Graph addition of strings test failed

[ljulliar]

Hi, First of ll congratulations for the fantastic work you have done with this Ruby interface to TensorFlow. I just wanted to report I got today. A couple of days ago I went through the installation process step by step and it worked like a charm including the test suite at the end invoked through the "bundle exec rake test" command. Today I decided I had enough with those warnings from the TensorFlow library telling me that I wasn't using all the nice SIMD instruction set available on my CPU and I decided to recompile TF with the following options:

bazel build -c opt --copt=-mavx --copt=-mavx2 --copt=-mfma --copt=-mfpmath=both --copt=-msse4.1 --copt=-msse4.2 //tensorflow:libtensorflow.so

Everything went well except that after rebuilding the Ruvy extension all test passed successfully except this one below. Any idea why this is happening ?

Failures:

  1) Graph Addition of strings
     Failure/Error: expect(out_tensor[0]).to eq('TensorflowRuby')

       expected: "TensorflowRuby"
            got: "TensorflowRubylowRuby"

@ljulliar Thanks a lot for your query. Warnings are something that bothered me for some time but I ignored them because of this.
I am really sorry that I couldn't reply to you earlier, as I recently immigrated to Canada from India and it took me some time to get set up.
I have been looking at this and trying to replicate this.
I think this is most likely an internal issue and most likely I won't be able to resolve it myself, in which case I will talk to tensorflow team about it.
Aside from that I hope you have played with tensorflow.rb and I hope you have liked it, Feel free to tell me if you have any other queries.

Thanks
