I am trying to use TensorFlow Lite with GPU delegate on Android. I am using the lib version (.so files) built from sources from the master branch of the repo. The problem is: the ModifyGraphWithDelegate function always returns error. And there is the following error message in logs:
2019-04-22 15:21:16.212 688-688/com.my.app E/tflite: TfLiteGpuDelegate Prepare: Shader compilation failed: ERROR: 0:6: 'unknown' : not a legal layout qualifier id
ERROR: 0:6: 'unknown' : Syntax error: syntax error
INTERNAL ERROR: no main() function!
ERROR: 2 compilation errors. No code generated.
2019-04-22 15:21:16.212 688-688/com.my.app E/tflite: Node number 54 (TfLiteGpuDelegate) failed to prepare.
If I use JAVA/JNI prebuilt lib version ('org.tensorflow:tensorflow-lite:0.0.0-gpu-experimental') like in official example project - there are no such errors. But I really need to use C++ interface for my cross-platform code.
Any thoughts / suggestions appreciated.
If you're building native shared library then you might need to manually load the .so library.
See https://groups.google.com/a/tensorflow.org/forum/#!topic/tflite/5YhFsCFtKi4
I finally made it work. The internal reason of the error is still completely unknown for me but the point is:
The used (master branch) version of the TFLite GPU delegate for Android fails to properly prepare for running on GPU the standard (for regression task) output nodes combination = flatten + dense.
If replace it with reshape + convolution (pointwise) + squeeze, then it works fine.
I'm trying to debug native application in Eclipse. Unfortunately, when I run "Debug As-> Android Native Application" I see the following errors in the console:
[2014-09-10 21:03:48 - GenderDetector] Verify if the application was built with NDK_DEBUG=1
[2014-09-10 21:04:16 - GenderDetector] gdbserver output:
[2014-09-10 21:04:16 - GenderDetector] run-as: Package 'com.opencv.genderdetector' is unknown
If I try to add "NDK_DEBUT=1" to the ndk-build command I see the following errors:
[armeabi-v7a] Gdbserver : [arm-linux-androideabi-4.9] libs/armeabi-v7a/gdbserver
install: cannot stat ‘/home/yury/software/android-ndk/prebuilt/android-arm/gdbserver/gdbserver’: No such file or directory
make: *** [libs/armeabi-v7a/gdbserver] Error 1
Could someone please explain what I'm doing wrong?
Here is a steps that may help you :
Check if /home/yury/software/android-ndk/prebuilt/android-arm/gdbserver/gdbserver is exsits
Check if it has execution permission.
Add this path to your environment variables this maybe will help.
Make sure your android-ndk folder is complete as it comes from google when you download.
Regards.
Build your application like this : ndk-build NDK_DEBUG:=1 APP_OPTIM:=debug
This enables the debug flag and also creates symbol files used by the debugger. You will see 2 files gdbserver.so and gdb.setup created within jni/libs folder. After this is done, you are good to debug as native application.
I meet this error when I use android-ndk-r10. After I uses android-ndk-r10e, this error disappear.
I have an iOS Objective C code for iPhone that I am trying to convert into android using Apportable. The issue is that I am getting this error:
1 error generated.
scons: *** [Build/android-armeabi-debug/com.iapptechnologies.time/Users/Home/PhotoTastic/PhotoTastic/AppClasses/ViewController.m.o] Error 1

^
Any help would be much appreciated. Thanks!
It's strange that AssetsLibrary is not added automatically from parsing the xcode build.
A workaround is to add AssetsLibrary to the "deps" section of "add_params" in configuration.json
Note that AssetsLibrary is not available in the Starter version of the SDK. At least the Indie version is needed.
I think this will do,In xcode 5 it looks different but the path is the same
I use pugixml parse xml, it's work fine on ios. However, when I change to android, use './build_native.sh' (cocos2d-x for android) to build my project. There are some error:
pugi/pugixml.cpp: In member function 'void* pugi::impl::(anonymous namespace)::xpath_allocator::allocate(size_t)'
pugi/pugixml.cpp:5722:26: error: exception handling disabled, use -fexceptions to enable
someone can help me. thank you very much!
You have two options:
Enable exception handling using -fexceptions, if your platform supports it
Disable exception handling in pugixml by adding #define PUGIXML_NO_EXCEPTIONS to pugiconfig.hpp or to your build settings.
Need your guidance, I am writing one app in android with the help of native code which will communicate with CAN (Controller Area Network) port ; for that in my C code i used linux/can.h header file. and i am following "http://mobilepearls.com/labs/ndk-builder-in-eclipse/" this link to build my app. but one i set all thing i got bellow msg in eclipse console box
Compile thumb : can_port <= cansend.c
jni/cansend.c:14:23: fatal error: linux/can.h: No such file or directory
compilation terminated.
make: *** [obj/local/armeabi/objs/can_port/cansend.o] Error 1
One more thing, i am working on windows environment. But i don't think this may be cause.
It is correct that it is not a Windows/Linux problem. The simple problem is that compiler is unable to find the file can.h. Now, for your info, when the compiler starts compiling, it searches for its header files in the folder
C:\(path to NDK folder)\platforms\(android-version)\(arch)\usr\include\linux
Now, if there isn't a can.h there, the compiler will flag an error. So the best way is
Either copy can.h to the above path (not tested)
Modify your Makefile to path to the correct directory where this header file is kept
Hope this helps!
