Drake: Building Drake in a Docker Container "typo"

[Islam0mar]

at http://drake.mit.edu/docker.html
cd /drake
$ bazel run //drake/examples/contact_model:bowling_ball
$ bazel run //drake/examples/kuka_iiwa_arm:kuka_simulation
$ bazel run //drake/examples/kuka_iiwa_arm

Should be $ bazel run //examples/...

Also in drake/setup/docker/Dockerfile.ubuntu16.04.***
line 8: bazel build //examples/acrobot:acrobot_run_passive
should be bazel build //examples/acrobot:run_passive

BTW: Why python in drake visualizer import pydrake while in normal console gives "ImportError: No module named pydrake"?

Thanks.

Assigning to @EricCousineau-TRI as related to #7654.

Thanks for letting us know! I've just submitted #8501 to fix this.

BTW: Why python in drake visualizer import pydrake while in normal console gives "ImportError: No module named pydrake"?

This is because the Bazel version of drake-visualizer does not include pydrake, as it greatly increases the build time.

Can I ask what your use case for pydrake inside of drake-visualizer is? Is it something you could use a packaged binary of Drake for?

If not, we could provide a drake_visualizer flavor which also includes pydrake.

I get this repeated error while testing:
error: cpp_template_test.py uses drake_py_unittest but is marked executable in the filesystem; fix this via chmod a-x cpp_template_test.py

I meant that in drake-visualizer' python console when I run pydrake, it gives no error, but in normal bash python it gives "ImportError: No module named pydrake".
Do I have to first open drake-visualizer then run my code? I want a newbie example for using inside docker without network and use MIT 6.832 examples.

Not sure why you're getting those errors, as cpp_template_test.py is not marked executable in Git (at least in the version that I have cloned).
Would you be able to make a StackOverflow post about the cpp_template_test.py issue, use the drake tag, and post what platform you're generating your Docker image from?
(Seems like the file's executable bit is getting set via something like Cygwin in Windows, copied to the Docker image, and then failing the drake_py_unittest.)

For using pydrake from Python in a normal Bash session, you need to ensure that your PYTHONPATH is set correctly:
