'//tensorflow:workspace.bzl': file doesn't exist or isn't a file.

[Alexander Sommer]

Hi, 

 

I tried to install tensorflow with android, according to the official install manual, but i am coping with an error that bazel cannot find the workspace.bzl file

alex@alex-VirtualBox:~/tensorflow$ bazel build //tensorflow/examples/android:tensorflow_demo --verbose_failures

ERROR: com.google.devtools.build.lib.packages.BuildFileContainsErrorsException: error loading package '': Extension file not found. Unable to load file '//tensorflow:workspace.bzl': file doesn't exist or isn't a file.

I would be very thankful for any hint.. 

thx

Did you ran ./configure beforehand?

No, you don't run like this. It is not a command of Bazel tool, like build, run or test.

'configure' is a shell script you run alone (it is part of autotools). 

So instead of 'bazel ./configure' you run it in your command line shell like this:

$ ./configure

Are you trying to build tensorflow from source following the instructions from https://github.com/tensorflow/tensorflow/blob/master/tensorflow/g3doc/get_started/os_setup.md?

Hi, 

I just re-checked out tensorflow, now the workspace.bzl file is here, but i am struggling with another error message:

no, i am a huge step further now, i can bazel start to run, but the process stops with:

Do you have build tools version 23.0.1 installed in your android sdk?

You can check with

$ ls <android-sdk>/build-tools

and seeing what versions are available there.

You can install / update new sdk build tools by running the sdk manager with <android-sdk>/tools/android

then update the build_tools_version attribute of the android_sdk_repository rule in your WORKSPACE file

[Alexander Sommer]

i just looked in my folder, and yes, i have 23.0.1

[Alex Humesky]

As a sanity check, can you check that aapt is in the 23.0.1 directory?

can you try without the sandbox? --spawn_strategy=standalone

finally, the magic was this: 

sudo apt-get install libc6:i386

sudo apt-get install zlib1g-dev:i386

aha, right, that's a very misleading message when a binary can't find its libraries.

hi, 

here is the full doc (at least, what we did to run it)

1- Install oracle-java according to the answer provided in this link:

- http://askubuntu.com/questions/430434/replace-openjdk-with-oracle-jdk-on-ubuntu

2- Open a terminal and enter this line (it will install pip3 for python3):

$ sudo apt-get install python3-pip

3- For the CPU only version of tensorflow, enter these lines in the terminal:

$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.10.0-cp35-cp35m-linux_x86_64.whl

$ sudo pip3 install --upgrade $TF_BINARY_URL

4- Test so if the tensorflow is installed, enter these lines in a terminal:

$ python3

>>> import tensorflow as tf

If you see no error, you are good to go. Open a new terminal or type exit() and hit enter.

5- Install bazel ( if it asks for [y,n], choose y and hit enter):

$ sudo apt-get install software-properties-common

$ $ echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list

$ curl https://storage.googleapis.com/bazel-apt/doc/apt-key.pub.gpg | sudo apt-key add -

$ sudo apt-get update && sudo apt-get install bazel

$ sudo apt-get upgrade bazel

6 - Download android studio, and then extract it to Downloads folder (You can extract it anywhere you like, but remember the path).

8 - Enter these two lines in a terminal:

$ sudo apt-get install libc6:i386

$ sudo apt-get install zlib1g-dev:i386

9 - Open android studio:

- cd to the folder android-studio/bin and then type ./studio.sh in the terminal and hit enter.

10 - Download ndk version r11c with this link and extract it into Downloads folder (You can extract it anywhere you like, but remember the path):

- https://dl.google.com/android/repository/android-ndk-r11c-linux-x86_64.zip

11 - Install git, so you could clone tensorflow git repository:

$ sudo apt install git

13 - Clone the git repository of tensorflow with this line in the terminal:

$ git clone https://github.com/tensorflow/tensorflow

14 - cd into tensorflow folder, Open a terminal and type:

$ cd tensorflow

And enter these lines in the same terminal where you are in the tensorflow directory (so you will add the assets directory to android example):

$ curl -L https://storage.googleapis.com/download.tensorflow.org/models/inception5h.zip -o /tmp/inception5h.zip

$ unzip /tmp/inception5h.zip -d tensorflow/examples/android/assets/

15 - Open the WORKSPACE file in the tensorflow root folder.

- Change and uncomment the lines for the path of NDK and SDK.

- Mine was like this:

android_ndk_repository(

        name="androidndk",

        path="/home/shahryar/Downloads/android-ndk-r11c",

        api_level=21)

android_sdk_repository(

        name = "androidsdk",

        api_level = 24,

        build_tools_version = "24.0.3",

        # Replace with path to Android SDK on your system

        path = "/home/shahryar/Android/Sdk",

        )

16 - Now in the same terminal (where you have cd to tensorflow), type this in the terminal:

$ ./configure

and then type the default path for python3 like this:

$ /usr/bin/python3

and choose N (NO) ([y/N]) whenever it asks for it (maybe 2 times).

17 - Now cd to Workspace root folder and enter this in terminal:

$ bazel build //tensorflow/examples/android:tensorflow_demo

18 - And you can find the .apk files in the tensorflow/bazel-bin/tensorflow/examples/android
