高通神经加工引擎(NPE)加载模型失败

Question

我遵循高通神经处理引擎教程以构建示例应用程序。

当应用程序加载模型发生错误时。错误消息以下

如何解决此问题？

Answer 1

求解的顺序如下：

1）如https://developer.qualcomm.com/software/snapdragon-neural-processing-engine-eengine-ai/getting-started of https://developer.qualcomm.com/software/snapdraware-compom

1）下载并打包Alexnet模型 具体，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）之后，您可能会遇到此问题：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.

要解决此问题，您可以在此处首先使用旁路（Android Studio"错误：在更新为3.0.0之后），因为这是AAPT2

的持续错误

3）如果仍未解决，请使用ADB Shell验证所有文件都在Android设备上：

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:
shell@msm8996:/storage/emulated/0/Android/data/com.qualcomm.qti.snpe.imageclassifiers/files $ 

我们在这里可以看到的是：问题是SNPE搜索不在正确位置的文件，因此您可以将目录移至正确的位置

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

b。目录是空的 - 因此您可以将预期数据推到正确的位置： 只需将其提取到某些目录，并从目录中提取：

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

它应该起作用。
