armnn: Errors when building Arm NN

Hi, @FrancisMurtagh-arm I am using the latest version of both TensorFlow (2.4.3) and armNN (21.08). I will try to use ARM NN 21.05 as @payaljindal suggest and see what I get. And the attachment is schema_generated.h file schema_generated.h.zip

Hi @HungYangChang, we support TensorFlow version 2.3.1, as mentioned in our release notes, could you try with ArmNN 21.08 and Tensorflow 2.3.1?

@payaljindal Thanks for the nice explaining. Also, I think shape_signature in tflite parser is somehow missing or not working correctly. Could @FrancisMurtagh-arm check that?

Thanks for your help in advance 😃

Hi @FrancisMurtagh-arm, I used a different version of Arm NN(21.05). Now, I am able to build successfully.

Thanks, Payal

@payaljindal May I ask which version of ARM compute library are you using? Is it 21.08 or 21.05?

Hi @FrancisMurtagh-arm, I used a different version of Arm NN(21.05). Now, I am able to build successfully.

Thanks, Payal

Hi @HungYangChang & @payaljindal,

Could you post your schema_generated.h and confirm your Tensorflow version?

Thanks, Francis.

@payaljindal I still cannot figure that out. But I will update here if I get any progress. I think ARM developers might reply on Tuesday since Monday is Labor day.

I am also facing the same error. @HungYangChang if you found any solution, please put it here as well. Thanks in advance.

Hello @FrancisMurtagh-arm

I tried to follow your sugeestion

$ mkdir tflite
$ cd tflite
$ cp $BASEDIR/tensorflow/tensorflow/lite/schema/schema.fbs .
$ $BASEDIR/flatbuffers-1.12.0/build/flatc -c --gen-object-api --reflect-types --reflect-names schema.fbs

And here is the tflite path:

shunya@hikey970:~/hungyang/armnn-dist/tflite$ ls
schema.fbs  schema_generated.h

And then I use the following command

cmake .. -DARMCOMPUTE_ROOT=$BASEDIR/ComputeLibrary 
-DARMCOMPUTE_BUILD_DIR=$BASEDIR/ComputeLibrary/build 
-DSHARED_BOOT=ON 
-DBOOST_ROOT=$BASEDIR/boost

-DTF_LITE_GENERATED_PATH=/home/shunya/hungyang/armnn-dist/tflite 
-DFLATBUFFERS_ROOT=$BASEDIR/flatbuffers-1.12.0 
-DFLATBUFFERS_LIBRARY=$BASEDIR/flatbuffers-1.12.0/libflatbuffers.a
-DFLATC_DIR=$BASEDIR/flatbuffers-1.12.0/build 
-DARMCOMPUTENEON=1 
-DARMNNREF=1

I also find out link (in Mandarin) have a similar issue. Thanks for the help in advacne.

Hi @HungYangChang,

You appear to be using the incorrect DTF_LITE_GENERATED_PATH, it should be pointing to a file called schema_generated.h not what you have /home/shunya/hungyang/armnn-dist/flatbuffers-1.12.0/build/tflite

This is generated using:

/usr/bin/flatc -c --gen-object-api --reflect-types --reflect-names -o path/we/output/to path/to/tensorflow/schema.fbs

In the link you provided there seems to be a typo in schema.fbs:

$ mkdir tflite
$ cd tflite
$ cp $BASEDIR/tensorflow/tensorflow/lite/schema/schema.fbs .
$ $BASEDIR/flatbuffers-1.12.0/build/flatc -c --gen-object-api --reflect-types --reflect-names schema.fbsS   # note extra S

I’ll put a request in for the document to be updated for the typo

Thanks, Francis.
