Why SyntaxNet demo.sh is not finding correct imports?

Question

I went through https://github.com/tensorflow/models/tree/master/syntaxnet and did everything it says.

I ran this to test:

bazel test --linkopt=-headerpad_max_install_names \
    syntaxnet/... util/utf8/...

I could only make 6 test pass and 6 fails.

But when I run the demo, I am getting error.

User:syntaxnet hk$ echo "Parsey McParseface is my favorite parser" | syntaxnet/demo.sh

ImportError:     from tensorflow.python import pywrap_tensorflow
cannot import name pywrap_tensorflow
ImportError: cannot import name pywrap_tensorflow

what's going on? Is the demo.sh looking for those python imports in different place than where it is placed?

Try building and testing SyntaxNet once again using the bazel command. I encountered a quite similar error to this where bazel cannot find the python dir on my machine. After several tries of locating the python dir, bazel finished building and testing SyntaxNet with 1 fail test (a localhost error according to bazel), demo.sh works fine.

I tried building and testing Syntaxnet once again and good thing that this time it passed the 12 tests.

Executed 1 out of 12 tests: 12 tests pass.

And there's this additional reminder from bazel that might help:

There were tests whose specified size is too big. Use the --test_verbose_timeout_warnings command line option to see which ones these are.

Hope this helps.

Solved. I was missing some of the steps in bazel installation, in particular, 'Getting bash completion'. I thought that was only for jdk7.
