example.rb giving undefined method `length' error

[obromios]

I have asked the following question on stackoverflow but have had no answer:

I have installed tensorflow.rb using docker, as described. When I run bundle exec rspec spec, all examples pass.

I have created a file example.rb as instructed. When I run the file using ruby example.rb, I get the following error

/usr/local/rvm/gems/ruby-2.2.4@ruby-tensorflow/gems/tensorflow-0.0.1/lib/tensorflow/session.rb:168:in `graph_def_to_c_array': undefined method `length' for nil:NilClass (NoMethodError)
    from /usr/local/rvm/gems/ruby-2.2.4@ruby-tensorflow/gems/tensorflow-0.0.1/lib/tensorflow/session.rb:51:in `extend_graph'
    from example.rb:9:in `<main>'

When I run each line of example.rb in an irb session, the error occurs at the command:

session.extend_graph(graph)

How do I fix this?

I've followed up with a question over there.

I have replied to your query on stack overflow.

@nethsix Do you know why the docker image is not pulling in the latest commit? http://stackoverflow.com/questions/39995058/ruby-gem-tensorflow-rb-example-not-working?noredirect=1#comment67337965_39995058

I think the issue here is that docker is not really using the latest repository. The current repository has around 80+ tests whereas the docker version would have around(40-50 tests I am not sure of the exact number). (@nethsix might know why this is happening ) @obromios Would it be possible for you to make use of the long install instructions given in the Wiki (They are most likely going to work fine for you)? We will try to fix this issue as soon as possible or I will upload a new docker image.

Hi

I just have a casual interest in this, and I also wanted to try docker. I am prepared to believe long install instructions would work for me, but am happy to wait until you have a chance to update the docker package.

Thanks @nethsix

[nethsix]

I've updated the docker image. Updated the tools/docker/Dockerfile as well. Pull requested some updates to using Docker on the README.

I have tested the new instructions and new docker image, and it all works perfectly. Thank you for your help.
