Qualcomm神经处理引擎（NPE）加载模型失败

我遵循Qualcomm Neural Processing Engine教程来构建示例应用程序。Qualcomm神经处理引擎（NPE）加载模型失败

当应用程序加载模型发生错误。以下

我怎样才能解决这个问题错误消息？

顺序来解决这个问题如下：

1）下载并打包alexnet模型作为https://developer.qualcomm.com/software/snapdragon-neural-processing-engine-ai/getting-started 具体的，您需要：

cd $SNPE_ROOT/examples/android/image-classifiers 
cp ../../../android/snpe-release.aar ./app/libs # copies the NPE runtime library 
bash ./setup_models.sh

2）后，你可能会面临这个问题： https://developer.qualcomm.com/forum/qdn-forums/software/snapdragon-neural-processing-engine-sdk/35375

/raw_alexnet.zip.flat: error: failed to read data meta data.

来解决这个问题，你可以在这里使用第一旁路（Android Studio "error: failed to read metadata" after update to 3.0.0），因为这是在aapt2正在进行错误

3）如果仍然没有解决，验证所有文件都在Android设备上使用亚行外壳：

adb shell 
sifiers/files $ ls -R /storage/emulated/0/Android/data/com.qualcomm.qti.snpe.i>ssifiers/files $ 

/storage/emulated/0/Android/data/com.qualcomm.qti.snpe.imageclassifiers/files/models/: 
alexnet 

/storage/emulated/0/Android/data/com.qualcomm.qti.snpe.imageclassifiers/files/models//alexnet: 
images 

/storage/emulated/0/Android/data/com.qualcomm.qti.snpe.imageclassifiers/files/models//alexnet/images: 
[email protected]:/storage/emulated/0/Android/data/com.qualcomm.qti.snpe.imageclassifiers/files $

我们可以在这里看到的是：一。问题是SNPE搜索文件不在正确的位置，因此您可以将目录移动到正确的位置

cd /storage/emulated/0/Android/data/ 
mv com.qualcomm.qti.snpe.imageclassifiers com.qualcomm.qti.snpe

b。该目录是空的 - 所以你可以预期的数据推到合适的位置：只是把它解压到某个目录，并从目录下执行：

adb push ./ /storage/emulated/0/Android/data/com.qualcomm.qti.snpe/files/models/alexnet/

，它应该工作。
