Error on building for expert.py

[huythach]

I succeeded on building beginner.py and expert.py to beginner-graph.pb and expert-graph.pb files to be used in the Android project. But when I replaced these files in the app/src/main/assets/ only beginner-graph.pb works, expert-graph.pb does not work.
Do you have any idea?
(I have modified file DigitDetector.java in lines 43 and 46 to use beginner-graph.pb and expert-graph.pb, respectively).

I copy the error log as follows:

Did you manage to figure out how to fix Could not create Tensorflow Graph: Invalid argument: NodeDef mentions attr 'Tshape' not in Op<name=Reshape; signature=tensor:T, shape:int32 -> output:T; attr=T:type>; NodeDef: Reshape = Reshape[T=DT_FLOAT, Tshape=DT_INT32](input, Reshape/shape) by any chance?

I tried copy and pasting the the tensorflow/tensorflow folder in the include/tensorflow folder and regenerated the .so file but I still get the same error. I also tried manually editing array_ops.cc with the "Reshape" op from Tensorflow 0.11.0 but I still get the same error.

I didn’t manage that problem. But it seems that we need to use freeze_graph.py from Tensorflow tools to create graph.pb file.
I am trying to do in that way, if I succeed, I will feedback you.

From the the replies from my issue at tensorflow/tensorflow#5585 at the Tensorflow GitHub, it seems like that the problem comes up because the Tensorflow used to generate the .PB-file is 0.11.0 whereas the Tensorflow version on Android is at 0.10.0.

EDIT: I managed to fix the error. How I did it can be found at tensorflow/tensorflow#5585.

[huythach]

if possible, could you send me a sample of your project?
I am still working on TensorflowAndroidMNIST but it does not work.

[leslietso]

My internet is very slow (16kb/s upload) but I will upload my jni-build folder to Google Drive sometime next week.

[leslietso]

Here you can find my jni-build file. It is quite large (800MB+) because I was not sure what I could delete.

[huythach]

Thank you very much,
I will try it.

@leslietso May I ask you for a quick review on the steps you've performed to get the app built? I would also like to integrate a newer version of Tensorflow into my Android-Studio system. But I have absolutely no clue how I should proceed with building the new binaries and include directories..

Building the Demo-App and copying the .lo .o files is ok, but the files in the /include folder are still the old ones, right? Where can I find the new ones? Thanks :)

[leslietso]

Sorry for the late reply. I simply downloaded the newest repo from Tensorflow, built it, then copied the contents of "tensorflow/tensorflow" folder to the "jni/include/tensorflow" folder and the contents of "tensorflow/third_party" to "jni/include/tensorflow". I have little experience with Tensorflow and am in no way an expert so the "jni_build" file does end up very big (over 800MB) as it is not optimized and includes all files whether I need it or not.

[beniroquai]

Ah. Great. Thanks! You built it using bazel, right? Because there is also a CMAKE version nowadays.
So, in case I get any errors which says something like function not implemented or so, I "just" edit the bazel build file and include the headers in the new build? Do I also need new jni-header-files then?
I think in one of my experiments the dropout was not implemented..maybe in 0.12 it changed already..

@leslietso @huythach Hi all,I also have this issues--" Could not create Tensorflow Graph: Invalid argument: NodeDef mentions attr 'Tshape' not in Op<name=Reshape; signature=tensor:T, shape:int32 -> output:T; attr=T:type>; "

Now tensorflow update to r1.0.I don't know how to build it to fit this issues.Can you help me?

[JcmeLs]

@leslietso Thanks for your share "jni-build".My app can run now.But I want to know that how to fix it.How to build tensorflow can get genfiles's file?

[datomnurdin]

Any solution so far?
