I have made a make shift install script in tools directory. You are free to use it, but it still needs some work and there is a chance that you might face some issues with it and if you do face some issues, you can use the instructions below. You are welcome to make improvements to the script.

It's easiest to get started using the prebuilt Docker container.

Launch:

docker run --rm -it nethsix/ruby-tensorflow-ubuntu:0.0.1 /bin/bash

Test:

cd /repos/tensorflow.rb/
bundle exec rspec

Image Classification Tutorial:

cd /repos/tensorflow.rb/image/
cat README

For more details about all the fun machine-learning stuff already pre-installed, see: https://hub.docker.com/r/nethsix/ruby-tensorflow-ubuntu/

Alternatively, you can install outside of a Docker container by following the following steps.

• Ruby >= 2.2.0
• Bazel
• TensorFlow
• Swig

• Google-Protoc gem ( for installation do gem install google-protoc --pre )
• Protobuf

All the dependencies mentioned above must be installed in your system before you proceed further.

This package depends on the TensorFlow shared libraries, in order to compile these libraries do the following:

git clone --recurse-submodules https://github.com/tensorflow/tensorflow
cd tensorflow
./configure

This command clones the repository and a few sub modules. After this you should do:

bazel build -c opt //tensorflow:libtensorflow.so

This command takes in the order of 10-15 minutes to run and creates a shared library. When finished, copy the newly generated libtensorflow.so shared library:

# Linux
sudo cp bazel-bin/tensorflow/libtensorflow.so /usr/lib/

# OSX
sudo cp bazel-bin/tensorflow/libtensorflow.so /usr/local/lib
export LIBRARY_PATH=$PATH:/usr/local/lib (may be required)

Clone and install this Ruby API:

git clone https://github.com/somaticio/tensorflow.rb.git
cd tensorflow.rb/ext/sciruby/tensorflow_c
ruby extconf.rb
make
make install # Creates ../lib/ruby/site_ruby/X.X.X/<arch>/sciruby/Tensorflow.{bundle, so}
cd ./../../..
bundle install
bundle exec rake install

The last command is for installing the gem.

bundle exec rake spec

This command is to run the tests.

You can run tensorboard on tensorflow.rb too. Just take a look at tensorboard.md file.
