample /data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/bin

3rd, execute the naitve example like this:

adb shell
export SNPE_TARGET_ARCH=arm-android-gcc4.9
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/lib
export PATH=$PATH:/data/local/tmp/snpeexample/$SNPE_TARGET_ARCH/bin
cd /data/local/tmp/alexnet
snpe-sample -b ITENSOR -d bvlc_alexnet.dlc -i target_raw_list.txt -o output_sample
exit

Then I'll get the logs below:

SNPE Version: 1.13.0.0
Runtime is GPU ...1.13.0.0
Force Runtime to DSP ...1.13.0.0
Segmentation fault

Here is my modifications:

 }
 

What's my mistaked?

Waiting for your kind reply.

Thanks
